Hello, we have a Dell m1000e Bladecenter with some blades and in the handbook it says something about "Virtualization technology" which can be switched to on. Would this bring any advantages with Xen? We have a couple of VM running on the blades. thx for help Heiko _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Not only will this bring advantages, but it is the only way you can get Xen to run HVMs - any O/S that isn''t Xen-aware, like Microsoft Windows (wow, is that really the only one left these days??). So, if you plan to run Windows or some of the earlier versions of Solaris on Xen, you''ll definitely need to switch this on. If you''re only going to be running Xen kernels for Linux, Solaris, BSD, etc., then you don''t need it, but you won''t lose anything by turning it on. -Nick>>> On 2008/03/25 at 05:21, Heiko <rupertt@gmail.com> wrote:Hello, we have a Dell m1000e Bladecenter with some blades and in the handbook it says something about "Virtualization technology" which can be switched to on.

Anything with a Linux 2.4 kernel, for example, is likely to require full virtualization. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

When you say Solaris is para-virtualized don''t you mean OpenSolaris? I tried to get Solaris 10 to work in PV mode but failed miserably, but OpenSolaris works easily. --Apoorva _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Yes, I did mean OpenSolaris, which I''m assuming will eventually make it back into mainline Solaris... -Nick>>> On Tue, Mar 25, 2008 at 5:15 PM, "Apoorva Kulkarni" <apoorva1911@gmail.com> wrote:On Tue, Mar 25, 2008 at 4:03 PM, Nico Kadel-Garcia <nkadel@gmail.com> wrote: Nick Couchman wrote:> Not only will this bring advantages, but it is the only way you can > get Xen to run HVMs - any O/S that isn''t Xen-aware, like Microsoft > Windows (wow, is that really the only one left these days??).
