Open Stack

Hi all,

I install devstack in ubuntu12.04 and upgrade libvirt 0.9.8 to 1.2.2. The
libvirt version in my linux box is:

dujun at dujun-OptiPlex-3020:~/devstack$ virsh -v
1.2.2

And the error message in nova-cpu.log is such like that:

2014-12-03 11:00:13.007 ERROR nova.openstack.common.threadgroup [-]

I wonder why nova can't find the libvirt hypervisor since I have added

compute_driver = libvirt.LibvirtDriver

in /etc/nova/nova.conf.
