What about KVM VMs when Suspending?

[Mihamina Rakotomandimby]

Hi all,

I read a bit about the difference between "Hibernate" and "Suspend".
I use my laptop as virtualization host too, and wonder what about the 
VMs when Suspending.

I works fairly well when no VM is launched.
What is suposed to happen if I have KVM VMs started?
