Many Avaya products that are certified to deploy on Avaya Solutions Platform (for example, Avaya Aura® documentation) refer to snapshots at the application level for various procedures. Snapshots apply to a VMware environment.
With the introduction of the alternative hypervisor in Avaya Solutions Platform R6.0.x (KVM on RHEL 8.10), Red Hat does not support VM snapshots on RHEL 8.10. While the command may be present in the OS, use of the command is not allowed as the resulting snapshot will be corrupt.
Virtual Machine Backup (clone) is a feature similar to snapshots. Virtual Machine Backup uses the cloning feature. Use virtual machine backups in place of snapshots for KVM on RHEL 8.10.
Reference application specific documentation for detailed instructions on how to utilize the Virtual Machine Backup (clone).
Note:
Use of the Virtual Machine Backup (clone) requires that the virtual machine be powered off. The space needed for a Virtual Machine Backup is equivalent to the size of the Virtual Machine that is being backed up. It is critical to remove Virtual Machine Backups as soon as possible, no later than 48 hours after they are created, and to always assess available disk space prior to performing a Virtual Machine Backup.
