Re: Utility of PV on non-obsolete hardware

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	hello.  Below is a config file for bringing up an HVM domU host under
xen3.3 with a serial console.  I've used this with FreeBSD and NetBSD-4.x.
I have FreeBSD-11.x running  with this setup, so although the xen
installation is quite old, I'm able to run modern versions of domU guests.
Will this help get some documentation going?
