Hi All, We are planning to support the XEN on IBM PowerPC 970MP based blade which is running SUSE 10 Operating System. We have couple of queries regarding support XEN: 1. Is there any readily available patch for SUSE 10(as a guest) to support paravertualization? 2. Is there any porting required for XEN source for IBM 970MP? 3. Is it support both paravertualization and Hypervisor ?, If yes, Is this hypervisor source is available for IBM 970MP? Thanks, Ashok _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Xen consists of a hypervisor (Virtual Machine Monitor), and various tools and utilities to control that hypervisor.

Thanks Jon, I think support is there on PPC as google took me to: http://xen.xensource.com/files/xs0106_xen_on_powerpc.pdf Regards, Ashok -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Jonathan Ervine Sent: Wednesday, October 17, 2007 6:50 AM To: xen-users@lists.xensource.com Subject: Re: [Xen-users] Xen for IBM 970MP On Tuesday 16 October 2007 12:38:34 Ashok Hegde wrote:> Hi All, > > > > We are planning to support the XEN on IBM PowerPC 970MP based blade > which is running SUSE 10 Operating System.As far as I''m aware, Xen virtualisation is a technology for Intel and AMD class processors and therefore not applicable to PowerPC architectures.

I''m not aware of any project internally to implement Xen on the SUSE PowerPC release either, so I can only imagine the hassle that would be involved in patching a PPC release of SUSE to get it to work with Xen. The presentation you linked to also has links to the Xen wiki for PPC: http://wiki.xensource.com/xenwiki/XenPPC?action=show&redirect=Xen%2FPPC It would indicate that the project is still live, and has completed a lot of the code to make Xen functional (not all committed upstream though), but I wouldn''t be comfortable introducing it to a production environment. If you''re thinking of using it with SLES 10, you''ll be miles away from a supportable configuration too :-) Jon> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Jonathan > Ervine Sent: Wednesday, October 17, 2007 6:50 AM > To: xen-users@lists.xensource.com > Subject: Re: [Xen-users] Xen for IBM 970MP > > On Tuesday 16 October 2007 12:38:34 Ashok Hegde wrote: > > Hi All, > > > > > > > > We are planning to support the XEN on IBM PowerPC 970MP based blade > > which is running SUSE 10 Operating System. > > As far as I''m aware, Xen virtualisation is a technology for Intel and > AMD class processors and therefore not applicable to PowerPC > architectures.

The PPC970 blades were one of the hardware platforms they were intending to support. I''m not aware of the code being production ready, though.> The presentation you linked to also has links to the Xen wiki for PPC: > http://wiki.xensource.com/xenwiki/XenPPC?action=show&redirect=Xen%2FPPC > > It would indicate that the project is still live, and has completed a > lot of the code to make Xen functional (not all committed upstream > though), but I wouldn''t be comfortable introducing it to a production > environment.

If and when it is ready, I imagine that IBM will probably start selling products based around it! In the meantime I suspect you''ll need another solution. Maybe you could look at using something like OpenVZ or VServers to partition up a single Linux system? Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals!
