Hi Qasim,

Replied inline to your non-triple-o specific related questions.
Also regarding your following email, any specific reason you try to use
LBaaSv1?
I highly recommend that you go with LBaaSv2 (you may still choose haproxy
if you wish), since LBaaSv1 is deprecated[1] and will be removed[2]
sometime in the future.

I have not tested this myself, but I suspect you will run into some
difficulties. The VIP for your loadbalancer is actually a neutron port. a
port contains a hostname in its binding information.
