I've got a DL145g3 which is reporting svm support in /proc/cpuinfo:

but in "xm dmesg" i'm getting:

(XEN) AMD SVM Extension is disabled in BIOS.

I went through the trouble of commenting out the check in the xen kernel for the bios disable flag and basically lie to xen and it panics horribly on boot.

I've also flashed the bios to the latest version from the hp site as of today and gone through it hunting for anything to do with virtualization, but can't find an option there. I've also had someone else look for the option and he failed to find it as well.

At this point have I conclusively determined that the problem lies in HP's BIOS and not having anything to do with Xen?
