Set chattr +C /var/lib/libvirt/images during libvirt installation
Last modified: 2016-06-09 10:04:03 EDT
Description of problem:
This is more of a suggestion. During the installation of libvirt the /var/lib/libvirt/images directory is created as a default place for virtual machines images. In case of installing on a system with COW filesystem such as btrfs or zfs one should disable copy-on-write on directories that will contain the images to avoid low IO performance.
This could be achieved by executing
chattr +C /var/lib/libvirt/images/
