Reads the KVPs for a certain VM from the Hyper-V host side via WMI. This is, of course, a Windows-only cmdlet.
Read-HostKVP -VMName [-Name] [-HostKVP]
If -Name is not specified, all KVPs are returned.
If the -HostKVP switch is present, the cmdlet will read the KVPs written to the VM by the host, not those transmitted from within the guest.
