You're thinking of high-availability, which registers the vmx file of the VM to a physical server that isn't dead, then powers the VM back on. Whereas vMotion is either a cold or live-migration of the VM + memory state (if the VM is powered down, there is no memory state to migrate).
It's been awhile since I tested this but I had played around this on Cisco 5108 blade servers. We'd test vMotion by pulling out blades during testing to see the VM migrated. Isn't that what vMotion is for.
