[coyotos-dev] Xen port

[Jakub Witkowski]

Hello,


In my humble opinion, Xen can be made rock solid with just a little
tweaking, at least on amd64/emt-64. I don't know much about Fedora
packaged version, but from my experience the only good way to use it is
to use source.

The only real problem is that current upstream won't work on Pentium-M
based systems, as it requires PAE extension which, for some reason, is
missing from this family of CPUs.

Personally, I would love to see Coyotos port for Xen; I think the
development could quite benefit from it, as the effort could be directed
to where it really matters while leaving the bare metal issues to Linux
kernel.

Jakub.
