VIO 3 networks on VXLAN

Hello,

Deployed VIO 3 with NSX in Lab

when creating provider networks, i noticed that name of network must much portgroup name

this works just fine

Next, i try to create network based on VXLAN

so I create a logical switch with name internal and use portgroup as type of network and specify something like virtualwire-8

Horizon permits creation of network, however, instance creation fails if that new network is used

it seems that nova looks for internal portgroup(which is not exist) and fails once it not found

Any ideas how to overcome this ?
