Hi A question about Xen port. I just read the Christian Limpach mini howto about xen: http://mail-index.netbsd.org/port-xen/2004/04/07/0000.html I have some questions: - I need always a linux host for boot DOM0 ? If it''s true, why ? - I can use a NetBSD host for do it ? - I can use only NetBSD for use Xen in DOM0 and the others domains ?

If it''s true, why ?yes, because the NetBSD port doesn''t support access to the hardware. You would also not be able to start other domains because the port doesn''t support dom0 operations. Finally you''d need network/block backend drivers so that other domains could access network/block devices.> - I can use a NetBSD host for do it ? > - I can use only NetBSD for use Xen in DOM0 and the others domains ?Not sure what you''re asking. christian ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Hi Christian ! Then the netbsd-xen port only enable to build a kernel and start netbsd domains >=1 ? How I can install a "normal" netbsd 2 system in a DOM>=1 ? Thanks in advance. roberto On Thu, Dec 16, 2004 at 12:29:27PM +0000, Christian Limpach wrote:> On Thu, Dec 16, 2004 at 09:20:12AM -0300, Roberto Pereyra wrote: > > - I need always a linux host for boot DOM0 ?
