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
