Debdiff which works for me. I tested this by creating a cloud container, temporarily setting USE_LXC_BRIDGE=false, rebooting, building the package, setting USE_LXC_BRIDGE=true (leaving 10.0.3 as the lxcbr0 subnet), rebooting. lxcbr0 comes up with 10.0.4.1 as expected. A nested trusty container works fine.
The package is targeted at wily, should be at xenial presumably. That should be the only needed update. ** Patch added: "lxcnet.debdiff" https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1509414/+attachment/4503325/+files/lxcnet.debdiff -- 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/1509414 Title: lxc postinst script checks available interfaces, can choose Status in lxc package in Ubuntu: Confirmed Bug description: [Problem] The released wily image preinstalls lxc, which breaks the assumption that lxc's preinst packaging script makes: It inspects the network to try to pick a 10.0.N.0 network that isn't being used, with N starting at 3, so this appears to have picked 10.0.3.0 when it was installed on whatever system was generating the image. This conflicts with the network that eth0 gets attached to when the image is brought up in a container, because it gets attached to the host's lxcbr0, which is using 10.0.3.x. This affects LXC, and should affect LXD but doesn't currently. (see #2) The easiest way to reproduce this is to use the ubuntu-cloud lxc template on a wily host: [Test Case] sudo lxc-create -t ubuntu-cloud -n wily sudo lxc-start -n wily sudo lxc-attach -n wily # inside container, test connectivity, eg: apt-get update [Regression Potentional] Currently none as networking didn't work initially.
