How to log kvm/qemu guest boot/reboot/shutdown time?
6,530
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:
$ sudo grep -e 'starting up' -e 'shutting down' /var/log/libvirt/qemu/vmname-log
Still can't find a way to get reboot time without looking at guest log files.

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

Admin over 7 years@AndrewDomaszek Thank for your comment, you put me on the right path: on my system
libvirtd.log
wasn't helpful, but files in/var/log/libvirt/qemu/
were. I added an answer to help others passing by.
