Hello,
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 Server.
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'>
I expected to have something like this:
<driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/>
<source file='/rhev/data-center/00000001-0001-0001-0001-0000000000b9/5d99af76-33b5-47d8-99da-1f32413c7bb0/images/011ab08e-71af-4d5b-a6a8-9b843a10329e/3f71d6c7-9b6d-4872-abc6-01a2b3329656'/>
<backingStore/>
<target dev='vda' bus='virtio'/>
<serial>011ab08e-71af-4d5b-a6a8-9b843a10329e</serial>
<boot order='1'/>
<alias name='virtio-disk0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</disk>
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/>
<source protocol='gluster' name='gv0/5d99af76-33b5-47d8-99da-1f32413c7bb0/images/011ab08e-71af-4d5b-a6a8-9b843a10329e/3f71d6c7-9b6d-4872-abc6-01a2b3329656'>
<host name='glusterfs.mydomain.de'/>
</source>
[...]
All hosts have vdsm-gluster gluster installed:
[root@microcloud21 libvirt]# yum list installed | grep vdsm-*

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