Opteron 250 and amd-v

I've a server with 2 AMD Opteron 250 cpu's. AMD's website seems to
indicate that it should support amd-v but I beg to differ. A
DMIDECODE on my Linux server shows no indication of Hardware
Virtualization being available for the Opteron 250. I'm a little
****ed about this as I bought this server thinking that that CPU
supported Hardware Virtualization and now I'm thinking I've been
duped. Any insight would be very helpful. FWIW, the BIOS on the
machine is AMI 1.71 and there is nowhere in that BIOS that allows me
to enable/disable virtualization.

Thanks.

None of the Socket 940 Opteron 1xx, 2xx and 8xx support AMD-V. For
virtualization you need Socket F Opterons (1xxx, 2xxx, 8xxx).

I don't know much about the Opteron. Maybe this will help.

Or maybe you need a bios upgrade.

Dunno about your hardware, but there are reports of BIOSes which
intentionally disable CPU virtualization support (and it can't be turned
back on).

Supposedly the idea is that the maker then charges more for a
hardware-identical model where the BIOS _doesn't_ do that.

I don't know any actual names though.

A BIOS upgrade won't help in this case as the Opteron 250 does not
support AMD-V.
