Public bug reported:

The vmware_nsx NSX|V and DVS plugins enable a admin to create a provide
network that points to an existing portgroup.

One is uanble to spin up and instance on these networks.

The trace is as follows:

This is due to the fact that the validation for the network selection is
done according the the network UUID (which is the name of the port
group). In the case of importing a existing port group this actually
needs to be the name of the portgroup.

The NSX|V and DVS plugins enforce that the name of the network needs to
match the name of the existing port group
