Re: [pve-devel] GUI for DHCP
I guess this would only make sense if qemu people accept such patches upstream.

Re: [pve-devel] GUI for DHCP
Another more clean way, could be configure a dhcp relay on my routeur (which are gateway for each vlan), the forward dhcp requests to the proxmox hosts (define all proxmox hosts in dhcp relay) (In this case, all proxmox hosts need to be able to reply to all dhcp requests of all vms) But the problem is that work only with 1cluster. I also seems that IPv6 SLAAC solves the problem. With RDNSS you can get IPv6 address, gateway, and DNS server. And this does not have any problems with VLANs, because it is handled by the router.

From my understanding it seems like dnsmasq is binding unconditionally
to every interface?
Should it not only bind to selected interfaces?
An idea for the need to have assigned an IP for an interface: If user
chooses to have DHCP for a specific interface we create an alias
interface which listens on broadcast and first IP in subnet for DHCP
requests only. This also means first IP in subnet must be reserved if
users wants to have DHCP support.
