VDL2 overlay instance is not created on DVS before initializing VDL2 port or VDL2 IP interface.


Adding a new host to a DVS (distributed virtual switch) without setting the overlay property to this host, and then attempting to configure the VXLAN property to any distributed port on this host, will cause this error.


Create the overlay instance or configure the distributed port to the specific VXLAN.
