Redhat and AMD migrate VMs across CPUs

AMD and REDHAT have just done the so called impossible, and demonstrated VM live migration across CPU architectures. Not only that, they have demonstrated it across CPU vendors, potentially commoditising server  processors. Eeek!

The concept is simple, click a button, and your VM moves from one machine to the next. The execution for similar architectures has been done for ages, AMD can do it from E-Step Opterons to a promise of Magny Cours. Intel is a little more restrictive, but they can do it between iCore iNumber iNumberals as iwell.

The trick up till now has been to do the same thing between servers from different CPU vendors, it is the holy grail of virtualisation. Please note, there are about 37 holy grails of virtualisation at the moment, so this does not signal the end of days, just that the holy grail clock in Times Square dropped to 36.

If you look at the video here,you will see that they did it. Live migration while streaming HD video isn’t all that bad a trick mind you, but doing it between a Barcelona, Shanghai and Intel box is. 36 more of these, and we will be in great shape. original version is here.
