Hi,

I got lxc sources from the repo git://github.com/lxc/lxc (lxc 0.9.0), 
and installed it in redhat6. The kernel version is 3.10.0.

I've created an opensuse template and then added the lines to config :
 lxc.tty = 4
 lxc.pts = 1024
 lxc.mount  = /home/container/lxc4test/fstab
...
 lxc.id_map = u 0 10000 2000
 lxc.id_map = g 0 10000 2000

lxc-start failed:
  # lxc-start -n foo  -f config
  lxc-start: Operation not permitted - failed to set mode '020644' to '/dev/pts/5'
  lxc-start: failed to setup the console for 'foo'
  lxc-start: failed to setup the container
  lxc-start: invalid sequence number 1. expected 2
  lxc-start: failed to spawn 'foo'

As the discussion in previous mails, I add this to config: 
  lxc.ttydir = lxc

but lxc-start still failed:
  # lxc-start -n foo  -f config
  lxc-start: Operation not permitted - failed to set mode '020644' to '/dev/pts/1'
  lxc-start: failed to setup the console for 'foo'
  lxc-start: failed to setup the container
  lxc-start: invalid sequence number 1. expected 2
  lxc-start: failed to spawn 'foo'
 
After setting lxc.tty = 0, the result was error too:
  lxc-start: Operation not permitted - failed to set mode '020644' to '/dev/pts/1'.

So ashamed that I have no better ways to solve it now. :(

thanks.
