While we do cache the hosts's capabilities in self._caps in the libvirt Host object, if we happen to fist call get_capabilities() with some of our dedicated CPUs offline, libvirt erroneously reports them as being on socket 0 regardless of their real socket. We would then cache that topology, thus breaking pretty much all of our NUMA accounting. To fix this, this patch makes sure to call get_capabilities() immediately upon host init, and to power up all our dedicated CPUs before doing so. That way, we cache their real socket ID. For testing, because we don't really want to implement a libvirt bug in our Python libvirt fixture, we make due with a simple unit tests that asserts that init_host() has powered on the correct CPUs.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
Developers
