For a Training IIS MS brings a Hyper-V and 2 VMs inhouse.
We want to run the hyper-v ontop of Vsphere 4.1.
Is this possible.
I know that we need newest Server HArdware with Nehalem-EX / EP or AMD Magny Coures.
Well, you can run vSphere on top of vSphere and its support for test and dev.
I doubt MS are going to support Hyper-V on vSphere but nonetheless i suspect it would work. Never seen it done though.
Actually is not possible to virtualize Hyper-V or Xen over vSphere (or other virtualization layer).
As written you can have nesterd vSphere, but with some limitations.
Well, you can run vpshere 4.1 as a Virtual Machine on a vsphere 4.1 but again you need to re-configure the vsphere VM.
Similarly you can run Hyper-V on top of vsphere 4.1 but it would be just another Virtual machine running on a host and as stated above, i doubt it can provide all of the virtualization features
anyway, please have a look at this. It might help you in someway.
