AMD-V Confusion

I'm setting up a second server for testing purposes to go with the Intel Atom 330 based server I have already.

I have been away from the AMD side of things for a while now & need to be clued in.

I chose AMD for my new build, ITX by the way, based on performance vs TDP, being an ITX build, and the presence of AMD-V.

On the Intel side it can be chore to know if a particular series of cpu supports the VT-X (AMD-V equivalent), feature. For example, earlier steppings of Intel's E4500 have VT-X support while more recent ones do not. Great chips like the E5xxx & E2xxx series do not have this feature enabled. This is contrary to AMD's VT support with virtually every X2 AM2 chip having this feature enabled.

On the Intel side of things, the motherboard's bios is also required to have VT-x support for the cpu that in turn has the feature enabled. Is this the same in the AMD world?

I am looking at the Zotac GF8200-C-E as an ITX board I am very interested in paired with a BE-2400 or 4850E (Pretty much the same chip). If anyone can confirm if this pair will allow full use of the AMD-v feature I would appreciate it very much.

Staying with the Mini ITX form factor may be seen by some as limiting & to some extent, with respect to motherboard choice, it is. I have had good results with my other Intel Atom 330 based serup , running Centos 5.2, but wish for the same form factor while investing in something more powerful yet efficient to run a few virtual servers as a proof of concept, learning tool and just plain fun.

Nope. All of the AM2 motherboards support V.

So then, unlike Intel, even the cheapest AM2 board has this support? In the Intel world it can be real hit or miss specially when it comes to Motherboards.

I haven't come across any AM2 motherboard that doesn't support virtualization.

You could always email the motherboard manufacturer.

Thanks a million for your quick reply.

I've already sent an email to Zotac.
