<div>>><br><br></div></div><div>I failed to interpret 'mount point' here. If you are talking about 'gluster' volume server , the VM behaviour depends on the gluster configuration which indirectly depend on the quorum configuration and volume configuration. If there is an error from underlying storage ( here gluster volume) VM can pause , however latest versions of ovirt support auto resume.<br>

localhost as mount point if you are using compute & storage on the

<br></div><div>Please have a look at <a href="http://www.ovirt.org/Gluster_Storage_Domain_Reference" target="_blank">http://www.ovirt.org/Gluster_Storage_Domain_Reference</a> which talks about the recommended way of configuring it.<span><font color="#888888"><br>
