[Fedora-xen] VCPUs >=2 will lead to failure of guest boot

Tue Jul 3 14:56:17 UTC 2007

Hi,

As no one answer in list of xensource, I turn to here :)
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

When using Guest Winxp (VCPUs=2) it is OK.
How can I make it run with 2 VCPU :( ???

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

Thanks in advance
Songtao
