Just to note, I was going to get an Ultra 20 M2 but the lead time of delivery was too long. So I put together a quick Athlon X2 (Windsor) with a Gigabyte NForce 590SLI motherboard. I did a quick test with Xenoppix [1] (Knoppix and Xen) and HVM worked like charm. This runs Knoppix in a HVM domain. I''ll be doing some further testing with Windows once I''ve installed everything. Note its important that if you get an Athlon that you check the model. Only the Windsor (dual core) and Orleans (not dual core) do AMD-V. It can be very confusing with the AMD ratings and the GHz ratings.

Only the Windsor (dual core) and Orleans (not dual core) do AMD-V. It can be very confusing with the AMD ratings and the GHz ratings. Whilst it may be confusing when you look at the model numbers for the processor, it is very easy to tell from the Socket which works with AMD-V and which doesn''t. All Socket AM2 processors except Sempron has AMD-V. Another universal key is that any processor that uses DDR2 (again, except Sempron) has AMD-V. This is of course the same thing as the socket key, since they are tied together - the new socket is introduced to match the DDR2 memory interface [or at least, there are different sockets for the different types of memory controller]. Similarly, the new Opteron product has a new socket (Socket F) and DDR2 memory controller, and has AMD-V. Mobile product is the only one available as X2 (Dual Core), and again DDR2 is a key to AMD-V. So in summary: Any AMD processort (except Sempron) that uses DDR2 memory will have AMD-V. Note that although the AMD-V technology is in the same product that introduces DDR2, there''s no tie between the two other than the fact that they are introduced in the same product version. -- Mats Nicholas [1] http://unit.aist.go.jp/itri/knoppix/xen/index-en.htm _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I understand what you are saying about the AM2 socket and AMD-V. Regardless because of previous product on the market I still found it difficult when putting a system together to make sure I had the right processor. The only way I could be sure I was right, was making the model (ADO...) of the processor against the list on wikipedia. Descriptions of processors sometimes aren''t sufficently clear on webstores.

Agreed. Unfortunately, it''s hard to satisfy all aspects of marketing, technical descriptions, etc, etc. It would be confusing to a lot of people if we (AMD) started using different product names and/or numbering for processors that for all intents and purposes (besided virtualization) are equal. Then we''d get LOTS of calls to the tech-supprot asking if the new Super-Athlon64 4000+ X2 would run the same software as the older Athlon64 4000+ X2... We don''t really need that... ;-) It should be clear from the Webstore which socket the processor applies to, even if they don''t supply any further information at all...

Given Intel seem to have only one desktop chipset that supports VT, might be an interest point of difference for marketing. Yes, AMD''s processors have full support for AMD-V inside the processor, and chipset choice will make absolutely no difference to availability of the AMD-V features. I suspect somehow that the reason Intel requires certain chipsets for the VT functionality is that there is interaction between the memory controller and the VT functionality - but I don''t know this, I''m just gueesing - there is however little OTHER reason for this to be the case... -- Mats Nicholas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
