Identifying the VM host for all Virtual Machines

We are preparing a licensing report for a budget planning meeting and I have been asked by management to create a report which:

1. Identifies all the Hyper-V host in my domain.

2. Identifies the guest VMs on each Hyper-V host

3. Identifies the type of server OS running (either Enterprise or Data Center).

Has anyone create a similar Powershell script for this information? or what would you advise?

Thanks
