vMotion fails after physical network changes

Products

• VMware vCenter Server

Issue/Introduction

• vMotion fails with the error "The vMotion failed because the destination host did not receive data from the source host on the vMotion network"
  
• The connectivity from source ESXi host to the destination host over vMotion kernel is not working. 
  

  [root@hostname:~] vmkping -I vmk2 x.x.x.x -S vmotion
  PING x.x.x.x (x.x.x.x): 56 data bytes

  --- x.x.x.x ping statistics ---
  3 packets transmitted, 0 packets received, 100% packet loss

Environment

vSphere ESXi
vSphere vCenter

Cause

After physical network changes, external physical network is not forwarding vmotion kernel traffic. 

Resolution

As a workaround tried the below steps:
1. Disabled vmotion service on the dedicated vmotion kernel. 
2. Enabled vmotion service over the Management kernel temporarily
