I currently have a cluster of 4 hp dl380 g5's with intel xeon processors. I was looking at ordering a new Dell with 4 Opteron Quad processors. I know i cannot vmotion between these hosts. But is there any issue with shuting the vm down on the intel server. Migrating it to the amd and booting it back up. I guess the guest os will see the processor change. Has anyone done this and had any issues.
