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,
Regards,
Taimur

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
