Hi there,
Let's assume a libvirt event occurred on a VM, i.e an event like pause VM or reboot VM or any other libvirt event. Can the VM determine that such event was originated by libvirt? ---or in a more general term by the hypervisor? If yes, how can this be done in theory?
Thanks in advance,

How are you thinking that a VM would be paused/rebooted via something other then the hypervisor?

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
