small note for future - we could re-evaluate possibility of testing this
driver on gates with VMs when qemu version with BMC support (plus
[python-]libvirt support for such functionality) is generally available in
In this case we could stop using virtualbmc and use qemu natively. Not sure
how valuable such testing would be, but it won't for sure be pyghmi talking
