Hi, I followed you instructions, I've build and installed
xen-3.2.0-0xs and xen-libs-3.2.0-0xs.
Now I get this error when I execute xm list:

This looks like you didn't change the grub.conf to specify
the Xen 3.2 hypervisor as opposed to the stock Xen 3.1
hypervisor that the RH/CentOS Xen kernels are set to use
by default.

Oh. Hmmph. RedHat uses some cuteness in current versions of 'grubby' and RPM to auto-install the Xen kernels in grub.conf. When I was working with RHEL 4, it took some extra work to get them into grub.conf. But RHEL 5 has it incorporated into their RPM's. You might take a look at the RHEL versus Xensource SRPM's and look for the differences.

I'd like the Xensource RPM's to do this automatically, as well.

Well actually, RH bundles the Xen hypervisor right with the Xen
kernel in EL5, so that's how they handle it.

??? Distributing it or not, the RHEL packages automatically install the grub.conf entries, using 'grubby'. At last look, the Xen kernels compiled from SRPM or provided as binaries did not, and took extra manual steps to configure. Does the most recent version address this yet?
