Also Citrix Xenserver (and XCP) has 64bit Xen hypervisor (xen.gz), with a 32bit dom0 Linux. So yes, it's possible to have 32bit dom0 with a 64bit hypervisor. You can run both 32bit and 64bit guests on it. -- Pasi > > > -------------------------------------------------------------------------- > > From: [email protected] > [mailto:[email protected]] On Behalf Of John Haxby > Sent: Wednesday, October 20, 2010 2:18 PM > To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list > Subject: Re: [rhelv5-list] XEN: 32 bit host 64 bit guest > > > > > > On 20 October 2010 11:42, Nick Lunt <[1][email protected]> > wrote: > > can't find a definitive answer so does anyone know if I can have a 64bit > guest on a 32bit XEN host server ? > > > > No, you can't.
