this is exactly what the HA stack provides

do you have two or three nodes ? reliable HA requires three nodes.

out of the box PVE4 and PVE5 works with a software defined watchdog
which will self fence the node if cluster communication is lost
see
https://pve.proxmox.com/pve-docs/chapter-ha-manager.html#ha_manager_fencing
for the fine docs

if the VM/CT is defined as a HA resource, it will be automically
restarted on another node when fencing takes place
