I have a Gigabyte GA-M61SME-S2 motherboard with an Athlon 64 X2 4600+

The "svm" flag is present in /proc/cpuinfo, but "xm dmesg" contains:

  (XEN) AMD SVM Extension is disabled in BIOS.

I have carefully gone through the BIOS setup options, and I don't see
anything relating to virtualization, HVM, SVM, AMD-V, etc.

See the thread "Xen AMD-V HVM" from a month or so ago. That was with a GA-M61P-S3. It seems to be a 'feature' of these gigabyte boards that they disable SVM and don't let you switch it on again.

The solution for that one was to downgrade to a version of the BIOS that didn't know how to switch SVM off. That might work for you.

Otherwise, avoid gigabyte boards for xen use.
