vmware Labs has released vCenter XVP Manager and Converter, their first stab into management of non-VMware virtualized environments. vCenter XVP Manager allows you to use the vSphere Client to manage Hyper-V Server 2008 hosts and their associated virtual machines, it also allows you to easily migrate those Hyper-V based virtual machines into VMware virtual machines.
The installation is pretty simple, you first install a server piece that could very well be installed on your vCenter Server, then you install a XVP Manager Plug-in into your vSphere Client which is done via the vSphere Client Plug-in Manager.__
This product is currently only listed as a vmware Labs Fling, which means that it is not guaranteed that it will continue beyond it’s 1.0 Technical Preview status, but if people like it and push vmware for this type of functionality we may very well see it embedded within the core vCenter Server product.
