I am porting OpenMosix on top of Xen. However, the stable release of openMosix is based on Linux Kernel 2.4(They are trying to port it to kernel 2.6). So, how can I create Linux Kernel 2.4 (i.e., Fedora 1) guest OS on top of CentOS 4.3? I wonder why Xen didn''t support the lower kernel version such as 2.4 kernel. There is some open sources based on kernel 2.4. Thanks for your help in advance! -Yuzhong _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Xen 2.0.x supports/ed the 2.4 kernel, but the current one doesn''t. I guess you could run a HVM guest (unmodified source) on a VT/SVM machine, but I doubt that this is what you''re after. As to why 2.4 isn''t supported, I''ll let someone else answer that... -- Mats ________________________________ From: xen-devel-bounces@lists.xensource.com [mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of Yuzhong Sun Sent: 19 May 2006 14:46 To: xen-devel@lists.xensource.com Subject: [Xen-devel] Kernel 2.4?

In fact, we are trying to build a virtual cluster on a set of VMs on top of Xen. OpenMosix or Open SSI are available open-source cluster management tools. Do you know the better guys?

Do you know the better guys?sure. You can build virtual bproc clusters. bproc is a much lighter weight system than opemmosix or openssi. We run 12,000 CPUs of cluster here at LANL with bproc. It''s very nice. If you are interested I can get you a writeup on how we did this. The work was done about 18 months ago. for more info on bproc, see clustermatic.org. The next-gen bproc we are doing, called xcpu, is even lighter weight than bproc, and runs on any kernel, though for full capability it is good to have kernels >=2.6.14 ron _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
