How do I enable communication to same ip address for multiple instances in Openstack?
Issue
- Alternate or secondary interface IP addresses do not function properly on Openstack instances.
- Virtual IP addresses do not function properly on Openstack instances.
- Keepalived Virtual IP addresses do not function properly on Openstack instances.
- An Openstack instance, by default, allows communication to only the mac address and ip address allocated for it by Nova/Neutron due to anti-spoofing rules. I have a requirement to configure additional virtual ips on the instance as ip alias for some clustering requirements which should float between multiple instances during fail over. How can I achieve this?
