Guys I have successfully deployed vCloud Director 5.1 along with the vShield Manager and have deployed a few vApps and VCDNI networks etc... All seems to be OK there.
The issue I'm having is I want to test VXLAN. When I go to prepare a cluster, I see a new portgroup appear on the DVswitch "vxw-vmknicPg-dvs.....blah" however no vmkernel port is created on the port group. From what I've read, a vmk port should be created and its on this interface that DHCP waits for an address. I'm unable to manually create a vmk port on the newly created VXLAN port group as I get the following error message:
In the end I need to unprepare the cluster to remove the portgroup. I have rebooted the hosts, vSM and vCenter. This has made no difference.
