Hi Ross,
Thank you very much for the reply. It makes sense! So let me break
down the instructions:
1. rpm -i
http://bits.xensource.com/oss-xen/release/3.2.0/centos-5.1/xen-3.2.0-0xs.centos5.src.rpm
2> /dev/null
2. cd /usr/src/redhat/SOURCES ; wget
http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz
3. vi ../SPECS/xen.spec
i. Change "Version: 3.2.0" to "Version 3.2.1"
ii. Change "Source0: xen-3.2.0.tar.gz" to "Source0:
xen-3.2.1.tar.gz"
iii. Uncomment "# /usr/lib/xen/boot/hvmloader" to "/usr/lib/xen/boot/hvmloader".
(noted from previous threads to avoid rpmbuild error of unpackaged file)
4. yum -y install transfig texi2html tetex-latex gtk2-devel
libaio-devel gnutls-devel (dependencies needed for rpmbuild of
xen.spec in CentOS)
5. cd /usr/src/redhat/SPECS ; rpmbuild -ba ./xen.spec
6. Grab some coffee...
... and come back to this:

7. vi /etc/yum.conf and temporarily set "gpgcheck=0"
to "gpgcheck=1" since RPMs aren't signed.
8. cd /usr/src/redhat/RPMS/x86_64 ; yum -y install
xen-3.2.1-0xs.x86_64.rpm xen-libs-3.2.1-0xs.x86_64.rpm

9. vi /etc/yum.conf and set gpgcheck back to "gpgcheck=1".
Reboot.
xend won't start now with the following in /var/log/xen/xend.log

I did a quick peek in /usr/lib64/python2.4/site-packages/xen and all
the Python tools looks to be correct with 3.2.1.
Any ideas?

Don't use the xen kernel from xen.org just the hypervisor.
Download the 3.2 SRPM from xen.org, download the 3.2.1 tarball,
put the 3.2.1 tarball into the SOURCES directory, edit the
3.2 spec file and change the version to 3.2.1 then do an
rpmbuild of the spec.
This will produce RPMs that you can then substitute the CentOS
ones with and it won't compile the kernel just the hypervisor,
continue to use the CentOS supplied xen kernels with the
new hypervisor.
