Investigate loop device problems.

Hey, our ovirt-node-iso job is regularly failing because of too many orphaned loop devices [0]. The loop devices seem to be orphaned partially by our but also by another job. I'd like to investigate this problem more and therefor request temporary access to fedora18-vm01. Greetings fabian [0] http://jenkins.ovirt.org/view/ovirt_node/job/ovirt-node-iso-devel/2410/co...
