[virt-tools-list] Questions about cdrom installation in virt-manager

[Cole Robinson]

When I tried it, I just entered the path like: /path/to/media.iso

If virt-manager doesn't find it in /var/lib/libvirt/images, it could be that
either the default pool needs to be refreshed, or if you are running as
non-root then maybe the app is getting confused because it can't manually
access /var/lib/libvirt/images. --debug info might have more hints. Remember
like I said below this will only work with virt-manager if you run as root
