Does this mean what I think it means, namely PAE is supported?
Yes it does.

If so, is there any change that has to get made in the xen.cfg
of the client virtual machine to enable it when the machine starts?


You just need to put the module in the kernel. The rest is made automagically. Miguel

Thanks

It has been previously stated on this list that RHEL5 supports PAE
(with Xen 3.0.3).
How do we tell, given the Red Hat RPMS that go on with a default
"virtualization" install, are those PAE or not?
(I am trying to run 32-bit PAE domU's on a 64-bit xen 3.1.0 host
and I am wondering if the stock red hat kernel-xen-2.6.18 with
xen 3.0.3 is good enough to get the xen virtual client instance up
and then upgrade to xen 3.1 from there.)
Most kernels, and most certainly the RPM published kernels, contain a /boot/config-[kernel-version] file. You can read that.
