Github user nlivens commented on the pull request: https://github.com/apache/cloudstack/pull/756#issuecomment-137720078 @wilderrodrigues, this change doesn't remove the Netscaler support for VPCs from the UI. The actual Public Load Balancer provider is derived from the VPC offering, and not from this extra field "Public Load Balancer Provider". So, this field has no use at all since it's completely ignored.
