What is it?
VMware vCenter Multi-Hypervisor Manager is a component that enables support for managing heterogeneous hypervisors when used in conjunction with VMware vCenter Server v5.1 and vSphere Client 5.1.
It is not available for the vSphere Web Client, with this in mind I am not sure what the roadmap for this will be post 5.1 seeing as they are EOL the desktop client.
