Hi I would like to install xen3.0 on an machine with 8GB ram. Does xen support 8GB? How much RAM will I have free to use for the DomU''s if I''m using a 128MB Dom0 for example. I also wonder if xen now works with jumbo frames on gigabit NICs.

If you give Dom0 128MB, the Xen kernel will take another few megabytes (perhaps around 20), the rest will be available to DomU''s to share as you see fit.> > I also wonder if xen now works with jumbo frames on gigabit NICs.Don''t know the answer to this. -- Mats> > Thanx > Tim > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
