Hello to all! I have a problem with nova-compute daemon, start-up fails with following error:
2012-11-15 19:14:34 INFO nova.compute.manager [-] Loading compute driver 'libvirt.LibvirtDriver' 2012-11-15 19:14:34 ERROR nova.compute.manager [-] Unable to load the virtualization driver: Class LibvirtDriver cannot be found (['Traceback (most recent call last):\n', ' File "/usr/lib/python2.7/dist-packages/nova/openstack/common/importutils.py", line 31, in import_class\n return getattr(sys.modules[mod_str], class_str)\n', "AttributeError: 'module' object has no attribute 'LibvirtDriver'\n"]) My release is Folsom, running on Ubuntu Server 12.04 x86_64.

Or something else could prevent nova-compute to start? I did a lot of googling and I found the same question on several mailing lists and IRC chat logs, but no one gave any solution. I was hoping that changed over time and that someone could help me with this one. Thank you all in advance. Best regards.
