Localhost migration does work in most combinations in our tests.  It
was only recently added and there are a few teething troubles with it
so I don't have a full slate of results.

It doesn't work at all with libxl because it's not implemented.

2.6.18 doesn't boot on my test hardware so I'm just building it, not
running it.  So I haven't reproduced your test, which explains the
different results.
