To loosen the live-migration constraints, Sunnyvale, Calif.-based AMD released a white paper disclosing details about AMD-V Extended Migration, a feature dating back to the first-generation Opteron processor that enables virtual machines to migrate between different versions of AMD processors.This is really a good thing, we are moving (rather) fast to a phase where the hardware vendors like Intel and AMD will be standing long before at the finish line with array of solutions for virtualization vendors. Some like VMware, with an obvious lead are already working hard to stay and keep up the pace with the hardware vendors, others have to wuickly adapt to the change ecosystem and develop their products accordingly. Either ways, customers and end-users will have loads of choice.
The need for migration ease
"Our customers are very interested in doing live migration because of the flexibility it provides," said Margaret Lewis, director of commercial solutions at AMD. "[AMD-V Extended Migration] is where the rubber meets the road. We've made this interface on the hardware end, but it is up to software to implement it."
AMD-V Extended Migration masks the differences between CPU generations, facilitating the safe live migration of virtual machines between servers running different generations of AMD processors. This includes existing single- and dual-core processors and all future AMD processor revisions, including the upcoming Barcelona quad-core AMD Opteron processor that is expected to be released Sept. 10.
And you know how comfortable the consumers are with "loads of choices", right? Anyways here's the coverage. Take a look at the whitepaper too!
