Hello,

after upgradeing my whole cluster of 8 Hosts to ovirt 4.2.5 and setting compability of cluster and datacenter to 4.2 my existing virtual machines start using FUSE mounted disk-images on my gluster volumes.

One bad and slow thing I thought that I got rid of starting with 4.1.x finally !

Disk definition from virsh -r dumpxml VM of old running vm (not restarted yet !):
