As most people know, vmotion between CPU's with different instructions can be problematic and there are apparently a couple of different approaches to overcome the incompatibility. The first approach: Tell virtual center to not test for CPU compatibility. This is NOT supported, and from what I've read VMWare support will be upset if you open a service request after doing this.

So why has the datacenter come out of its anonymity, and is suddenly filling
