A customer asked for a progress bar when suspending instances while shutting down the host.
Currently there is a progress shown for each instance. By calculating all instances together one could get a better overview of the remaining time.

FYI: Suspend is implemented in /usr/lib/libvirt/libvirt-guests.sh

There is no strong connection between "RAM size" and "suspend image size", so libvirtd can't know the size in advance, but only when the suspend started. As that is quiet IO have, suspending multiple VMs is serialized to not trash with storage system with multiple concurrent short writes.
As this was not asked for again and we have a progress bar per VM: WORKS-FOR-ME
