Changes

* VMware ESX Server host to VMware ESX Server host

At the time of writing, only VMware ESX Server's VMotion feature supports live migration whereby there is no interruption of service as the virtual machine is migrated. Current versions of both Hyper-V and Virtual Server only support static migration, where the virtual machine state is saved during the migration process and then restored on the destination host causing a loss of service. Live migration is scheduled for inclusion in future Hyper-V versions.
