I''m still trying to figure out how to get my Xen installation on a 34-CPU machine (8 quad cores) to recognize more than one CPU per socket. It seems to default to one CPU per socket on this machine. Win2003ServerEnterprise will support 8 quad cores (32 CPUs) in a native install, but I can''t fathom why it won''t when installed under Xen (OpenSuSE11.0). Thanks for any help!

Thank you very much for the reply, Todd! :-) I tried one of those setting lines in one of those links a couple weeks ago, but maybe haven''t found the right config file to put it in? I''ll give those others a try... It seems like this should be a very common problem/solution with all the cheap three- and quad-cores out there - if indeed Xen automatically defaults to a single cpu per socket everyone would be :-( ! (I haven''t found any non-programmers who have actually cracked that code in those links for setting the cpu''s per socket). Happy New Year!
