Hello Jayapal, I have told the eth3 and eth4 before since the CS4.0.2, just do know there they come from.
In this thread , and another thread, reported the odd eth3 eth4 too. So may find out why the eth3 eth4 come from, it may help to resolve this problem. I have tried remove the V-router and create a new one before, but no luck to get the guest VM work. I will try delete the v-router now. Thank you.
