Hi all,

First of all I apologize because I am not very fluent in English.

I am new to the forum and in the world of OpenStack/cloud computing. I have many ask about it:

1) The load balancer must be used only in active/active mode? Example: If i want realized a services API High availability with redundancy in active/passive mode there is no need the load balancer because there is only one node active , while there is need to install Pacemaker and Corosync/hearthbeat for monitoring activity of nodes. Is it right?

2) By docs OpenStack it is not possible to create multiple L3 agent in active-active configuration but only in active-passive while DHCP agents can run in active-active configuration, why?

3) Why is not possible create a multi-hosting network with Neutron component? If is possible , how?

4) How do implement i Compute Node high availability? there is nothing talk about it. Can i have 2 compute nodes and they are load balancing by a Load balancer? what happen if there is a failure?

Thank you in advance for your answer. I am looking forward to hearing from you.
