Code review comment for lp://qastaging/~rohitk/nova/libvirt_unittests

Hi William,

The issue was with the method test_map_to_instance_info that directly set the driver.InstanceInfo object to invalid test values and failed to unset during teardown. I have removed that code and modified the test to use only FakeVirtDomain object, and now the tests are passing without affecting test_virt_drivers tests. Thank you for pointing it out.

I have run the full suite and tests have passed. Please review.
