Thanks,
I guess my query was clear. However, I'll make it clearer.
I know that the such events are caused by the hypervisor. Either directly
or using tools such as Libvirt. The question is: can such events be
detectable from the VM level? In another word, can the VM tell if it was
being paused/rebooted/migrated/etc?

Best regards,
Taimur
