Hi all,
I am using devstack on Ubuntu 12.04 server with kvm hypervisor. I upgraded
libvirt from 0.9.8 to 1.2.1. Due to which I can not create instance and
hypervisor is not getting connected.
waqas@server2:~$ nova hypervisor-list
+----+---------------------+
| ID | Hypervisor hostname |

Looking in the screens, I found following errors in n-cpu screen.
