Ceilometer compute namespace drivers not loading

[Miguel Alejandro Cantu]

When running "ceilometer-polling --polling-namespace compute" none of the drivers from the 'ceilometer.poll.compute' namespace are loaded. This results in none of the compute meters being produced.
After doing some digging(by adding log messages pretty much everywhere), it seems that stevedore can't load the libvirt module here[1], which is causing this callback function to execute[2].

ceilometer-polling.log after LOG.debug(exc) was added, which prints out the exception:
http://paste.openstack.org/show/480719/

I'm really scratching my head here and could use some help. Maybe the libvirt driver can't be loaded because it runs on a different venv?? I'm not so sure. Any advice would be appreciated!
