permissions are still unchanged?
From:
https://pve.proxmox.com/pve-docs/api-viewer/index.html#/nodes/{node}/qemu/{vmid}/status/suspend
"You need 'VM.PowerMgmt' on /vms/{vmid}, and if you have set 'todisk', you need
also
'VM.Config.Disk' on /vms/{vmid} and 'Datastore.AllocateSpace' on the storage
for the
vmstate."
But you call PVE::API2::Qemu->vm_suspend directly, so all schema based checks,
i.e., those not
done there in code directly, get circumvented.
Did you checked that this is OK??

I'd even enable this by defaults, prime use case.
Could be defaulted to true via gui to, as alternative.

a state storage maybe also useful, some may even want a mapping per VM? could
be overkill
though as people can already configure state storage in the VM options.
