Could you give some pointers as to how to compile the hypervisor as 64-bit??? I currently have a 32-bit setup but the hardware (CPU/MB/RAMetc) is 64-bit capable and I could just run 32-bit domUs I wanted to run more than a bare dom0 on the hardware for continutity .... but I am kind of free to try ANYTHING .... but I need to run stuff in Debian/32-bit ... So can you tell me how to compile a 64-bit xen.gz on my current Debian 32-bit PAE setup??? (the host needs to be up for certain other things although 24/7 is not an issue...) And if this is helpful to figure this out I am willing to spend some time to experiment ... to trying to make 32 bit built xen.gz run with gr= ub2 Let me know...
