Hello,

I am planning/studying to build one HA cluster to manage LXC containers with live migration.

My containers will have multiple public static IPs assigned.

In case of failure of one node containers will be migrated to a healthy one, but I do not understand how networking (IP addressing) works in this case.

Who will route IPs to healthy node ?

Are there any good practices for HA in networking too?

Thank you.

Hello,

I am back on this topic after a long time.

Yes I know I will have to manually migrate containers.

It is not clear to me how networking and public IPs are managed.

Will Proxmox do routing/forwarding between nodes or I have to manage it with other software like Openvswitch?

Thank you
 
Proxmox doesnt reroute anything. IF you have L2 connection (bridge or similar) LXC send an arp broadcast when the container start, and your switch/router know where is located.

You can create L2 domain with OpenVswithc, but this is different layer of networking, not connecting to Proxmox and LXC migration directly.
