[libvirt-users] libvirt live migrate problem

[lyz_pro]

 Hi 
The problem is after I successful live migrate a domain, the domain os become read-only.
and when I use qemu-img to show the disk info at node which domain current running ,
 the command return 'Permission denied'.
BUT, I can use qemu-img show the disk info at the previous node.

My Env:
two node, all install libvirt + kvm . use glusterfs as shared storage.
the libvirt/kvm version:
libvirt-0.10.2-29.el6_5.5.x86_64
qemu-kvm-0.12.1.2-2.415.el6_5.6.x86_64
qemu-img-0.12.1.2-2.415.el6_5.6.x86_64
glusterfs-3.4.1-3.el6.x86_64
