[pve-devel] vm stop tasks hanging

interesting: when I stop the process, I have this error:
command '/sbin/lvs --separator : --noheadings --units b --unbuffered --nosuffix --options vg_name,lv_name,lv_size,uuid,tags' failed: received interrupt
root at kvm6:~#
I'm using scsi lun directly without lvm, maybe this is the cause of the problem ?

What does an strace -f -p PID of the vm stop command say? It should do
or wait for something. Also does it only happen via Proxmox console or
does it also happen when starting then command via shell?
