I've been reading about how to make Xen show more then 16GB of ram and still support 32bit but so far all my attempts have not worked. FC7 was supposed to be able to run 32bit guests on its 64bit OS but because of a feature freeze, this was not possible even though it still says you can do it in the release notes which I find ridiculous. Anyway, someone told me if I replace the hypervisor with the 64bit counterpart, then I should be able to see more the 16GB of memory and be able to run 32bit guests. I did this by extracting the files from the 64bit RPM and replaced the xen.gz-2.6.20-2925.11.fc7 file with the one from the 64bit RPM and rebooted. The OS booted fine, however, when I tried running/installing a 32bit domU the console would not load or would lock up almost immediately. I can't think of anything else to try and any help would be greatly appreciated. thewird
