(For anyone who wasn't on the PlanetLab-Xen list, just briefly, we're
discussing running a PlanetLab node inside a Xen domain. The current
blocker is kexec support inside a Xen domain. If you want more info you
can check the archives from the PlanetLab-Xen list.)

Ok, well I gave kexec a go, and sure enough, it didn't work. I'll see if
there's a newer version of the patch, since the one I'm using is at
least a month old and it appeared to still be under development then.
But if anyone actually knows anything about it that would be great to
know :)

In the short term, it might be possible to replace kexec with a
mechanism to shutdown the domain and start another using the parameters
requested by kexec.
