Public bug reported:

Cisco Nexus VXLAN setup:
     Compute-1 and Compute-2 connect to N9K-1, Compute-3 and Controller+Network node connect to N9K-2.

Issue: when launch multiple VMs simultaneously, the Nexus switch is not
configured properly.  Sometimes missing the VLAN, or the VNI mapping.
It is not consistent.  Sometimes happen to the 1st switch, sometimes to
the 2nd switch.

Steps to reproduce:
1. Fresh reboot both N9K switches.
2. At Controller CLI, launch 10 VMs each with 3 interfaces in different subnet.
3. Check the switches configuration.
