snapshot with memory works as it should

@AlexanderKgr you can revert a disk to a disk snapshot and a vm to a vm snapshot. It seems you are trying to revert a vm to a disk snapshot. Is that correct?
Also you are describing in both examples restoring a powered off vm to a disk snapshot .
Am I misunderstanding your scenarios?
AlexanderKgr commentedon Dec 2, 2022
Let me clear this.
1st scenario tried to restore a disk snapshot while the instance is off (from cloudstack and from xen orchestra)
Received the error that hypervisor doesn't support guest os - while the instance was working normaly if booted.
It was for a colleague that he wanted to revert his instance to a previous state.
So tried the 2nd scenario.
Shuted down the instance only from console and tried to restored it from xen orchestra, where there wasn't any snapshot.
Tried from cloudstack to restore and i had the error that i couldn't restore disk in a running instance which is normal.
Tried scenarios with disk and memory and everything is working.
Summing up "disk" snapshots with xcp-ng does not work!
Please try it.

@AlexanderKgr
guest os mappings for 'Ubuntu 20.04 LTS" are missing for xenserver and vmware.
please update the template guest os type to "Ubuntu 18.04 LTS" and retry.
We will create a fix

the os mappings were added in #4672, but it was broken by #5911
fix: #7095

I experienced this with ACS 4.18.1 and XCP-ng as a hypervisor.
The message is IMHO wrong, the VM with Debian 12 worked fine before.
Could you reopen the issue? Or shall I create a new one?
