Thanks for taking the time to report this bug. Certainly as root you should be able to attach devices to lxcbr0.
Could you please 1. show the result of 'ifconfig -a' and 'brctl show' 2. do 'sudo lxc-start -n Ubuntu-12.04.5-i386 -f -l trace -o lxc.debug' and attach lxc.debug here 3. try: sudo lxc-create -t download -n p1 -- -d ubuntu -r trusty -a i386 sudo lxc-start -n p1 and let us know whether that succeeds. ** Changed in: lxc (Ubuntu) Importance: Undecided => High -- 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/1406925 Title: lxc-start fails due to insufficient permission for creating netdev Status in lxc package in Ubuntu: New Bug description: After installing an lxc with `sudo lxc-create -n Ubuntu-12.04.5-i386 -t /usr/share/lxc/templates/lxc-ubuntu -- --release precise --mirror http://richtercloud.de:3142/de.archive.ubuntu.com/ubuntu --arch i386`, starting the container with `sudo lxc-start -n Ubuntu-12.04.5-i386 --foreground` fails due to the following error: lxc-start: conf.c: instanciate_veth: 2817 failed to attach 'vethY1J1I1' to the bridge 'lxcbr0' : Operation not permitted lxc-start: conf.c: lxc_create_network: 3100 failed to create netdev lxc-start: start.c: lxc_spawn: 829 failed to create the network lxc-start: start.c: __lxc_start: 1087 failed to spawn 'Ubuntu-12.04.5-i386' lxc-start: lxc_start.c: main: 337 The container failed to start. lxc-start: lxc_start.c: main: 341 Additional information can be obtained by setting the --logfile and --logpriority options. It should be possible to start the container right away after installation of the apt package and handle eventually necessary setup tasks (of permissions, etc.) in `debconf`. Currently it's necessary to comment out all `lxc.network.*` entries in the container configuration file.
