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

Excellent! Nice hardware too, glad to hear Xen works well on it. Is that the stock FC6 Xen package?

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 ?

Guests can be multiprocessor in Xen 3 - the uniprocessor restriction only applied in Xen 1 and Xen 2. Of course, you have to be running a guest OS that supports Xen's SMP interface, but the Linux port does.

Cheers,
Mark
