Thanks for this. I haven't gone through all of the tests in there yet, 
but noticed (yesterday) a couple of them were personality file compute 
API tests, which I thought was strange. Do we have any idea where the 
time is being spent there? I assume it must be something with ssh 
validation to try and read injected files off the guest. I need to dig 
into this one a bit more because by default, file injection is disabled 
in the libvirt driver so I'm not even sure how these are running (or 
really doing anything useful). Given we have deprecated personality 
files in the compute API [1] I would definitely mark those as slow tests 
so we can still run them but don't care about them as much.
