Proxmox 8.1.3 (proxmox 8.0.x is working properly in this case)
ZFS 2.2.x
Snapshot VM with enabled qemu-gest -> frozen drive(s) inside VM (both win and lin)
Workarounds:
1. Disable iothread option on the SCSI drives (worse performance)
OR
2. "Pause" the VM for the snapshot moment (this will make the qemu agent unavailable and will omit fsfreeze) - WARNING this method may snapshot volumes in an inconsistent state!
OR
3. Don't use snapshots
[edit]
4. Pause and Resume VM AFTER the snapshot, taken from here:
doesn't actually work, it seems to work but not fully? Needs testing?
