I was running a backup (snapshot).
I chose to stop the backup because I wanted to exclude a disk.
After stopping it, the guest wasn't running anymore:

i have a similar problem with recent proxmox

when i use "stop" in the backup task, then i get

INFO: issuing guest-agent 'fs-freeze' command
INFO: issuing guest-agent 'fs-thaw' command
INFO: started backup task '2ba4acfa-1d0d-49ef-8a19-f77db420eff4'
INFO: resuming VM again
INFO: 0% (54.4 MiB of 260.0 GiB) in 3s, read: 18.1 MiB/s, write: 17.8 MiB/s
INFO: 1% (2.6 GiB of 260.0 GiB) in 3m 13s, read: 13.8 MiB/s, write: 13.8 MiB/s
ERROR: interrupted by signal
INFO: aborting backup job

after that, in the task view i see "Error: unexpected status"

after that, i can still ping the affected VM, but i cannot login anymore. i get to an ssh loginprompt, but after login it times out, i guess I/O inside the vm is frozen

the guest is locked and i can get no console.

after "qm unlock" this is no better, i need to stop/reboot the VM
