[pve-devel] [PATCH v8 pve-network 00/25] sdn: add subnets management

[Alexandre Derumier]

This patch series add basic subnets managements.

Subnets will be use for multiple things:
- defined gateway ip on vnets
- enable snat on a subnet
- add cloudnit|dhcp default network configs (gateway, static routes, nameservers,searchdomain,....)
- add ipam management. (ip registrations to external ipam, for vm|ct ip management)
- add dns registration. (reverse dns for subnet, and searchdomain regisration in external dns like powerdns )
- ...


Already implemented:

- gateway option is implemented:

It's currently replace ip management on vnets for layer3 plugins,
through the option "gateway".

If the option gateway is defined, for layer3 plugins (evpn && simple),
the ip will be used for the vnet.

A vnet can have multiple subnets, with multiples ipv4/ipv6.

- ipam
- dns registration


Changelog v2:

- add ipams plugins. Currently netbox && phpipam.
- the subnet && the subnet gateway are registered to ipam
- add/del/find_next_free ip are implemented, so it should be easy to use them in qemu && lxc config.

Changelog v3:

- add an internal ipam plugin

Changelog v4:

- fix pveipam plugin find_free_ip
- detect ipv4/ipv6 in find_free_ip

Changelog v5:

- add vnets add_ip,del_ip,... should be ok for use in lxc/qemuserver

Changelog v6:

- add dns plugins
- internal ipam fixes
- rework vnet-subnet association
- fixes && cleanup

Changelog v7:

- add snat to simple|evpn plugin
- cleanup subnet options
- fix reversedns

Changelog v8:

- move subnet api to /sdn/vnet/<vnet>/subnet
- make ipam non optionnal && use pve ipam as default
- don't allow subnets on vlanaware vnet
- fixes && cleanup
