Kernel 2.4?

Kernel 2.4?

[Yuzhong Sun]

[-- Attachment #1.1: Type: text/plain, Size: 427 bytes --]

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!

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...

There's lots more work to port 2.4 kernels to Xen-3, than to finish 2.6
openmosix. Now you could just use Xen-2, which support 2.4 kernels.
Patching 2.4 kernel on Xen2 with openmosix should be trivial.

I wouldn't count openmosix-2.4 as a good source here ...

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?

 

Thanks

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
