Virtual Machine Manager - cannot connect to VM network

[neonetman]

I have recently set up a Hyper-V cluster, and am trying to set up the logical networks in VMM. I have added a logical network, and and VM network, however when I try to connect a network card to the newly created VM network, it doesn't appear in the list.

 

I've tried copying settings from our existing cluster but am hitting a brick wall on it. Can anyone point me in the right direction?

 

Cheers
