VirtualMachine.VirtualMachineRuntimeInfo.host is a MOR to the relevant Host object.
Though there is no direct way, the vmware.log of the VM logs the host the VM starts on (on a power on) and also logs which host it migrates to.
So the start of the log would contain
2013-01-02T15:02:33.787Z| vmx| I120: Hostname=xxxxx
and a migrate would contain
2013-01-02T15:02:34.463Z| vmx| I120: Migrate_Open: Restoring from <IP ADDRESS> with migration id 1357138953
