Thanks Michal.
Yes I do not have a screen, the host and the guests are running on an embedded device.
The real requirement is:
Is there a way that I can register with libvirt for the state change notifications in the guest OS?
Is it possible?
I need to take some actions in the host based on the guest OS state change.

Thx

Well, I don't quite understand how would you do this on real host other
than looking at its screen.
Anyway, libvirt allows mgmt applications to peek into guest memory and
dump it. This is how virt-dmesg works [1]. So maybe it would be handful
example for you.
