Resolved Issues

Security Issues

  • After upgrade to vCenter Server 8.0, synchronization of password-protected subscribed content libraries might fail

    After upgrade to vCenter Server 8.0, synchronization of password-protected subscribed content libraries might fail due to missing security key details. In the logs, you see an error such as: javax.crypto.BadPaddingException: Error finalising cipher data: pad block corrupted.

    This issue is resolved in this release.

Networking Issues

  • LoadBalancers and Guest Clusters are not created when two SE Groups exist on NSX-ALB

    If a second SE Group is added to NSX-ALB with or without SEs or virtual services assigned to it, the creation of new supervisor or guest clusters fails, and existing supervisor clusters cannot be upgraded. The virtual service creation on NSX-ALB controller fails with the following error:

    get() returned more than one ServiceEngineGroup – it returned 2

    As a result, new load balancers are unusable and you cannot create new workload clusters successfully.

    For more information, see the VMware Knowledge Base article 90386.

    This issue is resolved in this release.

Known Issues

Installation and Upgrade Issues

  • vCenter Server update fails with error for failed load of repository manifest data

    If you set up a custom repository that has authentication and self-signed certificates that vCenter Server does not trust, updates and upgrades to vCenter Server 8.0 and later might fail. In the vSphere Client, you see an error such as Failed to load the repository manifest data for the configured upgrade after the upgrade precheck completes.

    Workaround: See VMware knowledge base article 90259.

Miscellaneous Issues

  • You cannot revert configuration changes for the vmware-rbd-watchdog service

    When you use the TLS Configuration utility to revert configuration changes, the vmware-rbd-watchdog service does not restore back to the expected TLS protocols.

    Workaround: Use the argument -s <service-name> to individually call the rbd service, for example: root@sc1-10-168-175-98 [ /usr/lib/vmware-TlsReconfigurator/VcTlsReconfigurator ]# ./reconfigureVc restore -d /tmp/20221124T100959 -s vmware-rbd-watchdog

Known Issues from Previous Releases

Installation, Upgrade, and Migration Issues

  • If you apply a host profile using a software FCoE configuration to an ESXi 8.0 host, the operation fails with a validation error

    Starting from vSphere 7.0, software FCoE is deprecated, and in vSphere 8.0 software FCoE profiles are not supported. If you try to apply a host profile from an earlier version to an ESXi 8.0 host, for example to edit the host customization, the operation fails. In the vSphere Client, you see an error such as Host Customizations validation error.

    Workaround: Disable the Software FCoE Configuration subprofile in the host profile.

  • You cannot use ESXi hosts of version 8.0 as a reference host for existing host profiles of earlier ESXi versions

    Validation of existing host profiles for ESXi versions 7.x, 6.7.x and 6.5.x fails when only an 8.0 reference host is available in the inventory.

    Workaround: Make sure you have a reference host of the respective version in the inventory. For example, use an ESXi 7.0 Update 2 reference host to update or edit an ESXi 7.0 Update 2 host profile.

  • VMNICs might be down after an upgrade to ESXi 8.0

    If the peer physical switch of a VMNIC does not support Media Auto Detect, or Media Auto Detect is disabled, and the VMNIC link is set down and then up, the link remains down after upgrade to or installation of ESXi 8.0.

    Workaround: Use either of these 2 options:

    1. Enable the option media-auto-detect in the BIOS settings by navigating to System Setup Main Menu, usually by pressing F2 or opening a virtual console, and then Device Settings > <specific broadcom NIC> > Device Configuration Menu > Media Auto Detect. Reboot the host.

    2. Alternatively, use an ESXCLI command similar to: esxcli network nic set -S <your speed> -D full -n <your nic>. With this option, you also set a fixed speed to the link, and it does not require a reboot.

  • If a vCenter Server Security Token Service (STS) refresh happens during upgrade to ESXi 8.0, the upgrade might fail

    In vSphere 8.0, vCenter Single Sign-On automatically renews a VMCA-generated STS signing certificate. The auto-renewal occurs before the STS signing certificate expires and before triggering the 90-day expiration alarm. However, in long-running upgrade or remediation tasks by using a vSphere Lifecycle Manager image on multiple ESXi hosts in a cluster, vSphere Lifecycle Manager might create a cache of STS certificates internally. In very rare cases, if an STS certificates refresh task starts in parallel with the long-running upgrade or remediation task, the upgrade task might fail as the STS certificates in the internal cache might be different from the refreshed certificates. After the upgrade task fails, some ESXi hosts might remain in maintenance mode.

    Workaround: Manually exit any ESXi hosts in maintenance mode and retry the upgrade or remediation. Refreshing or importing and replacing the STS signing certificates happens automatically and does not require a vCenter Server restart, to avoid downtime.

  • After upgrade to ESXi 8.0, you might lose some nmlx5_core driver module settings due to obsolete parameters

    Some module parameters for the nmlx5_core driver, such as device_rss, drss and rss, are deprecated in ESXi 8.0 and any custom values, different from the default values, are not kept after an upgrade to ESXi 8.0.

    Workaround: Replace the values of the device_rss, drss and rss parameters as follows:

    • device_rss: Use the DRSS parameter.

    • drss: Use the DRSS parameter.

    • rss: Use the RSS parameter.

  • Second stage of vCenter Server restore procedure freezes at 90%

    When you use the vCenter Server GUI installer or the vCenter Server Appliance Management Interface (VAMI) to restore a vCenter from a file-based backup, the restore workflow might freeze at 90% with an error 401 Unable to authenticate user, even though the task completes successfully in the backend. The issue occurs if the deployed machine has a different time than the NTP server, which requires a time sync. As a result of the time sync, clock skew might fail the running session of the GUI or VAMI.

    Workaround: If you use the GUI installer, you can get the restore status by using the restore.job.get command from the appliancesh shell. If you use VAMI, refresh your browser.

Miscellaneous Issues

  • In the vSphere API Explorer, VMware Datacenter CLI (DCLI) and PowerCLI, you see an API option "contentinternal" that is not functional

    You see an API option contentinternal in the metadata of either the vSphere API Explorer, DCLI and PowerCLI. For example, when you open https://<your vCenter IP>/ui/app/devcenter/api-explorer, you see the option in the select API drop-down menu. This option is not functional.

    Workaround: Ignore the contentinternal API option and do not use it.

  • If a PCI passthrough is active on a DPU during the shutdown or restart of an ESXi host, the host fails with a purple diagnostic screen

    If an active virtual machine has a PCI passthrough to a DPU at the time of shutdown or reboot of an ESXi host, the host fails with a purple diagnostic screen. The issue is specific for systems with DPUs and only in case of VMs that use PCI passthrough to the DPU.

    Workaround: Before shutdown or reboot of an ESXi host, make sure the host is in maintenance mode, or that no VMs that use PCI passthrough to a DPU are running. If you use auto start options for a virtual machine, the Autostart manager stops such VMs before shutdown or reboot of a host.

  • In a vCenter Server system with DPUs, if IPv6 is disabled, you cannot manage DPUs

    Although the vSphere Client allows the operation, if you disable IPv6 on an ESXi host with DPUs, you cannot use the DPUs, because the internal communication between the host and the devices depends on IPv6. The issue affects only ESXi hosts with DPUs.

    Workaround: Make sure IPv6 is enabled on ESXi hosts with DPUs.

  • You might see 10 min delay in rebooting an ESXi host on HPE server with pre-installed Pensando DPU

    In rare cases, HPE servers with pre-installed Pensando DPU might take more than 10 minutes to reboot in case of a failure of the DPU. As a result, ESXi hosts might fail with a purple diagnostic screen and the default wait time is 10 minutes.

    Workaround: None.

  • If you have an USB interface enabled in a remote management application that you use to install ESXi 8.0, you see an additional standard switch vSwitchBMC with uplink vusb0

    Starting with vSphere 8.0, in both Integrated Dell Remote Access Controller (iDRAC) and HP Integrated Lights Out (ILO), when you have an USB interface enabled, vUSB or vNIC respectively, an additional standard switch vSwitchBMC with uplink vusb0 gets created on the ESXi host. This is expected, in view of the introduction of data processing units (DPUs) on some servers but might cause the VMware Cloud Foundation Bring-Up process to fail.

    Workaround: Before vSphere 8.0 installation, disable the USB interface in the remote management application that you use by following vendor documentation.

    After vSphere 8.0 installation, use the ESXCLI command esxcfg-advcfg -s 0 /Net/BMCNetworkEnable to prevent the creation of a virtual switch vSwitchBMC and associated portgroups on the next reboot of host.

    See this script as an example:

    ~# esxcfg-advcfg -s 0 /Net/BMCNetworkEnable

    The value of BMCNetworkEnable is 0 and the service is disabled.

    ~# reboot

    On host reboot, no virtual switch, PortGroup and VMKNIC are created in the host related to remote management application network.

  • If an NVIDIA BlueField DPU is in hardware offload mode disabled, virtual machines with configured SR-IOV virtual function cannot power on

    NVIDIA BlueField DPUs must be in hardware offload mode enabled to allow virtual machines with configured SR-IOV virtual function to power on and operate.

    Workaround: Always use the default hardware offload mode enabled for NVIDIA BlueField DPUs when you have VMs with configured SR-IOV virtual function connected to a virtual switch.

  • Some ionic_en driver uplinks might work with just a single receive queue and you see slower performance in native mode

    Pensando Distributed Services Platform (DSC) adapters have 2 high speed ethernet controllers (for example vmnic6 and vmnic7) and one management controller (for example vmnic8):

    :~] esxcfg-nics -l

    vmnic6 0000:39:00.0 ionic_en_unstable Up 25000Mbps Full 00:ae:cd:09:c9:48 1500 Pensando Systems DSC-25 10/25G 2-port 4G RAM 8G eMMC G1 Services Card, Ethernet Controller

    vmnic7 0000:3a:00.0 ionic_en_unstable Up 25000Mbps Full 00:ae:cd:09:c9:49 1500 Pensando Systems DSC-25 10/25G 2-port 4G RAM 8G eMMC G1 Services Card, Ethernet Controller

    :~] esxcfg-nics -lS

    vmnic8 0000:3b:00.0 ionic_en_unstable Up 1000Mbps Full 00:ae:cd:09:c9:4a 1500 Pensando Systems DSC-25 10/25G 2-port 4G RAM 8G eMMC G1 Services Card, Management Controller

    The high-speed ethernet controllers vmnic6 and vmnic7 register first and operate with RSS set to 16 receive queues.

    :~] localcli --plugin-dir /usr/lib/vmware/esxcli/int networkinternal nic privstats get -n vmnic6…Num of RSS-Q=16, ntxq_descs=2048, nrxq_descs=1024, log_level=3, vlan_tx_insert=1, vlan_rx_strip=1, geneve_offload=1 }

    However, in rare cases, if the management controller vmnic8 registers first with the vSphere Distributed Switch, the high-speed ethernet controllers vmnic6 or vmnic7 uplink might end up operating with RSS set to 1 receive queue.:~] localcli --plugin-dir /usr/lib/vmware/esxcli/int networkinternal nic privstats get -n vmnic6…Num of RSS-Q=1, ntxq_descs=2048, nrxq_descs=1024, log_level=3, vlan_tx_insert=1, vlan_rx_strip=1, geneve_offload=1 }

    As a result, you might see slower performance in native mode.

    Workaround: Reload the ionic_en driver on ESXi by using the following commands::~] esxcfg-module -u ionic_en:~] esxcfg-module ionic_en:~] localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal bind.

  • In the Virtual Appliance Management Interface (VAMI), you see a warning message during the pre-upgrade stage

    Moving vSphere plug-ins to a remote plug-in architecture, vSphere 8.0 deprecates support for local plug-ins. If your 8.0 vSphere environment has local plug-ins, some breaking changes for such plug-ins might cause the pre-upgrade check by using VAMI to fail.

    In the Pre-Update Check Results screen, you see an error such as:

    Warning message: The compatibility of plug-in package(s) %s with the new vCenter Server version cannot be validated. They may not function properly after vCenter Server upgrade.

    Resolution: Please contact the plug-in vendor and make sure the package is compatible with the new vCenter Server version.

    Workaround: Refer to the VMware Compatibility Guide and VMware Product Interoperability Matrix or contact the plug-in vendors for recommendations to make sure local plug-ins in your environment are compatible with vCenter Server 8.0 before you continue with the upgrade. For more information, see the blog Deprecating the Local Plugins :- The Next Step in vSphere Client Extensibility Evolution and VMware knowledge base article 87880.

  • You cannot remove a PCI passthrough device assigned to a virtual Non-Uniform Memory Access (NUMA) node from a virtual machine with CPU Hot Add enabled

    Although by default when you enable CPU Hot Add to allow the addition of vCPUs to a running virtual machine, virtual NUMA topology is deactivated, if you have a PCI passthrough device assigned to a NUMA node, attempts to remove the device end with an error. In the vSphere Client, you see messages such as Invalid virtual machine configuration. Virtual NUMA cannot be configured when CPU hotadd is enabled.

    Workaround: See VMware knowledge base article 89638.

  • If you deploy a virtual machine from an OVF file or from the Content Library, the number of cores per socket for the VM is set to 1

    If you deploy a virtual machine from an OVF file or from the Content Library, instead of ESXi automatically selecting the number of cores per socket, the number is pre-set to 1.

    Workaround: You can manually set the number of cores per socket by using the vSphere Client. For more information, see VMware knowledge base article 89639.

  • If you configure a VM at HW version earlier than 20 with a Vendor Device Group, such VMs might not work as expected

    Vendor Device Groups, which enable binding of high-speed networking devices and the GPU, are supported only on VMs with HW version 20 and later, but you are not prevented to configure a VM at HW version earlier than 20 with a Vendor Device Group. Such VMs might not work as expected: for example, fail to power-on.

    Workaround: Ensure that VM HW version is of version 20 before you configure a Vendor Device Group in that VM.

Networking Issues

  • You cannot set the Maximum Transmission Unit (MTU) on a VMware vSphere Distributed Switch to a value larger than 9174 on a Pensando DPU

    If you have the vSphere Distributed Services Engine feature with a Pensando DPU enabled on your ESXi 8.0 system, you cannot set the Maximum Transmission Unit (MTU) on a vSphere Distributed Switch to a value larger than 9174.

    Workaround: None.

  • You see link flapping on NICs that use the ntg3 driver of version 4.1.3 and later

    When two NICs that use the ntg3 driver of versions 4.1.3 and later are connected directly, not to a physical switch port, link flapping might occur. The issue does not occur on ntg3 drivers of versions earlier than 4.1.3 or the tg3 driver. This issue is not related to the occasional Energy Efficient Ethernet (EEE) link flapping on such NICs. The fix for the EEE issue is to use a ntg3 driver of version 4.1.7 or later, or disable EEE on physical switch ports.

    Workaround: Upgrade the ntg3 driver to version 4.1.8 and set the new module parameter noPhyStateSet to 1. The noPhyStateSet parameter defaults to 0 and is not required in most environments, except they face the issue.

  • VMware NSX installation or upgrade in a vSphere environment with DPUs might fail with a connectivity error

    An intermittent timing issue on the ESXi host side might cause NSX installation or upgrade in a vSphere environment with DPUs to fail. In the nsxapi.log file you see logs such as Failed to get SFHC response. MessageType MT_SOFTWARE_STATUS.

    Workaround: Wait for 10 min and retry the NSX install or upgrade.

  • If you do not reboot an ESXi host after you enable or disable SR-IOV with the icen driver, when you configure a transport node in ENS Interrupt mode on that host, some virtual machines might not get DHCP addresses

    If you enable or disable SR-IOV with the icen driver on an ESXi host and configure a transport node in ENS Interrupt mode, some Rx (receive) queues might not work if you do not reboot the host. As a result, some virtual machines might not get DHCP addresses.

    Workaround: Either add a transport node profile directly, without enabling SR-IOV, or reboot the ESXi host after you enable or disable SR-IOV.

  • You cannot use Mellanox ConnectX-5, ConnectX-6 cards Model 1 Level 2 and Model 2 for Enhanced Network Stack (ENS) mode in vSphere 8.0

    Due to hardware limitations, Model 1 Level 2, and Model 2 for Enhanced Network Stack (ENS) mode in vSphere 8.0 is not supported in ConnectX-5 and ConnectX-6 adapter cards.

    Workaround: Use Mellanox ConnectX-6 Lx and ConnectX-6 Dx or later cards that support ENS Model 1 Level 2, and Model 2A.

  • Pensando DPUs do not support Link Layer Discovery Protocol (LLDP) on physical switch ports of ESXi hosts

    When you enable LLDP on an ESXi host with a DPU, the host cannot receive LLDP packets.

    Workaround: None.

Storage Issues

  • VASA API version does not automatically refresh after upgrade to vCenter Server 8.0

    vCenter Server 8.0 supports VASA API version 4.0. However, after you upgrade your vCenter Server system to version 8.0, the VASA API version might not automatically change to 4.0. You see the issue in 2 cases:

    1. If a VASA provider that supports VASA API version 4.0 is registered with a previous version of VMware vCenter, the VASA API version remains unchanged after you upgrade to VMware vCenter 8.0. For example, if you upgrade a VMware vCenter system of version 7.x with a registered VASA provider that supports both VASA API versions 3.5 and 4.0, the VASA API version does not automatically change to 4.0, even though the VASA provider supports VASA API version 4.0. After the upgrade, when you navigate to vCenter Server > Configure > Storage Providers and expand the General tab of the registered VASA provider, you still see VASA API version 3.5.

    2. If you register a VASA provider that supports VASA API version 3.5 with a VMware vCenter 8.0 system and upgrade the VASA API version to 4.0, even after the upgrade, you still see VASA API version 3.5.

    Workaround: Unregister and re-register the VASA provider on the VMware vCenter 8.0 system.

  • vSphere Storage vMotion operations might fail in a vSAN environment due to an unauthenticated session of the Network File Copy (NFC) manager

    Migrations to a vSAN datastore by using vSphere Storage vMotion of virtual machines that have at least one snapshot and more than one virtual disk with different storage policy might fail. The issue occurs due to an unauthenticated session of the NFC manager because the Simple Object Access Protocol (SOAP) body exceeds the allowed size.

    Workaround: First migrate the VM home namespace and just one of the virtual disks. After the operation completes, perform a disk only migration of the remaining 2 disks.

  • You cannot create snapshots of virtual machines due to an error in the Content Based Read Cache (CBRC) that a digest operation has failed

    A rare race condition when assigning a content ID during the update of the CBRC digest file might cause a discrepancy between the content ID in the data disk and the digest disk. As a result, you cannot create virtual machine snapshots. You see an error such as An error occurred while saving the snapshot: A digest operation has failed in the backtrace. The snapshot creation task completes upon retry.

    Workaround: Retry the snapshot creation task.

vCenter Server and vSphere Client Issues

  • The Utilization view of resource pools and clusters might not automatically refresh when you change the object

    When you have already opened the Utilization view under the Monitor tab for a resource pool or a cluster and then you change the resource pool or cluster, the view might not automatically refresh. For example, when you open the Utilization view of one cluster and then select a different cluster, you might still see the statistics of the first cluster.

    Workaround: Click the refresh icon.

  • If you load the vSphere virtual infrastructure to more than 90%, ESXi hosts might intermittently disconnect from vCenter Server

    In rare occasions, if the vSphere virtual infrastructure is continuously using more than 90% of its hardware capacity, some ESXi hosts might intermittently disconnect from the vCenter Server. Connection typically restores within a few seconds.

    Workaround: If connection to vCenter Server accidentally does not restore in a few seconds, reconnect ESXi hosts manually by using vSphere Client.

  • In the vSphere Client, you do not see banner notifications for historical data imports

    Due to a backend issue, you do not see banner notifications for background migration of historical data in the vSphere Client.

    Workaround: Use the vCenter Server Management Interface as an alternative to the vSphere Client. For more information, see Monitor and Manage Historical Data Migration.

  • You see an error for Cloud Native Storage (CNS) block volumes created by using API in a mixed vCenter environment

    If your environment has vCenter Server systems of version 8.0 and 7.x, creating Cloud Native Storage (CNS) block volume by using API is successful, but you might see an error in the vSphere Client, when you navigate to see the CNS volume details. You see an error such as Failed to extract the requested data. Check vSphere Client logs for details. + TypeError: Cannot read properties of null (reading 'cluster'). The issue occurs only if you review volumes managed by the 7.x vCenter Server by using the vSphere Client of an 8.0 vCenter Server.

    Workaround: Log in to vSphere Client on a vCenter Server system of version 7.x to review the volume properties.

  • ESXi hosts might become unresponsive, and you see a vpxa dump file due to a rare condition of insufficient file descriptors for the request queue on vpxa

    In rare cases, when requests to the vpxa service take long, for example waiting for access to a slow datastore, the request queue on vpxa might exceed the limit of file descriptors. As a result, ESXi hosts might briefly become unresponsive, and you see a vpxa-zdump.00* file in the /var/core directory. The vpxa logs contain the line Too many open files.

    Workaround: None. The vpxa service automatically restarts and corrects the issue.

Virtual Machine Management Issues

  • When you add an existing virtual hard disk to a new virtual machine, you might see an error that the VM configuration is rejected

    When you add an existing virtual hard disk to a new virtual machine by using the VMware Host Client, the operation might fail with an error such as The VM configuration was rejected. Please see browser Console. The issue occurs because the VMware Host Client might fail to get some properties, such as the hard disk controller.

    Workaround: After you select a hard disk and go to the Ready to complete page, do not click Finish. Instead, return one step back, wait for the page to load, and then click Next > Finish.

Security Features Issues

  • If you use an RSA key size smaller than 2048 bits, RSA signature generation fails

    Starting from vSphere 8.0, ESXi uses the OpenSSL 3.0 FIPS provider. As part of the FIPS 186-4 requirement, the RSA key size must be at least 2048 bits for any signature generation, and signature generation with SHA1 is not supported.

    Workaround: Use RSA key size larger than 2048.

vSphere Lifecycle Manager Issues

  • If a parallel remediation task fails, you do not see the correct number of ESXi hosts that passed or skipped the operation

    With vSphere 8.0, you can enable vSphere Lifecycle Manager to remediate all hosts that are in maintenance mode in parallel instead of in sequence. However, if a parallel remediation task fails, in the vSphere Client you might not see the correct number of hosts that passed, failed, or skipped the operation, or even not see such counts at all. The issue does not affect the vSphere Lifecycle Manager functionality, but only the reporting in the vSphere Client.

    Workaround: None.

  • If you use an ESXi host deployed from a host profile with enabled stateful install as an image to deploy other ESXi hosts in a cluster, the operation fails

    If you extract an image of an ESXi host deployed from a host profile with enabled stateful install to deploy other ESXi hosts in a vSphere Lifecycle Manager cluster, the operation fails. In the vSphere Client, you see an error such as A general system error occurred: Failed to extract image from the host: no stored copy available for inactive VIB VMW_bootbank_xxx. Extraction of image from host xxx.eng.vmware.com failed.

    Workaround: Use a different host from the cluster to extract an image.

  • You see error messages when try to stage vSphere Lifecycle Manager Images on ESXi hosts of version earlier than 8.0

    ESXi 8.0 introduces the option to explicitly stage desired state images, which is the process of downloading depot components from the vSphere Lifecycle Manager depot to the ESXi hosts without applying the software and firmware updates immediately. However, staging of images is only supported on an ESXi 8.0 or later hosts. Attempting to stage a vSphere Lifecycle Manager image on ESXi hosts of version earlier than 8.0 results in messages that the staging of such hosts fails, and the hosts are skipped. This is expected behavior and does not indicate any failed functionality as all ESXi 8.0 or later hosts are staged with the specified desired image.

    Workaround: None. After you confirm that the affected ESXi hosts are of version earlier than 8.0, ignore the errors.

  • A remediation task by using vSphere Lifecycle Manager might intermittently fail on ESXi hosts with DPUs

    When you start a vSphere Lifecycle Manager remediation on an ESXi hosts with DPUs, the host upgrades and reboots as expected, but after the reboot, before completing the remediation task, you might see an error such as:

    A general system error occurred: After host … remediation completed, compliance check reported host as 'non-compliant'. The image on the host does not match the image set for the cluster. Retry the cluster remediation operation.

    This is a rare issue, caused by an intermittent timeout of the post-remediation scan on the DPU.

    Workaround: Reboot the ESXi host and re-run the vSphere Lifecycle Manager compliance check operation, which includes the post-remediation scan.

VMware Host Client Issues

  • VMware Host Client might display incorrect descriptions for severity event states

    When you look in the VMware Host Client to see the descriptions of the severity event states of an ESXi host, they might differ from the descriptions you see by using Intelligent Platform Management Interface (IPMI) or Lenovo XClarity Controller (XCC). For example, in the VMware Host Client, the description of the severity event state for the PSU Sensors might be Transition to Non-critical from OK, while in the XCC and IPMI, the description is Transition to OK.

    Workaround: Verify the descriptions for severity event states by using the ESXCLI command esxcli hardware ipmi sdr list and Lenovo XCC.

Guest OS Issues

  • The guest operating system of a VM might become unresponsive due to lost communication over the Virtual Machine Communication Interface (VMCI)

    In very specific circumstances, when a vSphere vMotion operation on a virtual machine runs in parallel with an operation that sends VMCI datagrams, services that use VMCI datagrams might see unexpected communication or loss of communication. Under the same conditions, the issue can also happen when restoring a memory snapshot, resuming a suspended VM or using CPU Hot Add. As a result, the guest operating system that depends on services communicating over VMCI might become unresponsive. The issue might also affect services that use vSockets over VMCI. This problem does not impact VMware Tools. The issue is specific for VMs on hardware version 20 with a Linux distribution that has specific patches introduced in Linux kernel 5.18 for a VMCI feature, including but not limited to up-to-date versions of RHEL 8.7, Ubuntu 22.04 and 22.10, and SLES15 SP3, and SP4.

    Workaround: Set the advanced option vmci.dmaDatagramSupport to FALSE. For more information, see VMware knowledge base article 89683.

  • Linux guest operating system cannot complete booting if Direct Memory Access (DMA) remapping is enabled

    If the advanced processor setting Enable IOMMU in this virtual machine is enabled on a virtual machine, and the guest operating system has enabled DMA remapping, the Linux guest operating system might fail to complete the booting process. This issue affects VMs with hardware version 20 and a Linux distribution that has specific patches introduced in Linux kernel 5.18 for a VMCI feature, including but not limited to up-to-date versions of RHEL 8.7, Ubuntu 22.04 and 22.10, and SLES15 SP3, and SP4.

    Workaround: Set the advanced option vmci.dmaDatagramSupport to FALSE or disable the Enable IOMMU in this virtual machine option. For more information, see VMware knowledge base article 89683.
