But that will be a discussion for another series ;).
something to also consider is HA permissions: https://bugzilla.proxmox.com/show_bug.cgi?id=4597 e.g., who is supposed to define (affinity or other) rules, who sees them, what if there are conflicts, .. what about conflicting requests? let's say we have a set of 5 VMs that should run on the same node, but one is requested to be migrated to node A, and a second one to node B? if a user doesn't see the rules for lack of privileges this could get rather confusing behaviour wise in the end? what about things like VMs X and Y needing to run together, but Z not being allowed to run together with Y, and user A that only "sees" X requesting X to be migrated to the node where Z is currently running? _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
