Запуск dnsmasq в контейнере докеров на Debian - check_dhcp игнорирует dnsmasq

Я тестирую конфигурацию для моего dnsmasq DHCP на моей машине Virtualbox Debian. На производстве я хочу, чтобы dnsmasq предоставлял статические IP-адреса гостевым системам, работающим через qemu + libvirt + openvswitch (тот, который я рассмотрел, они работают через докер, и они работают)

конфигурация dnsmasq:

# Tried both eth0 and br0 for an interface - more about it near bottom
interface=br0
domain-needed
bogus-priv
no-resolv
local=/mydomain.io/
no-poll
no-hosts
domain=mydomain.io
dhcp-range=192.168.1.129,192.168.1.254,255.255.255.128,192.168.1.255,12h
dhcp-option=3
log-queries
log-dhcp

При подключении к br0 с interface = br0 после команды check_dhcp I ' м не попадает даже

dnsmasq-dhcp: no address range available for DHCP request via eth0

... в логах. В отличие от того, когда dnsmasq привязан к eth0 Как будто мой dnsmasq игнорируется, и я получаю ответ от docker dhcp-сервера.

И последнее, но не менее важное, мой route -n
