Live Migration with AMD & Microsoft

Watch this live migration demonstration using Hyper-V in Microsoft Windows Server 2008 R2. The migration is between "Barcleona" Quad-Core AMD Opteron and "Shanghai" Quad-Core AMD Opteron based systems.

This would have been better if you weren't playing a video that *could* theoretically have been cached from disk and into memory already by the time the migration happened. Love the tech and R2 as a whole, but the demo failed to provide adequate proof. :)

Think we may be in violent agreement, Akordated.

The AMD-Red Hat demo is meant to be a proof of concept only. I don't think either party represented that this was a finished solution that could be productized and sold.

This is why I say no smoke and mirrors. If claims were made beyond this, I would certainly agree with you on the smoke and mirrors statement.

FUNNY! No smoke and mirrors? You can't live migrate between different vendors because of hardware incompatabilities. Things will just "work" until you one application fails, which it invariably will because the instruction sets and the characteristics of each instruction is different. I would like to see a realistic demo, not some stupid AMD-RedHat publicity stunt.

[Matt Kimball]

It can't be done in today's environment, johiidk, but there si a way to mask the instruction sets that would allow. Believe Red Hat was the company that demonstrated a proof of concept. No smoke and mirrrors - actually worked.

Have you watched this video? It's a live migration from AMD to AMD. This isn't some stunt.

You can cold-migrate between Intel and AMD but not Live Migrate. You can VMotion between all generations of Opteron be it dual, quad, or six core. You can't do that with all gens of Intel

[Matt Kimball]

There is a different video on YouTube that shows live migration from an Intel box to an AMD box. It was done. It can be done. *That* video was done to ruffle feathers - it was to show what could be done.

*This* video does not demonstrate live migration across vendors. This video demonstrates Hyper-V live migration across AMD processor generations.

[akordated]

You can't live migrate from AMD to Intel because you can't do it from Intel to AMD. If you can do one, you can do the other. The truth is you can't do either. This video is just to ruffle feathers. Has no affect on reality.

[akordated]

So the same logic applies the other way. You can't live migrate from Intel to AMD too. This is video just a stunt. You can't have these in production

[Matt Kimball]

Different instruction sets. But, AMD has actually demonstrated a proof of concept - live migrating an Intel based VM to an AMD platform. As you can imagine, Intel was not too happy.
