Node shutdown takes 10Minutes because of stalled VM (timeout set to 80s)

[bfwdd]

To ensure a proper shutdown of the proxmox/ceph cluster in case of power
failure I experimented with setting a Timeout for quitting VMs.

I've used 80s, but if the VM hangs, it will be killed after 10minutes instead of 80s.
Where do this timeout of 10Minutes come from?

Any help appreciated!
With regards
Konrad

Thanks for your response,
Yes, agent was missing in VM, but activated in options.
If I disable agent in options, the VM properly shutdown, so I guess it uses ACPI-power signal ONLY with disabled agent.
Didn't know that.

For the record: KVM processes became unresponsive, had to be killed with -9
