Suspend (not shutdown) VMs on TrueNAS Core host reboot

[AleksB]

Hi,

Is there a way to tell VMs to suspend to disk (not shutdown) when TrueNAS Core host is being rebooted? I've seen a topic, but it just shutsdown the VMs... Can't figure out how to suspend them instead.

I tried to use `virsh managedsave`, but it doesn't seem to work:

$ virsh managedsave 3_al2023 --running
error: Failed to save domain '3_al2023' state
error: this function is not supported by the connection driver: virDomainManagedSave
