Using xen-3.0.4-testing with an HVM booting the FC6 DVD on a Core2 Duo (i.e. 2 PCPU) on a 965 chipset
 
VCPU=17 – works
VCPU=20 – works (takes a very long time)
VCPU=24 – lockup (whole machine, yes I mean Dom0)
VCPU=31 – same
VCPU=32 – same

Have you worked out where it gets stuck? Do many-VCPU domU guests fare better?
