Only 1 core is recognized in Dom0 - "A valid RSDP was not found"
Hi, I tried to use Xen 4.1.4 on Debian Wheezy running on Intel Atom C2758 hardware. Only 1 VCPU was available in Dom0. When I booted to normal kernel 3.2.0 without Xen, all 8 cores were available. I hope someone could point me how to fix the Xen code to make all 8 cores available to Dom0. Thank you, John Mok === Begin of xm dmesg == (XEN) ACPI Error (tbxfroot-0220): A valid RSDP was not found [20070126] (XEN) System RAM: 32759MB (33545412kB) (XEN) Domain heap initialised (XEN) Table is not found!
