Kea-dhcp on host


I have been trying to migrate the dhcp server on the host from dnsmasq to kea but failed in so far as the lxc-guest would not receive an address from kea. From the kea logs it is apparent that no dhcp requests is received.

With kea listening globally the logs however produced:

[kea-dhcp4.dhcpsrv/28994] DHCPSRV_OPEN_SOCKET_FAIL failed to open socket: the interface vethDU6QB4 is down or has no usable IPv4 addresses configured

Whilst dnsmasq is working and this perhaps being an issue of kea (and not lxc) I was wondering though whether someone has got kea-dhcp working with lxc containers, and if so how?
