I've try your patch, but can't boot the vm.
[root@yinyin qemu-glusterfs]# virsh create gluster-libvirt.xml
错误：从 gluster-libvirt.xml 创建域失败
错误：Unable to read from monitor: Connection reset by peer
the libvirt build the qemu/gluster command correctly, the qemu-kvm try to run, but faile after a while, that cause the libvirt monitor connect failed.
the /var/libvirt/qemu/gluster-vm.log follow:

I can boot the vm with the command:

my question:
1.what's the libvirt hook funciton? could it affect the qemu-kvm command?
2.It's hard to debug the qemu-kvm progress from libvirt, I try to hang the glusterd for a moment, then to gdb the qemu-kvm, do your have better methods?

This patchset provides support for Gluster protocol based network disks.
It is based on the proposed gluster support in Qemu on qemu-devel:
http://lists.gnu.org/archive/html/qemu-devel/2012-08/msg01539.html
Just to be clear, that qemu feature didn't make the deadline for 1.2,
right ? I don't think we can add support at the libvirt level until
the patches are commited in QEmu, but that doesn't prevent reviewing
them in advance . Right now we are in freeze for 0.10.0,
VDSM patch @ http://gerrit.ovirt.org/#/c/6856/
An early feedback would help me, especially on the xml spec posted here. My VDSM patch
depends on it.
thanx,
