[Xen-devel] [BUG] Only 1 VCPU is detected in Xen 4.1 - "A valid RSDP was not found"

[John Mok <a9121431@xxxxxxxxx>]

Hi,

I tried to install Xen 4.1 using new Intel Atom C2758, which has 8
cores and VT-x feature. However, only 1 CPU was available in Dom0 and
SMP disabled.

When booted to normal kernel 3.2 without Xen, all 8 cores were available.

Thanks a lot.
