Hello Nixon, We tried a similar scenario in the past with keepalived to float the IPs across instances. As long as you’re saying to CloudStack that the IP is allocated somewhere, this should be okay and you should be able to float the IPs between or among instances on your own. Is there anything else you would want to achieve like NAT for example?

Yes, I did try that, and the interface would get an additional IP address. However, we are unable to add the same IP to another VM as a secondary. For instance, in case of a DB cluster VM 1 (DB1) with nic ens3 and IP 10.1.1.6 VM 2 (DB2) with nic ens3 and IP 10.1.1.7 For these two virtual machines, I need to set up a floating IP with pacemaker, such as 10.1.1.8. As a result, my application can connect to this floating IP, and the pacemaker will display the IP address on VM2 (DB2) in the event that VM1 goes down. Hope you got my senario With Regards, Nixon Varghese On Tue, Jul 2, 2024 at 11:57 AM Jithin Raju <[email protected]> wrote: > Hi Nixon, > > Could you try acquiring the required IP as a secondary IP address in one > of the instances?
