Files left over after removing KVM guest

red888 asked:

Looking at this post I ran the following commands to remove a VM:

sudo rm /var/lib/libvirt/images/centos01.qcow2
sudo virsh undefine centos01 --managed-save --snapshots-metadata

But it looks like I still have some files pertaining to this image present:

find /var -name centos*
/var/log/libvirt/qemu/centos01.log
/var/lib/libvirt/qemu/centos01.monitor

Should I just delete these files? Will I run into a problem if I create a new VM with the same name?

Also, what is a .monitor file? I haven’t been able to find much info about what they do.

My answer:


These files are safe to delete as long as the corresponding VM is not running.

The log files are never deleted automatically when you undefine a VM; you can rotate or delete them yourself.

And the monitor is a socket by which you can connect to the VM’s internal qemu monitor. Not somehting you need if the VM no longer exists, and you don’t normally use it anyway.
