[Xen-users] VCPUs question

[Songtao Liu <songtao.liu@xxxxxxxx>]

Hi List,

still the question about VCPUs.
When I set VCPU >= 2, then I can not boot the guest.(the guest kernel is SMP)
Guest is 2.6.20-1.2952.fc6

How can I make it run with 2 VCPU :( ???

here is some other info: cpuinfo and xen configuration file.
