Actually, VMWare has two drivers, one is ESXDriver and the other is
VCDriver.

When using ESXDrvier, one nova compute can only manage one ESX host, but
ESXDriver do not support some advanced features such as live migration,
resize etc. And this driver has been deprecated.

We are now talking about VCDriver which will talk to vCenter via wsdl API
and the  VCDriver is intend to support all VM operations, but we need some
enhancement to make VCDriver can work well for some advacend features such
as live migration.
