Check for additions and updates to these release notes.

What's New

The VMware Cloud Director 10.3.3 release provides bug fixes, API enhancements, and enhancements of the VMware Cloud Director appliance management user interface:

Backup and restore of VMware Cloud Director appliance certificates. VMware Cloud Director appliance management interface UI and API backup and restore now includes VMware Cloud Director certificates. See Backup and Restore of VMware Cloud Director Appliance in the VMware Cloud Director Installation, Configuration, and Upgrade Guide.
SSO login now requires user interaction before redirecting to the identity provider (IdP). When you navigate to an SSO enabled organization, you see a screen with the organization name and options to either log in with local credentials or to log in with SSO. Selecting the option to log in with SSO redirects you to the identity provider, similar to the behavior in earlier versions. With this feature, you can identify which organization you are signing in to before being redirected away from VMware Cloud Director.
New /admin/user/{id}/action/takeOwnership API to reassign the owner of media.
Improved support for routed vApp network configuration of the MoveVApp API.

This release resolves CVE-2022-22966. For information, see https://www.vmware.com/security/advisories.

If you migrate a VM, vApp, or independent disk to a vCenter Server instance that uses well-signed certificates, the migration fails

When trying to migrate a VM, vApp, or independent disk from one vCenter Server instance to another that uses well-signed certificates, the migration fails. The problem occurs when using the VMware Cloud Director UI and API requests like recompose, migrateVms, moveVApp, and so on.

Known Issues

New - VMware Cloud Director UI and tasks are slow to load and complete
The Artemis message bus communication is not working and when you trigger operations from the UI, they can take up to 5 minutes to complete or might time out. The performance issues can affect operations such as powering on VMs and vApps, provider VDC creation, vApp deployment, and so on.

The log files might contain an error message, such as:
- a) Connection failure to <VCD Cell IP Address> has been detected: AMQ229014: Did not receive data from <something> within the 60,000ms
- b) Connection failure to /<VCD Cell IP Address>:61616 has been detected: AMQ219014: Timed out after waiting 30,000 ms
- c) Bridge is stopping, will not retry
- d) Local Member is not set at on ClusterConnection ClusterConnectionImp
Workaround:

For a) and b):
1. Verify that the VMware Cloud Director cells have network connectivity and can communicate with each other.
2. Restart the VMware Cloud Director cell that contains the error message.
For c) and d), restart the VMware Cloud Director cell that contains the error message.
New - The VMware Cloud Director appliance database disk resize script might fail if the backing SCSI disk identifier changes

The database disk resize script runs successfully only if the backing database SCSI disk ID remains the same. If the ID changes for any reason, the script might appear to run successfully but fails. The /opt/vmware/var/log/vcd/db_diskresize.log shows that the script fails with a No such file or directory error.
Workaround:
1. Log in directly or by using an SSH client to the primary cell as root.
2. Run the lsblk --output NAME,FSTYPE,HCTL command.
3. In the output, find the disk containing the database_vg-vpostgres partition and make note of its ID. The ID is under the HCTL column and has the following sample format 2:0:3:0.
4. In the db_diskresize.sh script, modify the partition ID with the ID from Step 3. For example, if the ID is 2:0:3:0, in line
```
echo 1 > /sys/class/scsi_device/2\:0\:2\:0/device/rescan
```
  you must change the ID to 2:0:3:0.
```
echo 1 > /sys/class/scsi_device/2\:0\:3\:0/device/rescan
```
5. Аfter saving the changes, manually re-invoke the resize script or reboot the appliance.
New - Publishing a vRealize Orchestrator workflow to the VMware Cloud Director service library fails with an error message

When you attempt to publish a vRealize Orchestrator workflow, the operation fails with a 500 Server Error error message.

This happens because the API returns a large number of links for each individual tenant to which the workflow is published and causes an overflow in the HTTP headers.

Workaround: To publish the workflow, use CURL or POSTMAN to run an API request with increased HTTP header size limit.
New - When you use the VMware Cloud Director UI to create a new VM with a placement policy, all virtual machines that are part of the VM group defined in the used placement policy might disappear

When you use the VMware Cloud Director UI to create a new VM that uses a certain placement policy, all virtual machines listed in the VM group that's defined in the used placement policy might disappear from the VM group.

Workaround: When the VMs get deleted from the group, they become non-compliant with the placement policy that you used to create the new VM. To restore the VMs to the group, manually make each of them compliant with the used placement policy.
New - VMware Cloud Director operations, such as powering a VM on and off takes longer time to complete

VMware Cloud Director operations, such as powering a VM on or off takes longer time to complete. The task displays a Starting virtual machine status and nothing happens.

The jms-expired-messages.logs log file displays an error.

RELIABLE:LargeServerMessage & expiration=

Workaround: None.
New - NSX context profiles disappear after synchronization between VMware Cloud Director and NSX

If a large number of NSX context profiles are created for an edge gateway in VMware Cloud Director, sometimes the NSX context profiles don't sync correctly between VMware Cloud Director and NSX. As a result, some context profiles might get deleted. For information on NSX context profiles in VMware Cloud Director, see Create Custom Application Port Profiles.
New - Attempting to create a new application port profile fails with a duplicate error message

If two organization VDCs that are part of the same organization are backed by different NSX Manager instances, attempting to create an application port profile with the same name on both edge gateways might fail with the error message Application Port Profile already exists in Organization.
New - NSX context profiles disappear after synchronization between VMware Cloud Director and NSX

If a large number of NSX context profiles are created for an edge gateway in VMware Cloud Director, sometimes the NSX context profiles don't sync correctly between VMware Cloud Director and NSX. As a result, some context profiles might get deleted. For information on NSX context profiles in VMware Cloud Director, see Create Custom Application Port Profiles.
New - A VM with IP mode set to DHCP might not be able to connect to an external network

If a VM with IP mode set to DHCP is connected to a vApp network that uses port forwarding, the VM cannot connect to an external network. This happens because in NSX-backed organization VDCs, enabling IP masquerading for a vApp network does not create a corresponding SNAT rule on the vApp edge in NSX to allow outbound access for a VM without a static IP.

Workaround: Add to the vApp network a second vApp with a static IP and an explicit DNAT rule that allows access to the external network to the vApp network.
New - Migrating a VM that is connected to a vSphere-backed external network between resource pools fails

If a VM is connected to an external network which is backed by multiple vSphere networks, and you attempt to migrate the VM between resource pools, the operation fails if the source and destination resource pools are backed by different host clusters and if the destination resource pool does not have access to the external network to which the VM was originally connected.

Workaround: None.
Guest OS customizations like hostname and network do not work for the AlmaLinux OS

If you deploy an AlmaLinux template, VMware Cloud Director ignores the hostname and network configurations even when you force the guest customizations.

Workaround: Edit the /etc/redhat-release file to replace AlmaLinux with CentOS Linux.
New - Viewing the load balancer pools for an NSX edge gateway in the VMware Cloud Director UI might fail with a duplicate key error

Viewing the load balancer pools for an NSX edge gateways that uses NSX Advanced Load Balancing fails with Duplicate key error. This happens because of a failed automated creation of load balancing server pools with pool_backing_id set to null that are not used for any virtual services.

Workaround: Manually remove the server pools with pool_backing_id set to null from the VMware Cloud Director database.
New - Active Directory users cannot use the cell management tool on the VMware Cloud Director appliance
Active Directory users cannot run the cell management tool on the VMware Cloud Director appliance. The cell-management-tool.log file contains the following exception.
```
Unable to connect to the cell: Invalid credentials. Exiting. | java.lang.SecurityException: Invalid credentials at com.vmware.vcloud.common.jmx.VCloudJMXAuthenticator.authenticate
```
Workaround: None.
New - Running a custom workflow with external validation in vRO Workflow Execution UI plug-in fails with an Error performing external validation error message

When running a custom workflow with external validation through the vRO Workflow Execution UI plug-in, the process fails with an Error performing external validation error message. The issue occurs because vRealize Orchestrator does not perform validation on the inputs in the custom form in VMware Cloud Foundation.

Workaround: None.
New - The VMware Cloud Director dashboards for flex organization VDCs show incorrect CPU use

For flex organization VDCs, if the Make Allocation pool Org VDCs elastic option is activated, the flex organization VDC dashboard displays incorrect information about the vCPU use. For example, in a flex organization VDC with default vCPU speed of 1 GHz where the sizing policy defines the vCPU speed to 2GHz, if you create a VM, the dashboard incorrectly shows the vCPU use as 1 GHz. In the flex allocation model, the VM compute resource allocation depends on the VM sizing policies, and the real vCPU speed is 2GHz. When the Make Allocation pool Org VDCs elastic option is deactivated, the metrics appear correctly.

Workaround: None.
New - You cannot create VMware Cloud Director VDC templates in VMware Cloud Director service environments

VMware Cloud Director service does not support Virtual Data Center (VDC) templates. You can use VDC templates on environments with provider VDCs with an NSX network provider type or an NSX Data Center for vSphere provider type. You cannot use VDC templates on VMware Cloud Director service environments because the provider VDCs have the VMC network provider type.

Workaround: None.
New - VMs become non-compliant after converting a reservation pool VDC into a flex organization VDC

In an organization VDC with a reservation pool allocation model, if some of the VMs have nonzero reservation for CPU and Memory, non-unlimited configuration for CPU and Memory, or both, after converting into a flex organization VDC, these VMs become non-compliant. If you attempt to make the VMs compliant again, the system applies an incorrect policy for the reservation and limit and sets the CPU and Memory reservations to zero and the limits to Unlimited.
Workaround:
1. A system administrator must create a VM sizing policy with the correct configuration.
2. A system administrator must publish the new VM sizing policy to the converted flex organization VDC.
3. The tenants can use the VMware Cloud Director API or the VMware Cloud Director Tenant Portal to assign the VM sizing policy to the existing virtual machines in the flex organization VDC.
New - Migrating VMs between organization VDCs might fail with an insufficient resource error

If VMware Cloud Director is running with vCenter Server 7.0 Update 3h or earlier, when relocating a VM to a different organization VDC, the VM migration might fail with an insufficient resource error even if the resources are available in the target organization VDC.

Workaround: Upgrade vCenter Server to version 7.0 Update 3i or later.
New - Suspending a VM through the VMware Cloud Director UI results in a partially suspended state of the VM

In the VMware Cloud Director Tenant Portal, when you suspend a VM, VMware Cloud Director does not undeploy the VM, and the VM becomes Partially Suspended instead of Suspended.

Workaround: None.
New - Role name and description are localized in the VMware Cloud Director UI and can cause duplication of role names

The problem occurs because the UI translation does not affect the back end and API. You might create roles with the same names as the translated names which results in perceived duplicate roles in the UI and conflicts with the API usage of role names when creating service accounts.

Workaround: None.
New - The Customer Experience Improvement Program (CEIP) status is Enabled even after deactivating it during the installation of VMware Cloud Director

During the installation of VMware Cloud Director, if you deactivate the option to join the CEIP, after the installation completes, the CEIP status is active.

Workaround: Deactivate the CEIP by following the steps in the Join or Leave the VMware Customer Experience Improvement Program procedure.
New - When starting the VMware Cloud Director appliance, the message [FAILED] Failed to start Wait for Network to be Configured. See 'systemctl status systemd-networkd-wait-online.service' for details appears.

The message appears incorrectly and does not indicate an actual problem with the network. You can disregard the message and continue to use the VMware Cloud Director appliance as usual.

Workaround: None.

New - After VMware Cloud Director upgrade from version 10.2.2.x, adding a new node to the cluster fails with a file could not be found error

Upgrading VMware Cloud Director changes the location of the certificates.ks file which causes adding new nodes to fail with the following error.

Error: file could not be found: /opt/vmware/vcloud-director/user.http.pem
Error: invalid input: No valid HTTP SSL certificate provided

Workaround: Update the/opt/vmware/appliance/bin/setupvcd.sh script with the following commands.

#$VCLOUD_HOME/bin/configure --unattended-installation --primary-ip $ip --console-proxy-ip $ip --console-proxy-port-https 8443 -r $responsefile$VCLOUD_HOME/bin/configure --unattended-installation --primary-ip $ip --console-proxy-ip $ip --console-proxy-port-https 8443 --cert /opt/vmware/vcloud-director/etc/user.http.pem --key /opt/vmware/vcloud-director/etc/user.http.key --consoleproxy-cert /opt/vmware/vcloud-director/etc/user.consoleproxy.pem --consoleproxy-key /opt/vmware/vcloud-director/etc/user.consoleproxy.key -r $responsefile

New - VMware Cloud Director appliance upgrade fails with an invalid version error when FIPS mode is enabled

For VMware Cloud Director versions 10.3.x and later, when FIPS mode is enabled, VMware Cloud Director appliance upgrade fails with the following error.

Failure: Installation failed abnormally (program aborted), the current version may be invalid.
Workaround:
1. Before you upgrade the VMware Cloud Director appliance, deactivate FIPS Mode on the cells in the server group and the VMware Cloud Director appliance. See Activate or Deactivate FIPS Mode on the VMware Cloud Director Appliance.
2. Verify that the /etc/vmware/system_fips file does not exist on any appliance.
3. Upgrade the VMware Cloud Director appliance.
4. Enable FIPS mode again.
New - When performing a database upgrade for VMware Cloud Director, the upgrade fails with insert or update on table error

The issue occurs due to stale information in tables associated with a foreign key constraint. Missing data in one of the tables causes a conflict with the foreign key constraint.

See VMware knowledge base article 88010.
New - You cannot login to the VMware Cloud Director portals by using Single Sign On

When customizing the VMware Cloud Director portals, if you change the default configuration for the portalColor parameter, you cannot login to the portals by using Single Sign On. On the login page of the tenant portal, when you click on Sign In with Single Sign-On, the system redirects you back to the login page.

Workaround: Set the value for the portalColor parameter to null.
Refreshing the LDAP page in your browser does not take you back to the same page

In the Service Provider Admin Portal, refreshing the LDAP page in your browser takes you to the provider page instead of back to the LDAP page.

Workaround: None.
Mounting an NFS datastore from NetApp storage array fails with an error message during the initial VMware Cloud Director appliance configuration

During the initial VMware Cloud Director appliance configuration, if you configure an NFS datastore from NetApp storage array, the operation fails with an error message.

Backend validation of NFS failed with: is owned by an unknown user

Workaround: Configure the VMware Cloud Director appliance by using the VMware Cloud Director Appliance API.
The synchronization of a subscribed catalog times out while synchronizing large vApp templates

If an external catalog contains large vApp templates, synchronizing the subscribed catalog with the external catalog times out.This happens when the timeout setting is set to its default value of five minutes.

Workaround: Using the manage-config subcommand of the cell management tool, update the timeout configuration setting.

./cell-management-tool manage-config -n transfer.endpoint.socket.timeout -v [timeout-value]
After upgrade to VMware Cloud Director 10.3.2a, opening the list of external networks results in a warning message

When trying to open the list of external networks, the VMware Cloud Director UI displays a warning message.

One or more external networks or T0 Gateways have been disconnected from its IP address data.

This happens because the external network gets disconnected from the Classless Inter-Domain Routing (CIDR) configuration before the upgrade to VMware Cloud Director 10.3.2a.

Workaround: Contact VMware Global Support Services (GSS) for assistance with the workaround for this issue.
In an IP prefix list, configuring any as the Network value results in an error message

When creating an IP prefix list, if want to deny or accept any route and you configure the Network value as any, the dialog box displays an error message.

"any" is not a valid CIDR notation. A valid CIDR is a valid IP address followed by a slash and a number between 0 and 32 or 64, depending on the IP version.

Workaround: Leave the Network text box blank.
If you use vRealize Orchestrator 8.x, hidden input parameters in workflows are not populated automatically in the VMware Cloud Director UI

If you use vRealize Orchestrator 8.x, when you attempt to run a workflow through the VMware Cloud Director UI, hidden input parameters are not populated automatically in the VMware Cloud Director UI.
Workaround:To access the values of the workflow input parameters, you must create a vRealize Orchestrator action that has the same input parameter values as the workflow that you want to run.
1. Log in to the vRealize Orchestrator Client and navigate to Library>Workflows.
2. Select the Input Form tab and click Values on the right-hand side.
3. From the Value options drop-down menu, select External source,enter the Action inputs and click Save.
4. Run the workflow in the VMware Cloud Director UI.
The vpostgres process in a standby appliance fails to start

The vpostgres process in a standby appliance fails to start and the PostgreSQL log shows an error similar to the following. FATAL: hot standby is not possible because max_worker_processes = 8 is a lower setting than on the master server (its value was 16). This happens because PostgreSQL requires standby nodes to have the same max_worker_processes setting as the primary node. VMware Cloud Director automatically configures the max_worker_processes setting based on the number of vCPUs assigned to each appliance VM. If the standby appliance has fewer vCPUs than the primary appliance, this results in an error.

Workaround: Deploy the primary and standby appliances with the same number of vCPUs.
VMware Cloud Director API calls to retrieve vCenter Server information return a URL instead of a UUID

The issue occurs with vCenter Server instances that failed the initial registration with VMware Cloud Director version 10.2.1 and earlier. For those vCenter Server instances, when you make API calls to retrieve the vCenter Server information, the VMware Cloud Director API incorrectly returns a URL instead of the expected UUID.

Workaround: Reconnect to the vCenter Server instance to VMware Cloud Director.
Upgrading from VMware Cloud Director 10.2.x to VMware Cloud Director 10.3 results in an Connection to sfcbd lost error message

If you upgrade from VMware Cloud Director 10.2.x to VMware Cloud Director 10.3, the upgrade operation reports an error message.

Connection to sfcbd lost. Attempting to reconnect

Workaround: You can ignore the error message and continue with the upgrade.
When using FIPS mode, trying to upload OpenSSL-generated PKCS8 files fails with an error

OpenSSL cannot generate FIPS-complaint private keys. When VMware Cloud Director is in FIPS mode and you try to upload PKCS8 files generated using OpenSSL, the upload fails with a Bad request: org.bouncycastle.pkcs.PKCSException: unable to read encrypted data: ... not available: No such algorithm: ...error or salt must be at least 128 bits error.

Workaround: Deactivate the FIPS mode to upload the PKCS8 files.
Creation of Tanzu Kubernetes cluster by using the Kubernetes Container Clusters plug-in fails

When you create a Tanzu Kubernetes cluster by using the Kubernetes Container Clusters plug-in, you must select a Kubernetes version. Some of the versions in the drop-down menu are not compatible with the backing vSphere infrastructure. When you select an incompatible version, the cluster creation fails.

Workaround: Delete the failed cluster record and retry with a compatible Tanzu Kubernetes version. For information on the incompatibilities between Tanzu Kubernetes and vSphere, see Updating the vSphere with Tanzu Environment.
If you have any subscribed catalogs in your organization, when you upgrade VMware Cloud Director, the catalog synchronization fails

After upgrade, if you have subscribed catalogs in your organization, VMware Cloud Director does not trust the published endpoint certificates automatically. Without trusting the certificates, the content library fails to synchronize.

Workaround: Manually trust the certificates for each catalog subscription. When you edit the catalog subscription settings, a trust on first use (TOFU) dialog prompts you to trust the remote catalog certificate.

If you do not have the necessary rights to trust the certificate, contact your organization administrator.
After upgrading VMware Cloud Director and enabling the Tanzu Kubernetes cluster creation, no automatically generated policy is available and you cannot create or publish a policy

When you upgrade VMware Cloud Director to version 10.3.1 and vCenter Server to version 7.0.0d or later, and you create a provider VDC backed by a Supervisor Cluster, VMware Cloud Director displays a Kubernetes icon next to the VDC. However, there is no automatically generated Kubernetes policy in the new provider VDC. When you try to create or publish a Kubernetes policy to an organization VDC, no machine classes are available.

Workaround: Manually trust the corresponding Kubernetes endpoint certificates. See VMware knowledge base article 83583.
Entering a Kubernetes cluster name with non-Latin characters deactivates the Next button in the Create New Cluster wizard

The Kubernetes Container Clusters plug-in supports only Latin characters. If you enter non-Latin characters, the following error appears.

Name must start with a letter and only contain alphanumeric or hyphen (-) characters. (Max 128 characters).

Workaround: None.
NFS downtime can cause VMware Cloud Director appliance cluster functionalities to malfunction

If the NFS is unavailable due to the NFS share being full, becoming read only, and so on, can cause appliance cluster functionalities to malfunction. HTML5 UI is unresponsive while the NFS is down or cannot be reached. Other functionalities that might be affected are the fencing out of a failed primary cell, switchover, promoting a standby cell, and so on. For more information about setting up correctly the NFS shared storage, see Preparing the Transfer Server Storage for the VMware Cloud Director Appliance.
Workaround:
- Fix the NFS state so that it is not read-only.
- Clean up the NFS share if it is full.
Trying to encrypt named disks in vCenter Server version 6.5 or earlier fails with an error

For vCenter Server instances version 6.5 or earlier, if you try to associate new or existing named disks with an encryption enabled policy, the operation fails with a Named disk encryption is not supported in this version of vCenter Server. error.

Workaround: None.
A fast-provisioned virtual machine created on a VMware vSphere Storage APIs Array Integration (VAAI) enabled NFS array, or vSphere Virtual Volumes (VVols) cannot be consolidated

In-place consolidation of a fast provisioned virtual machine is not supported when a native snapshot is used. Native snapshots are always used by VAAI-enabled datastores, as well as by VVols. When a fast-provisioned virtual machine is deployed to one of these storage containers, that virtual machine cannot be consolidated .

Workaround: Do not enable fast provisioning for an organization VDC that uses VAAI-enabled NFS or VVols. To consolidate a virtual machine with a snapshot on a VAAI or a VVol datastore, relocate the virtual machine to a different storage container.
If you add an IPv6 NIC to a VM and then you add an IPv4 NIC to the same VM, the IPv4 north-south traffic breaks

Using the HTML5 UI, if you add an IPv6 NIC first or configure an IPv6 NIC as the primary NIC in a VM, and then you add an IPv4 NIC to the same VM, the IPv4 north-south communication breaks.

Workaround: First you must add the IPv4 NIC to the VM and then the IPv6 NIC.
