No Migration After vShield Endpoint was implemented !

I have implemented vShield Endpoint successfully,

but when I tried to megrate vm from one host to another,

It gives me this note: (currently connected network interface

uses network vmservice-vshield-pg which is a virtual intanet).

when I check the Network of two hosts involves in the configuraiton,

I found that vShield has created three virtual simple switches on both of them,

Although I'm using vDS only !,,, I don't know why vshield has created them!!

however, I need to perform vm Hot migration, what's the cause and the solution

for this issue.

Please know, I am using vSphere 5.1, vShield 5.1 (vCNS).

I have to hosts in this cluster with HA & DRS are enabled.

Please check the images for the Error Note, and the Network Configuration on Host 1 & Host 2.
