Hello,
i have a problem with the full virtualisation (hardware virtualisation) of XEN (using Intel VT) for a virtual Windows 7 machine.
I use a Intel E8500 (Core 2 Duo) Processor on a ASUS P5Q. Both are supporting VT.
At the moment a have running Windows 7 on VirtualBox (running on openSuse 11.1 x86_64) with activated VT Support, so it is not a problem of the BIOS or the hardware.
On my normal openSuse 11.1 installation i have checked the VT support with cat /proc/cpuinfo. I can see the important flag “vmx” and “smx”.
But when i reboot with XEN installation on openSuse 11.1 x86_64, i doesn’t have VT support (missing flags “vmx” and “smx”). Also i can see differences by “cpu MHZ”, “siblings” and “cpu cores”.
After booting the actual XEN Live CD v2.0 for x86_64 i have the same problem.
Has somebody a solution for the problem?
