I've just tried with an upstream 4.5.0-rc4 kernel (which does boot on my
laptop).

Unfortunately, it doesn't work yet.

linux-image linux-image-4.5.0-040500rc4-generic
systemd 229-1ubuntu2
lxc 1.1.5-0ubuntu0.15.10.3

starting a container gives:       lxc-start 1455712091.086 DEBUG    lxc_console

Bug description:
  I'n trying to get (unpriviliged) lxc containers to run on wily.  I
  create a container like this:

  > lxc-create -t download -n u1 -- -d ubuntu -r wily -a amd64

  that works.  However, starting the container fails:

  > lxc-start -n u1                                            
  lxc-start: lxc_start.c: main: 344 The container failed to start.
  lxc-start: lxc_start.c: main: 346 To get more details, run the container in 
foreground mode.
  lxc-start: lxc_start.c: main: 348 Additional information can be obtained by 
setting the --logfile and --logpriority options.

  Setting the log priority to debug shows the following (relevant part
  only):

  So it seems a cgmanager issue.  Syslog shows:
