I am just starting testing. Everything looks good right up until I try and start an instance. Then, it just starts and dies. I get the no valid host error. If I run nova hypervisor-stats, I get ALL zeros. But, more curiously, when I do a nova hypervisor-list nothing comes up at all?

So, upon more troubleshooting...I find this in nova-compute log (and it is of course not running)..

2013-06-20 15:28:28.028 20464 INFO nova.virt.driver [-] Loading compute driver 'libvirt.LibvirtDriver'
2013-06-20 15:28:28.067 20464 ERROR nova.virt.driver [-] 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"])

Anyone have any suggestions BEFORE I rebuild this box for the 3rd time this week?

I am lost at this point, although I did find an issue if anyone out there is having SLOW dashboard issues and I will be posting to any I can find today.

Thanks for any help you can...
