Proxmox VE already supports setting up a watchdog for virtual machines
emulated by QEMU, it's just not exposed on the web UI as it's a bit of
a niche feature. But you can use the API or CLI to configure one just
fine, for example:

Default model triggering a reset if watchdog isn't updated anymore:

qm set 1010 --watchdog action=reset

A different model doing a power off if guest OS doesn't update the
watchdog anymore:

qm set 1010 --watchdog model=ib700,action=poweroff
