[virt-tools-list] [patch] fix source name attribute for gluster volumes

[Anatoly.Belikov.wormblood at gmail.com]

Hello!!
I found that virt-install truncates disk path for gluster volumes. Xml always looks like this:
<disk type='network' device='disk'>
<source protocol='gluster' name='gluster_volname/disk_filename'>
</disk>

Instead of disk filename should be path relative to gluster volume root.
