I have to create a system based on Xen virtualization. I entrust myself those who have experience in the field. What is the preferred distribution to install Xen hypervisor? Debian, CentOS, Fedora, Ubuntu? Installing a distribution on x86_64 Xen hypervisor (dom0), you can install a PV guest with x86 architecture (domU), not HVM? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Not sure about Debian, but I know Ubuntu isn''t ideal for Xen any more because of the presence of GRUB2 - the new boot loader doesn''t support passing certain command lines and the current multiboot implementation breaks the method Xen uses to load the Dom0 kernel - you can''t use Ubuntu 9.10 Server with Xen. Fedora doesn''t ship with a working Xen Dom0 kernel in its repositories, though I believe it may be possible to compile one yourself. Personally, I use CentOS as our Dom0 (and DomU, mostly) OS and have run into very few issues. Installing Xen is as simple as using Yum...it''s an ideal place to start, plus the community is huge so it''s easy to diagnose issues and get advice from fellow users. Hope this helps, Luke.

Current Debian version (Lenny) works great with Xen (3.2 packaged). So, it cab be an alternative to CentOS :) Regards, Olivier XO Project http://xen-orchestra.com On Mon, Mar 1, 2010 at 9:21 AM, David Markey <admin@dmarkey.com> wrote:> I would say CentOS plus the gitco repo(http://www.gitco.de/repo/) > > On 1 March 2010 08:09, Luke Carrier <luke.carrier@xinos.org> wrote: >> >> Not sure about Debian, but I know Ubuntu isn’t ideal for Xen any more >> because of the presence of GRUB2 – the new boot loader doesn’t support >> passing certain command lines and the current multiboot implementation >> breaks the method Xen uses to load the Dom0 kernel – you can’t use Ubuntu >> 9.10 Server with Xen.

No problems till now. And yes, you can use 32bit domUs on 64bit dom0 (even in paravirt mode, each domU can have its own kernel). _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
The documentation for CentOS 5 shows a set of borders between architecture host and guest at this link: http://centos.org/docs/5/html/5.2/Virtualization/chap-Virtualization-Compatibility_of_host_and_guest_combinations.html So who is right?

That''s a personal preference - there is not "right" answer. It depends on who you ask. I like SUSE Linux Enterprise Server, myself, because it''s stable and well-Supported. Unfortunately SLES lags behind in terms of features and versions, so with SLES 10 I''m still on Xen 3.2.x, and on SLES11 I''m on 3.3.x. There are several features in 3.4.x that are very, very, nice, and that I miss by using SLES. Fedora and openSuSE have fairly recent versions of Xen included, and I imagine Ubuntu does, as well. Because CentOS follows the RHEL product, Xen isn''t also the most up-to-date on that platform, either. Really, it comes down to what distribution you''re comfortable with, and which one provides versions and features that you require. In answer to your second question, yes, an x86_64 dom0 can support 32-bit (x86) and 64-bit (x86_64) domUs, both PV and HVM. The types of domUs you can run does not depend on your distribution or dom0 (as long as you have the correct tools installed), but more depends on your hardware - all hardware supports PV guests on Xen, but HVM guests on Xen require VT support to be included and enabled with the hardware. -Nick>>> On 2010/02/28 at 16:21, Paolo Rivetti <natecult@me.com> wrote: > I have to create a system based on Xen virtualization.
