[libvirt-users] Libvirt and Glusterfs

[Pierre-Gilles Mialon]

Hi,

On a Fedora 18, I try to launch a VM with QEMU-GlusterFS native integration.

I have enable fedora-virt-preview repo, and gluster-alpha3 repo.

Below the list of installed package :
glusterfs-3.4.0-0.3.alpha3.fc18.x86_64

qemu-system-arm-1.4.1-2.fc18.x86_64
qemu-system-x86-1.4.1-2.fc18.x86_64

I have recompiled Qemu with –enable-glusterfs .

Here the content of my /etc/glusterfs/glusterd.vol

volume management
    type mgmt/glusterd
    option working-directory /var/lib/glusterd
    option transport-type socket
    option transport.socket.nodelay on
    option transport.socket.keepalive-time 10
    option transport.socket.keepalive-interval 2
    option transport.socket.read-fail-log off
    option rpc-auth.ports.insecure yes
    option rpc-auth-allow-insecure on
end-volume


I have defined the following line in my domain.xml

    <disk type='network' device='disk'>
      <driver name='qemu' cache='none'/>
      <source protocol='gluster' name='gv1/test.img'>
        <host name='127.0.0.1' transport='tcp' />
      </source>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05'
function='0x0'/>
    </disk>

but launching qemu with commant line work great :

file=gluster://

virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0


Am I missing something ?
