Just upgraded to build 9100 and am trying out the Hyper-V monitoring feature.  Hyper-V host is running Windows Server 2008 R2 w/Hyper-V.  It has 5 Guest VMs and WMI is enabled an working.  When I discover the host, it adds all the VMs properly and all seems well.  However, many metrics inside the VM do not work, such as:

- Memory usage

- CPU usage

- vNIC usage

..which makes the monitoring somewhat pointless.  

Also, the CPU core IDs for the host monitoring are out of order -- that is, there is Core 0,1,11,12,13,16,17 etc, no rhyme or reason as to why it wasn't just sequential (the host is a 2 x 6-core machine)
