The following known issues exist in the current implementation:
-
For Huawei Cloud Stack 8.2.x, full VM restores may encounter failures in updating instance metadata, such as 'cascaded.instance_extrainfo' for instances created from volumes due to permission restrictions. To address this, you can skip specific metadata keys during the restore process by adding a configuration setting. This setting should include a comma- or space-separated list of the metadata keys you want to skip.
For example, to skip cascaded.instance_extrainfo, use the registry key sInstanceSkipMetadataKeys.
-
A backup can fail when the wrong GUID or UUID is returned during virtual machine discovery for the Linux proxy VM that is performing the backup. To resolve this issue, see article RHV0001.
-
For out-of-place restores, no network interface mapping is available. If the source instance was connected to an external network interface, the instance is restored without the external network interface. If the source instance was connected to a private network, the instance is restored with the private network interface.
-
Live browse and restore of files and folders is supported only from backups of disks using the QCOW2 file format.
-
For Windows instances created from an image, the base image files are not included in browse results and cannot be recovered using guest file and folder restores.
-
OpenStack entity names that include the backslash character ('\') are not supported. For example, a backup of an instance with a name such as vm_name\disk_name would result in indexing data with disk_name as a subfolder under vm_name.
-
If the user account that was specified for the OpenStack virtualization client does not have access to the key pair associated with the instance owner, the key pair cannot be restored with the instance. See VOPS0003: The key pair for a restored instance is empty if the user who performed the restore does not have access to the key pair for the original instance owner.
-
Commvault does not support backup and recovery for VMware hypervisors running on OpenStack.
-
For OpenStack, to filter the operating system disk, the CommServe computer’s locale environment must be set to US/English. This feature will not work if the locale environment is set to any other locale.
