Installation, Upgrade, and Migration Issues
-
If you update your vCenter to 8.0 Update 1, but ESXi hosts remain on an earlier version, vSphere Virtual Volumes datastores on such hosts might become inaccessible
Self-signed VASA provider certificates are no longer supported in vSphere 8.0 and the configuration option
Config.HostAgent.ssl.keyStore.allowSelfSignedis set tofalseby default. If you update a vCenter instance to 8.0 Update 1 that introduces vSphere APIs for Storage Awareness (VASA) version 5.0, and ESXi hosts remain on an earlier vSphere and VASA version, hosts that use self-signed certificates might not be able to access vSphere Virtual Volumes datastores or cannot refresh the CA certificate.Workaround: Update hosts to ESXi 8.0 Update 1. If you do not update to ESXi 8.0 Update 1, see VMware knowledge base article 91387.
-
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:
-
Enable the option
media-auto-detectin 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. -
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_coredriver, such asdevice_rss,drssandrss, 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,drssandrssparameters as follows:-
device_rss: Use theDRSSparameter. -
drss: Use theDRSSparameter. -
rss: Use theRSSparameter.
-
-
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.getcommand from theapplianceshshell. If you use VAMI, refresh your browser.
Miscellaneous Issues
-
RDMA over Converged Ethernet (RoCE) traffic might fail in Enhanced Networking Stack (ENS) and VLAN environment, and a Broadcom RDMA network interface controller (RNIC)
The VMware solution for high bandwidth, ENS, does not support MAC VLAN filters. However, a RDMA application that runs on a Broadcom RNIC in an ENS + VLAN environment, requires a MAC VLAN filter. As a result, you might see some RoCE traffic disconnected. The issue is likely to occur in a NVMe over RDMA + ENS + VLAN environment, or in an ENS+VLAN+RDMA app environment, when an ESXi host reboots or an uplink goes up and down.
Workaround: None
-
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.
-
You cannot mount an IPv6-based NFS 3 datastore with VMkernel port binding by using ESXCLI commands
When you try to mount an NFS 3 datastore with an IPv6 server address and VMkernel port binding by using an ESXCLI command, the task fails with an error such as:
[:~] esxcli storage nfs add -I fc00:xxx:xxx:xx::xxx:vmk1 -s share1 -v volume1Validation of vmknic failed Instance(defaultTcpipStack, xxx:xxx:xx::xxx:vmk1) Input(): Not found:The issue is specific for NFS 3 datastores with an IPv6 server address and VMkernel port binding.
Workaround: Use the vSphere Client as an alternative to mount IPv6-based NFSv3 datastores with VMkernel port binding.
-
Reset or restore of the ESXi system configuration in a vSphere system with DPUs might cause invalid state of the DPUs
If you reset or restore the ESXi system configuration in a vSphere system with DPUs, for example, by selecting Reset System Configuration in the direct console, the operation might cause invalid state of the DPUs. In the DCUI, you might see errors such as
Failed to reset system configuration. Note that this operation cannot be performed when a managed DPU is present. A backend call to the-fforce reboot option is not supported for ESXi installations with a DPU. Although ESXi 8.0 supports the-fforce reboot option, if you usereboot -fon an ESXi configuration with a DPU, the forceful reboot might cause an invalid state.Workaround: Reset System Configuration in the direct console interface is temporarily disabled. Avoid resetting the ESXi system configuration in a vSphere system with DPUs.
-
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
vSwitchBMCwith uplinkvusb0gets 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/BMCNetworkEnableto prevent the creation of a virtual switchvSwitchBMCand associated portgroups on the next reboot of host.See this script as an example:
~# esxcfg-advcfg -s 0 /Net/BMCNetworkEnableThe value of BMCNetworkEnable is 0 and the service is disabled.
~# rebootOn 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.
-
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 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
-
ESXi reboot takes long due to NFS server mount timeout
When you have multiple mounts on an NFS server that is not accessible, ESXi retries connection to each mount for 30 seconds, which might add up to minutes of ESXi reboot delay, depending on the number of mounts.
Workaround: ESXi Update 8.0 Update 1 adds a configurable option to override the default mount timeout:
esxcfg-advcfg -s <timeout val> /NFS/MountTimeout. For example, if you want to reconfigure mount timeout to 10 seconds, you can run the following command:- esxcfg-advcfg -s 10 /NFS/MountTimeout. Use the commandesxcfg-advcfg -g /NFS/MountTimeoutto verify the current configured mount timeout. -
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
ntg3driver 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 onntg3drivers of versions earlier than 4.1.3 or thetg3driver. 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 antg3driver of version 4.1.7 or later, or disable EEE on physical switch ports.Workaround: Upgrade the
ntg3driver to version 4.1.8 and set the new module parameternoPhyStateSetto1. ThenoPhyStateSetparameter defaults to0and 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.logfile you see logs such asFailed 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
icendriver 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:
-
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.
-
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 failedin 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/coredirectory. The vpxa logs contain the lineToo many open files.Workaround: None. The vpxa service automatically restarts and corrects the issue.

If you use custom update repository with untrusted certificates, vCenter Server upgrade or update by using vCenter Lifecycle Manager workflows to vSphere 8.0 might fail
If you use a custom update repository with self-signed certificates that the VMware Certificate Authority (VMCA) does not trust, vCenter Lifecycle Manager fails to download files from such a repository. As a result, vCenter Server upgrade or update operations by using vCenter Lifecycle Manager workflows fail with the error
Failed to load the repository manifest data for the configured upgrade.Workaround: Use CLI, the GUI installer, or the Virtual Appliance Management Interface (VAMI) to perform the upgrade. For more information, see VMware knowledge base article 89493.
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.
vSphere Lifecycle Manager Issues
-
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 isTransition to OK.Workaround: Verify the descriptions for severity event states by using the ESXCLI command
esxcli hardware ipmi sdr listand Lenovo XCC.
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.
