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?

If one doubt validity of the host power management related to the guest,
there is always availability of the guest power management, in addition
to the 'virsh' power management, right.
Therefore,
man 1 virsh

basically, yes.  It's not (much) different than hibernate on laptops.

Actually the interesting question is what happens when they wake up? IOW
Does the suspended guest kernel know that it was suspended and for example
update its notion of the current time?

Just like any other process -- they will be suspended too.
