Public bug reported:

Nova (Icehouse) appears to be enumerating all available libvirt volumes
(at least those in the "default" storage pool) during the "Auditing
locally available compute resources" process. If these images are not
readable by Nova it results in the following error:

2014-11-12 12:02:26.013 3009 ERROR nova.openstack.common.periodic_task [-] Error during ComputeManager.update_available_resource: Unexpected error while running command.
Command: env LC_ALL=C LANG=C qemu-img info /var/lib/libvirt/images/windows-1.qcow2
Exit code: 1
Stdout: u''
Stderr: u"qemu-img: Could not open '/var/lib/libvirt/images/windows-1.qcow2': Permission denied\n"

It's not clear to me why Nova is even attempting to run qemu-img on
these files.  They aren't exposed to or usable by Nova in any useful
fashion.   The filesystem where these images are stored is not utilized
by nova for storage.  They seem completely unrelated to anything Nova
cares about.

These errors prevent Nova from starting up correctly.
