[pve-devel] [PATCH v3 pve-network 03/12] sdn: dhcp: only consider subnets that have dhcp-range configured

[Stefan Lendl]

From: Stefan Hanreich <s.hanreich at proxmox.com>

If DHCP is enabled on a zone with subnets, but no subnet has a
dhcp-range configured, then starting a VM will fail because no IP can
be allocated. This patch fixes this by only considering subnets that
have a dhcp-range configured and only failing if there is at least one
subnet with a dhcp-range configured.
