Well, you have two options:
1) If your hardware supports VT, you can boot this in a Xen HVM domU (fully virtualized).  To do this, you need to make sure that the initrd images in the Linux partition are set up correctly to support the PIIX IDE/ATA chipset and that your root and fstab entries use the correct device.
2) If you can install a Xen domU kernel into the Linux partition install, you can boot the installs in a PV domU with the PV kernel.  RH9 may take some work to get going - not sure what the latest status of RH9 domU support is.  This will get you better performance on the domUs, but requires a little more effort in getting the correct kernels installed.

I have two Linux Operation Systems installed on my computer,a RHEL and a RH9. The two linux are installed in real partitions .
The problem is:
  If I install Xen in RHEL, can I make RH9 a Guest DomainU and boot it using Xen? How?

Thank you !
