[Xen-users] OpenBSD as XEN domU on Linux dom0 without HVM
I think the title says it all. I''m wondering about installing OpenBSD as DomU onto my XEN-3 dom0 that''s running Gentoo/Linux (x86). My CPU doesn''t support any VT so it should run only para-virtualizing the devices. Has anyone any experience with that? Is it possible? How are the performances? I read about poor performance (but the thread was dated 2008 so I guess something has changed so far). Thank you. -- Fabiano Francesconi [GPG key: 0x81E53461] _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I do not see any indication that OpenBSD has a Xen-aware kernel available. It looks like running OpenBSD on Xen requires HVM. -Nick>>> On 2010/04/19 at 10:18, Fabiano Francesconi <fabiano.francesconi@gmail.com>wrote:> I think the title says it all. > > I''m wondering about installing OpenBSD as DomU onto my XEN-3 dom0 that''s > running Gentoo/Linux (x86). > > My CPU doesn''t support any VT so it should run only para-virtualizing > the devices. > > Has anyone any experience with that?

I guess there''s no way to boot a BSD kernel without HVM, then :( -- Fabiano Francesconi [GPG key: 0x81E53461] _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

NetBSD also supports it: http://www.netbsd.org/ports/xen/howto.html#netbsd-domU And here''s the FreeBSD Xen wiki: http://wiki.freebsd.org/FreeBSD/Xen -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.
