[pve-devel] [PATCH v2 qemu-server 0/9] RFC: sdn: add ipam support

[Alexandre Derumier <aderumier@odiso.com>]

Hi,

This is an RFC to implement ipam support on qemu-server.

This don't change the cloud-init current working.

As I need to manage pending ip registration configuration, to follow the pending netX interfaces.

I have added ip,ip6,gw,gw6 field to netX interfaces options. (same than LXC).

(as current ipconfigX pending, is pending cloudinit generation)


so the workflow is:

--> update netX=...,ip=.... 
   --> ip is registered as pending
         --> hotplug/coldplug succesful
               ---> pending ip replace current conf oldip
                       ---->the ip set in cloudinit pending ipconfigX
                            ------> cloudinit regeneration
                                 ---> ipconfigX is remove from pending

As documentation said than ipconfigX is for cloudinit config,
I think it could be ok.

Some users could use the sdn features without cloudinit(allow some subnets only, and autogenerate firewall ipfilter).

Also, for ipam, I need bridge && mac from the netX, and ip need to follow pending states of the nic.

Changelog v2:

- rebase on last master / proxmox7
- fix handling errors when multiple nics are hotplugged at same time
- keep ip address in ipam if snapshots reference it
- only update dns when pending ip is apply (need new pve-network patch)
- implement snapshot rollback/delete
- implement vm create/destroy


todo : implement backup restore
