Manages information about the host OS and hypervisor.
This class encapsulates a connection to the libvirt
daemon and provides certain higher level APIs around
the raw libvirt API. These APIs are then used by all
the other libvirt related classes

This is a native thread which runs the default

any incoming async events from libvirtd and queues
them for later dispatch. This thread is only

driver.queue_event method. In particular any use
of logging is forbidden, since it will confuse
