OpenStack L3 load balancer

Is it possible to implement an L3 load balancer in open stack?

I want to load balance incoming traffic to a Virtual IP across multiple VMs based on source IP. Does any of the OpenStack neutron plugin have this feature?

If not, is there any other Linux based approach that I could use to implement this feature?

HA proxy and OpenStack LBaaS is not suitable for me as there are L4 load balancers and handles only TCP and UDP traffic.

Yes, it is possible to do L3 load-balancing in OpenStack. OpenStack has a project for this called Octavia (Load-Balancer-as-a-service).

  1. Install OpenStack Octavia using the info in: https://docs.openstack.org/octavia/latest/contributor/guides/dev-quick-start.html

    https://github.com/openstack/octavia

  2. Add the following in /etc/neutron/neutron_lbaas.conf:

    service_provider = LOADBALANCERV2:Octavia:neutron_lbaas.drivers.octavia.driver.OctaviaDriver:default

  3. Add the following in /etc/neutron/neutron.conf:

    [octavia]
base_url=http://<IP address of OpenStack controller node>:9876

  4. Add the following in /etc/octavia/octavia.conf:

    [neutron]
service_name = <name of the neutron service in the keystone catalog>
endpoint = <custom neutron endpoint if override is necessary>

  5. Sample configuration file for Octavia is at https://github.com/openstack/octavia/blob/master/etc/octavia.conf.
