Hi Pasi,
I realized that Fedora 10 32-bit anaconda installer does not install PAE kernel after mounting the guest disk image file. I mounted the guest disk image file using losetup and kpartx which adds device nodes to /dev/mapper. I examined the /boot directory after mounting the guest disk image file and found no PAE vmlinuz and initrd.
Still using the mounted Fedora 10 32-bit guest disk image file, I changed root to the guest disk filesystems and attempted to install the PAE kernel. Then I modified menu.lst to boot the PAE kernel. After modifying the grub configuration of the guest domain, I un-mounted the guest filesystem.
I proceeded to boot the F10 32-bit guest, since I changed to PAE kernel. It is able to boot now (since the PAE kernel is xen-aware) but then it complains cannot mount /dev/root. Probably something to do with the PAE initrd file.

Fedora 10 installer has a bug, as a default it installs non-PAE kernel for
xen domU. You need to use a kickstart script (like this) to fix it:
http://pasik.reaktio.net/fedora/f10-xen-domu-ks.cfg

The important lines being:

-kernel
kernel-PAE

(Fedora 10 and Fedora 11 default kernels are compiled with pv_ops Xen domU
support enabled, so there's no need for separate kernel-xen with these distros).

Fedora 11 doesn't have that installer bug, so it installs right
out-of-the-box as Xen domU.

What's the error you get when you start the guest after installation?
Please paste the "xm log" as text.

I don't have any problems with CentOS 5.3 dom0.
