If anyone is interested in configuring Xen on Gentoo with minimal settings,
I'm willing to send the necessary files and settings to get at least PV-
domains running.
I've got it working inside a Virtual Box VM, which makes testing HVMs
impossible, but I don't see any reason why that shouldn't work. It's just a
matter of enabling the support.
One of the goals of the Xentoo-project is to find out the absolute minimum
needed to get it to run.
For now, libvirt and virtmanager should be usable as a management tool (along
with some others that are around)
If you're looking for an out-of-the-box solution, XCP or XenServer sounds like
a good starting point to me.
