Folks ! I finally got my quad-core Xeon working and I am testing Xen in Fedora 6. I partitioned the box into Dom0 and a guest Dom with 2 CPU each. When I run a multithreaded program in guest domain I see CPU utilization (in virt-manager) go upto 50% (out of 4 CPUs). Is guest SMP working then ? But I have read that guest can be Uniprocessors only. Is that correct ? thanks for your help, -Sanjay -- View this message in context: http://www.nabble.com/Xen-DomU-Guest-SMP---Working---tf2877449.html#a8042158 Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Nice hardware too, glad to hear Xen works well on it.

Of course, you have to be running a guest OS that supports Xen''s SMP interface, but the Linux port does.

Yes, its the stock Xen that came with Fedora 6. I just picked Virtualization and it automatically setup Dom0 with Xen kernel. So adding a guest using virt-manager was no problem once you got past "horribly broken" mouse problem (very painful). Other than that I am very impressed with the ease of use. I am pleasantly surprise to see that Xen SMP guest works in Xen 3. I looked at some very recent posts that seemed to indicate it was still UP. May be its turned on in unstable tree that Fedora derives from. thanks for the good news. -Sanjay Excellent! Nice hardware too, glad to hear Xen works well on it. Is that the stock FC6 Xen package?

I think that restriction may have been lifted in 3.0.4 now... or if not I imagine it''ll be doable in 3.0.5. Someone can probably fill in more details...
