libvirt users - Jan 2016 - libvirt + ceph rbd will hang

hi all：

         I use openstack icehouse

and libvirt 0.10 version

use the quem+ceph to save vm disk

 

when I do serval operation for example migrate vm、snapshot vm

the libvirtd will be hang

 

I guess whether the ceph rbd will cause this error
