Do we need to fake anything in the tests directory to ensure that the
tests never probe the system, but always treat things as no power
management available? I'm worried that running the testsuite as root on
a Dom0 host might cause spurious test failures, although I have not yet
tested that. I guess we can deal with the fallout later if it turns out
to be a problem in practice.

For qemu, you skipped the warning for qemu:///session (ie. geteuid() was
non-zero). Should we do the same for lxc and uml, or are these
hypervisors only ever useful as root?
