I set up 8 Hosts and self-hosted-engine running HA on 3 of them from
gluster replica 3 Volume. HA is working, I can set one host of the 3
configured for hosted-engine to maintenance and engine migrates to other
host. I did the hosted-engine --deploy with type gluster and my gluster
hosted storage is accessed as glusterfs.mydomain.de:/engine

I set up another gluster volume (distributed replicated 4x2=8) as Data
storage for my virtual machines which is accessible as
glusterfs.mydomain.de:/gv0.  ISO and Export Volume are defined from NFS

When I set up a VM on the gluster storage I expected it to run with
native gluster support. However if I dumpxml the libvirt machine
definition I've something like that in it's config:


    <disk type='file' device='disk' snapshot='no'>
      <driver name='qemu' type='raw' cache='none' error_policy='stop'
      <target dev='vda' bus='virtio'/>
      <boot order='1'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06'

I expected to have something like this:
<disk type='network' device='disk'>
    <driver name='qemu' type='raw' cache='none' error_policy='stop'
          <source protocol='gluster'
          <host name='glusterfs.mydomain.de'/>

All hosts have vdsm-gluster gluster installed:
[root at microcloud21 libvirt]# yum list installed | grep vdsm-*
vdsm.noarch                           4.17.28-0.el7.centos       @ovirt-3.6
vdsm-cli.noarch                       4.17.28-0.el7.centos       @ovirt-3.6

vdsm-infra.noarch                     4.17.28-0.el7.centos       @ovirt-3.6
vdsm-jsonrpc.noarch                   4.17.28-0.el7.centos       @ovirt-3.6
vdsm-python.noarch                    4.17.28-0.el7.centos       @ovirt-3.6
vdsm-xmlrpc.noarch                    4.17.28-0.el7.centos       @ovirt-3.6
vdsm-yajsonrpc.noarch                 4.17.28-0.el7.centos       @ovirt-3.6

How do I get my most wanted feature native gluster support running ?
