[lago-devel] Fwd: Lago/o-s-t VLAN/dnsmasq issue.

Hey, I suspect there's an issue where the current configuration of o-s-t (I've only tried basic-suite-4.0, but I guess it is not suite related), and more specifically dnsmasq's dhcp configuration under Lago/o-s-t (or otherwise) fails to serve VLAN interfaces. After successfully running basic-suite-4.0, I'm trying to call dhclient to serve eth0.600 on host0 (created in 005_network_by_label), which fails. DHCPDISCOVER(s) are reaching the bridge dnsmasq listen on, however no offers are being sent. A couple of things I've tried and the relevant conclusions: 1) After hotplugging a nic (eth1) on host0 via virsh (using the same source network/bridge), I've set a VLAN interface on top of it (eth1.600). Calling dhclient for eth1 worked; eth1.600 failed. I've tried this to rule out the cause being some configuration used in 005_network_by_label. 2) I've added a veth pair, with veth0 being added to Lago's bridge, and with having a VLAN interface (using the same ID) on top of veth1 (veth1.600) dnsmasq was set to listen on/serve veth1.600 without any success, although the VLAN tag is effectively removed. Similarly, DHCPDISCOVER(s) are being received, without any offers being sent. After setting an address manually on eth0.600, I was able to ping veth1.600 <-> eth0.600. Thanks, Leon
