How many iterations does this normally have to go through to get fresh
data?
6 - 7 iterations - seems pretty consistent in my testing.
I suppose it's a reasonable band-aid for now.
In the future, most of these tests will use the provider to create the
guest (not virsh), so I think this problem will go away on its own in time.
Although, we'll want to have some tests that use virsh, just to make
sure the providers handle guests created outside of the providers. So
we'll need this (or something like this) in those cases.
