stonith / fencing for guest VMs

Hi guys,

we are running few pacemaker cluster setups in our VMs (KVM), the problem is, sometimes resource migration doesn't work if a node is in undefined state, stonith (kill the VM) could resolve this problem, unfortunately I can't find any info if it possible with Proxmox. I know pacemaker's stonith works fine with libvirt, but Proxmox doesn't use it, so is there maybe another ways to achieve that?

Best,
Stan
