Re: [Xen-devel] xen can only detect one core of multiple cores cpu

Yes, booting ubuntu directly can see 6 cores. The dmesg results from native ubuntu: http://paste.ubuntu.com/13553870/
BIOS setting is http://snag.gy/v8XeJ.jpg  http://snag.gy/hSnDs.jpg  http://snag.gy/pQz7o.jpg http://snag.gy/6TdqJ.jpg
This is the grub.cfg http://paste.ubuntu.com/13553514/

I'm using a  Intel 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?
