Re: [libvirt-users] unable to edit existing snapshot

Greetings,
due to hardware failure I had to replace my workstation which has a

to a specific one.
I'll assume these are external snapshots? You might want to note how
exactly you created your snapshot (including the CLI).
While reverting to it, I get an error due to unsupported CPU
features.
Noting your exact error can be useful.
Therefore, I try to edit the snapshot XML through the command:
virsh snapshot-edit <domain_name> <snapshot_name>
When I save the changes I get the error message: error: intermal
error: unexpected domain snapshot <snapshot_name> already exists
Tried to look around for solution but didn't find any information
related to my problem.
Am I doing something wrong? It's quite critical for me to be able to
revert to that state of the machine. Is there any chance to do so via
libvirt?
Assuming you're referring to an external snapshot, maybe you can try the
manual operation of editing the domain's XML (not the snapshot's XML)
and point to the exact disk image that you want to revert to?
