qemu native glusterfs integration with libvirt. It's all working well
from the qemu side, but libvirt fails to start a domain with a gluster

Hi Vijay,

Thanks for
your answer. 
I did reset the files and tried to attach the device
using: virsh attach-device test /tmp/gluster_disk.xml
<disk
type='network' device='disk'>
 <driver name='qemu' type='raw'
cache='none'/>
 <source protocol='gluster' name='vol0/test0.img'>
 <host
name='127.0.0.1' transport='tcp' />
 </source>
 <target dev='vdb'
bus='virtio'/>
 <address type='pci' domain='0x0000' bus='0x00'
slot='0x07' function='0x0'/>
 </disk>

# virsh attach-device test
/tmp/gluster_disk.xml 
error: Failed to attach device from
/tmp/gluster_disk.xml
error: operation failed: open disk image file
failed

Sadly, nothing reported in ...bricks/*.log

Thanks,
Olivier
