Is anyone working on porting the xensource-provided RHEL3 and RHEL4 Xen kernels to centOS? I've been poking the xensource-provided kernels, and they seem to work okay (though only on i686 platforms- I haven't gotten 'em to compile on x86_64) on my client's RHEL systems.
I host a bunch of CentOS Xen DomUs, so it would be really cool if I could re-use the "poke at the RHEL kernels" work for those CentOS domains as well- but from what I understand, I'm not supposed to just re-distribute the RHEL stuff without stripping out some stuff.

Feel free to submit a patch :)

Are you talking about RHELkernels or Xen supplied kernels that work for RHEL ?

I'm working on the x86_64 bit, but nobody here is particularly good with rpm, (and all of the RPM types I know are waay out of my price range) so I'm begging for free help instead :) Also, I'm a bit unsure as to what exactly has to be removed/changed to make it a CentOS kernel.
(Is there a framework in place for CentOS-specific bounties? I don't have a lot of money to blow, but sometimes even small amounts can help encourage people.)

Xen supplied kernels that apply the RHEL patches.

There is a "testing" RHEL4 kernel here that also includes a -xenU rpm (i686 and x86_64): http://people.redhat.com/~jbaron/rhel4/RPMS.kernel/

i suppose that implies we have a good chance of 4.5 shipping with Xen working out of the distro box!

you should have no issues using those on CentOS - have you tried rebuilding their src.rpm on x86_64 ?
( the fact that xensource do so much of their own work on CentOS should be a good indicator! )

Why is there porting required?
I thought that before CentOS pulled down stuff from RHEL, there was sanitization required for legal reasons. Is this not true of the kernel?

Sanitation is only required of the trademarked items like logos, artwork and branding, and is mostly for distribution. There's a difference between someone getting a package for personal use, and someone redistributing RH's work as their own.

And this isn't even RH's work, is it?

If you look at the centos kernel SRPM and compare it to the RHEL kernels you will see that the differences are minimal.
We add 2 kernel config files so that an i586 kernel will also build (does not affect the other kernels, just also builds i586). That also requires that allx86 includes the i586 arch.
We change a couple more items (the generated key that signs modules in named CentOS and not RedHat and requires 2 changes ... that is pretty much it).
If you point me at an SRPM that you want rebuilt, I would be glad to do the CentOS changes to it for you ....
The only other sanitizing is taken care of in the rebuild process ... where the Vendor tag of Red Hat, Inc. is removed.
Thanks, Johnny Hughes
Would someone please point out, then, where to look for instructions on implementing the Xen hypervisor on a CentOS 4.4 system? What about 4.3?

this is really the sort of question you want to take to the Xen lists, not here. this is centos-devel, and developer / distro related conversation is the only sorts welcome this side :)
you might also want to try the centos users list ( http://lists.centos.org/ for more details )

Will do, thanks.
