These tests cover a number of scenarios where we care about

Hi David,
since I'm finally introducing test suite coverage for this,
it would be great if you could double-check that the values
we're going to test against actually make sense :)
You can see the configuration for the guests above: they
both have 1 GiB of RAM and use KVM, but one of the two is
using device assignment. The sizes are in bytes, so that's
~20 MiB for the basic guest and ~2 GiB for the one using
device assignment.
For reference, the code doing the calculation is
https://github.com/libvirt/libvirt/blob/9b93c4c26483308371aae3ae30bf5536c...
