[UPS] preferred behavior in case of a power failure

I'm running several different OSes types on a single machine an like to suspend
them in case of a power failure. Since many of them can not be shutdown with
'qm shutdown <vmid>' or take to long to shutdown themselves I need to put
them on "hold". All VMs are using the local LVM storage.

Is it possible to suspend all VMs and save their state/memory to disk?

What is the preferred way to handle a power failure shutdown?

so far there is no such feature. preferred way is to have redundant power or VM/CTs which can do a clean shutdown if host goes down (e.g. because batteries are empty).
