This is odd. On advice from Flockport community I attempted to manually configure the bridge (its basic elements, at least) by entering sudo brctl addbr lxcbr0 sudo ifconfig lxcbr0 10.0.3.1 netmask 255.255.255.0 up
This went just fine, with `ifconfig` reporting (beyond those interfaces already present in the attached file: lxcbr0 Link encap:Ethernet HWaddr 8e:8c:5c:47:3b:bd inet addr:10.0.3.1 Bcast:10.0.3.255 Mask:255.255.255.0 inet6 addr: fe80::8c8c:5cff:fe47:3bbd/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:35 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:3632 (3.6 KB) Note in particular the `inet addr`, which is the same one `lxc-net.log` claimed couldn't be used. However, recycling `lxc-net` fails, either with: server@srv-Ub1404:~$ sudo restart lxc-net restart: Job failed to restart Or server@srv-Ub1404:~$ sudo stop lxc-net stop: Job failed while stopping server@srv-Ub1404:~$ sudo start lxc-net lxc-net start/running In both cases, the bridge is gone from the output of `ifconfig` as a result. `/var/log/upstart/lxc-net.log` is exactly as it is in the attached version (complaining about `dnsmasq.conf`, which is understandable, but also about 10.0.3.1 already being in use). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1367495 Title: Bridge still not created if bind9 is on Status in lxc package in Ubuntu: Incomplete Bug description: This is probably a dup of bug 1240757, created just so I could upload the data requested in that bug report. On a fresh, probably vanilla, ubuntu 14.04 server, I tried using ubuntu 14.04's default lxc. It created containers fine, but they failed to start, complaining lxc-start: failed to attach 'veth9HNUS9' to the bridge 'lxcbr0' : No such device /var/log/upstart/lxc-net.log says dnsmasq: failed to create listening socket for 10.0.3.1: Address already in use This didn't happen on a desktop 14.04 instance, where bind9 is not installed by default.
