The vultr driver seems reasonable. FWIW, I'm looking at feasibility of writing a driver for oVirt[1] using its Python SDK[2][3]. The tests against mock is a bit discouraging - as I was about to use the Python SDK, I'm unsure how much effort it'd take. Need to look at it further. I guess I'll develop something, test it first, then think of how to implement the tests. Thanks again, Y.
