Thank you, what if I replace one of the processors with a FPGA co-processor. This will just look like a PCI device for the BIOS during bootup. How can I force xen to use the memory behind the FPGA for DomU guests, if created (Instead of the master memory behind the CPU where both xen abd Dom0 is loaded from). regards, Dinesh C _________________________________________________________________ No Harvard, No Oxford.
