True. But it tests the _hypervisor_ livepatch code.

I am thinking that this discussion about "oh, but livepatch-build tools don't 
work b/c"
is well <shrug> sucks but should never block an release as the core
livepatch functionality is OK.

Irrespective of that the testing of livepatch-build tools should be in osstest,
granted nobody has taken a step in this - but is somebody signing up for it?
