[Bugs] [Bug 1058300] VMs do not resume after paused state and storage connection to a gluster domain (they will also fail to be manually resumed)

--- Comment #41 from Christopher <kripper at gmail.com> ---
Ok. One VM is unable to resume.
The reason in my case seems to be "Transport endpoint is not connected"
(http://www.gluster.org/community/documentation/index.php/Transport_endpoint_is_not_connected)

To reproduce, I'm just stopping and restarting a gluster volume (with no
replica).

This are the libvirtd logs:
