Hi guys, This afternoon I suddenly find that there are quite a lot of nova py27 unit test failures on Jenkins, like http://logs.openstack.org/15/62815/5/gate/gate-nova-python27/82d5d52/console.html. It seems to me that the registerCloseCallback method is not available any more in virConnect class. I'm not sure whether this is caused by a new version of libvirt python binding? Any comments? -Lianhao
