Hi Caitlin,

I need multiple ip address for my Haproxy server.

Here is my senario

I have already running Haproxy Server virtual machine for web load
balancing on vSphare with 45 public ip address. We are running 45 diffrent
websites and we required diffrent ips for each webiste.

We have 6 webservers with only local ip address. These 6 webservers holding
all 45 websites. Haproxy just forward the request to local webservers
accorindg to DNS.

Now I want the same kind of Haproxy setup on openstack

Best Regards,

Umar
