Well, he did say from PV to HVM, I can't think of anything PV that can't
be made to play nicely with a NFS root. But there very well may be.

You can install grub and stuff prior to starting the process via the PV
guests OS packaging mechanism which also gives you the appropriate
native kernel and modules in most cases, commonly people forget about
the modules and wonder why it won't boot.

I guess my method could be a nightmare if circumstances were just right,
but I've yet to run into those circumstances even with older kernels.
I find the reverse, that NFS booting works well only when the circumstances are just right. I've attempted to NFS boot in distributions that didn't support it natively, and have had *serious* problems with it. (SuSE: it had to be SuSE......)
