- What problems can I expect to have with VMs added/modified since the last backup?
Modified VMs will be reverted to the previous configuration; additional VMs should be seen as external VMs, then you could import.Given VDSM kept the VMs up whilst the HE's been down, how will the running VMs that were present before & after the backup be affected?
Many of the VMs that were present during the last backup are now on different hosts, including the HE VM. Will that cause any issues?For normal VMs I don't expect any issue: the engine will simply update the correspondent record once it will find them on the managed hosts.A serious issue could instead happen with HA VMs:if the engine finds earlier an HA VM as running on a different host it will simply update its record, the issue is if it finds earlier the VM a not on the original host since it will try to restart it causing a split brain and probably a VM corruption.I opened a bug to track it:
