I manage an Ubuntu 14.04 LTS server running several guest VMs through KVM/qemu, and I'm asked to log boot, reboot and shutdown times of guests.
Is there a way to catch this kind of events for example in /var/log/syslog
?

I found that such events are already logged for each VM in a file named in a way similar to
vmname.log
, located in/var/log/libvirt/qemu/
.So one can get boot and shutdown times using a command like this:
Still can't find a way to get reboot time without looking at guest log files.
