[pve-devel] RFC: sdn: add ip management (IPAM -DHCP) ideas

I think at vm creation time, or nic hotplug/unplug.
the ipam api is called, return free ip address, and we write somewhere in vm config the ip address.
(for nic hotplug/unplug, we need to handle ipam removal on config revert)

Like this, user can generate cloudinit if needed with the ip address, can do custom firewall rules, we could generate dhcp... before starting the vm.

Ok, that makes sense now. 

Do you want to allocate IPs on VM creation time, or VM start time?
