Has anyone yet figured out what it would take to make Xen run on top of the Red Hat Enterprise Linux 6 beta? We are heavily invested in Xen under RHEL5 (actually a redhat clone) distribution, but already the xen kernel they are shipping with update 4 and 5 is shaky and has bugs which they don''t seem to be in a hurry to fix. Basically I am wondering if Redhat 6 is just going to have benign neglect and ignore Xen, or if there is going to be stuff built into the OS which actively mitigates against Xen in favor of KVM.

So, if you insist on using RHEL, be advised that you''ll likely end up having a much easier time using KVM, as well. If you don''t mind using KVM, you should be okay. I''m sure you can get Xen to run on RHEL6, but, if you want a Supported/Integrated build of Xen, you''ll need to switch to one of the distributions that still packages and Supports Xen (Debian, Ubuntu, Gentoo, SLES/SuSE, etc.). I doubt RedHat will actually put anything into their O/S to prevent you from using Xen, but they''re definitely going to make it easier to use KVM (their product) on RHEL than Xen. -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

So, as far as we have a functional dom0 (whatever distro we choose), we would be able to upgrade our domUs to RHEL6 without big problems.

RedHat and derivatives (Scientific Linux) are only distros approved at my facility Unless someone comes up with a way to do an alternative kernel/hypervisor that can run a dom0 in a RedHat OS environment (such as was the case in xen 3.0.2-> xen 3.0.4 days) , there will be a lot of us that are forced out of the Xen business, which is of course exactly RedHat''s plan.

One option may be to consider Fedora as they appear to be working to add Xen back in the next release: http://www.networkworld.com/community/node/61745 There are also Oracle Linux and CentOS that may do something about including Xen.

As part of the Unbreakable Linux Support program, Oracle supports virtualization that is included with Oracle Enterprise Linux 5. Please note that Oracle products are not certified to run in that environment. Any customer who wants to deploy Oracle products in a virtual environment should use Oracle VM, and subscribe to Oracle VM support. So if the Hypervisor is completely different then OEL they''re pulling off some pretty neat magic. OEL has tracked RHEL release for release from 4.4 to 5.5 so unless you believe in celestial teapots we can assume it might continue to do so. Does anyone actually use Oracle VM so we can get a qualified answer as to what it IS running? I''m downloading both now as I''m curious. What makes the most sense is OEL6 will track RHEL6 and they''ll go through the trouble of getting Xen in Dom0 since they now have 3 VM technologies surrounding Xen. However, they could just move all their management tools to KVM and dump Xen as well.

I''m downloading both now as I''m curious.The hypervisor on Oracle VM presently announces itself as 3.4.0. There are, as you might imagine, patches on top of that. It really iis dramatically different. The critical thing (in part of what I snipped out) is that Oracle applications are certified to run on guests in OracleVM, but not as guests in the Xen implementation that''s in OEL5 (or RHEL5), regardless as to whether it''s Xen or KVM.> > What makes the most sense is OEL6 will track RHEL6 and they''ll go > through the trouble of getting Xen in Dom0 since they now have 3 VM > technologies surrounding Xen.

Hi,> Does anyone actually use Oracle VM so we can get a qualified answer as to > what it IS running? I''m downloading both now as I''m curious.Oracle VM runs Xen 3.4.0 as already stated. I figured a new release will follow shortly to bring in things like tmem compression, default use directed balloning (dom0 manages ram sharing / paging out idle VMs), bkltap2 and such. It is very close to normal Xen on the first look, but has quite a few modifications for performance / stability (yes, really, not just in the whitepapers)> What makes the most sense is OEL6 will track RHEL6 and they''ll go through > the trouble of getting Xen in Dom0 since they now have 3 VM technologies > surrounding Xen.

Since Sun xVM is Xen it would make sense to merge these two technologies.
