vmotion network config error

I am having difficulty doing a vmotion migration, or, more accurately, a relocation via vmotion. I am using the vcenter web client. I am getting the error that the "migrations failed because the ESX host were not able to connect over the vmotion network."

From one ESX host, (we'll call it ESX A)I can see that it can ping the target ESX host (ESX B) vmotion IP but it can only ping it if I specify the vmk port for mgmt, not vmotion, on ESX A.

Below vmk1 is the vmotion port IP and vmk0 is the mgmt port IP.  vmotion is only enabled on

vmk1. But, since I CAN ping the target host vmotion port IP (192.168.175.40) using vmk0, I'm thinking I may can just enable vmotion on the mgmt port, and it could work. (And disable vmotion on the vmotion port) My main concern with this is freaking out the host if I enable vmotion on the mgmt port as I don't want to bring down this production system.

Or, is there a way to correct the routing to where vmk1 can ping then ultimately vmotion over the vmotion network like it should work?

Can you please show your vmkernel ports on the hosts along with the network information on the switches?
