Hi, I'm trying to use 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 drive or attach a drive. I have exactly the same error as this person: https://www.redhat.com/archives/libvirt-users/2013-April/msg00204.html I use qemu 1.5.1 with glusterfs 3.4 beta 4 and libvirt 1.0.6.

Do you observe errors in the logs from gluster bricks that make up vol0? 
Brick logs are available at /var/log/glusterfs/bricks.

Thanks,

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
