Failing to access something, when the something has permissions, usually
implies a problem with apparmor / SElinux.

If this is an Ubuntu platform, then use libvirt to start the VM (i.e. define
it using an XML file), and it should automatically create an apparmor policy
dynamically.  Otherwise, try turning off apparmor / SElinux temporarily to
see whether or that's the problem.  You could also try mounting your volume
directly onto /var/lib/libvirt/images.
