Xen 3.2 is in the final stages of preparation. We (Xen upstream) are
planning to provide binary packages for Centos 5.1, amongs others.
I've merged the patches and so on from xen-3.0.3-41.centos5.i386.rpm
with a recent xen-unstable RC tip (16701:8922a1469284). With a bit of
effort I have managed to get a set of packages which appear to be able
to work at least in my simple `does this function at all' test.
I'm mentioning it here so that you can have a look at what I've done
and comment on it. We'll probably be making official upstream rpms
very soon after the Xen 3.2 release, which we hope will be early next
week. Please send me feedback either here on-list or privately.
Most of the useful patches from 3.0.3-41.centos5 have been
incorporated upstream so I just deleted those from my srpm.
There were also a few changes which I have just dropped. In
particular, the RHEL5 package (and thus the Centos one too) is a
bizarre frankenxen containing a forward port of the 3.0 dom0 userland
tools to the Xen 3.1 hypervisor.
In my package I have included the hypervisor in the xen-*.rpm rather
than making a kernel package too. This is more in line with practice
upstream; dom0 kernel compatibility between the 3.1 and 3.2
hypervisors is good and the new hypervisor seems to work for me with
the Centos 5.1 2.6.18-53.el5xen kernel.
You can find the actual files here:
http://www.chiark.greenend.org.uk/~ijackson/xen-3.2-package-previews/centos5.1/
These packages should not be used for production - they're previews
and I may have made elementary packaging mistakes. Xen 3.2 is still
unreleased and in need of more testing.
Regards,
Ian.

I know I appreciate the effort you guys make to release these binaries
for the different platforms.
If I had only 2 wishes they would be, 1) try to make the install mimic
the distro's Xen path layout a little better, 2) provide 64-bit binaries...
Other then those two little points I have found the binaries pretty
stable.
Thanks,
-Ross

Ok, I gave it a whirl, the minor paths issue I mentioned earlier seems
to be fixed here, but the 'localtime' patch needs to be backported
(or forwardported in this case) as HVM clocks still only report time
in UTC.

Which localtime patch is that ? I don't see anything relevant in the
patchset for the package I was using as a basis. If you could provide
a reference I'd be happy to take a look. (Was it submitted upstream?)
Ian.

Actually I think it is functionality that is in the 3.0.3 versions of
xm and xend that upstream mashed up with the 3.1 kernel to make it's
package.
I believe that the 'localtime' option broke in either of those utilities
when the HVM clock was moved from qemu to the Xen kernel.
Unless the option to have the clock use the local time has changed...
