Can I assign a floating IP to multiple VMs (same IP address)?
I have a need to setup multiple addresses for the watchdog software in pgpool. Similar to running my own load balancer.
As a result, I have tried multiple methods of integrating the eth0:1 interface.. If I use static IP addresses then I get them on the VM, but cannot associate a floating IP with them properly. Only a dhcp address shows up in Horizon or nova list
After much beating up on this, I have been able to do the following: Get a DHCP address onto eth0 (different for each VM) and a floating address to each one. These are addressable from anywhere. I also was able to get a static address (same one) onto eth0:1 of both VMs. It is addressable from the inside only...
Now, the sticky part.....Since my software (pgpool) manages it's own VIP, I do not want to use the load balancer in Openstack. Plus, since this works as an active/passive type server, I obviously cannot have the servers bouncing to each other.
I am looking for a reference to assigning a floating IP to 2 different instances, or can it be tunneled to the address which is on both ?
