Agreed, this would be a huge improvement.  Would you like to re-title
this bug to turn it into a feature request for that?  An 'issue' on the
github tracker at github.com/lxc/lxc may be more likely to yield fruit.

If you're able to submit your own patch that would be even better.

The limits would be the practical ones, for instance if you are using
a /24 you can only have 254 addresses on the bridge.

Title:
  unprivileged lxc containers fails with custom bridge

Status in lxc package in Ubuntu:
  Confirmed

Bug description:
  Using 15.04 x86_64 with all the updates installed.
  I'd like 2 containers to communicate with each other via bridge interface. For that I've created interface as follows:
  /etc/systemd/network/internalbridge1.netdev:
  [NetDev]
  Name=ibr1
  Kind=bridge

  /etc/lxc/lxc-usernet:
  # USERNAME TYPE BRIDGE COUNT
  x veth ibr1 8

  The 'x' is my username, it's first and only user configured in the
  system so default id map should work fine.

  The container network is configured as follows:
  lxc.network.type = veth
  lxc.network.link = ibr1
  lxc.network.flags = up
  lxc.network.name = internal
  lxc.network.ipv4 = 10.1.8.2/24
  lxc.network.ipv4.gateway = 10.1.8.1

  I've enabled the service and brought the bridge up - showing ok via
  'ip a' and 'brctl show'. Also works fine with priviledged containers.
  However with unpriviledged containers it fails:

  lxc-start -n asterisk -l debug -F --logfile lxc-user.log
