I'm using a ÂIntel E5-2603 v3 @ 1.60GHz CPU of 6 cores. However, the dom0 can only find one core. here are some information that may helps in analyzing.

From `xl dmesg`

(XEN) ACPI Error (tbxfroot-0218): A valid RSDP was not found [20070126]
(XEN) SMP motherboard not detected.

Xen cannot find any ACPI tables, and finds no secondary CPUs. As a knock-on effect, dom0 only gets one.

How is your BIOS configured? Does booting Linux natively work?
