I do it with "lxc -x", example:


root at zoo:~# lxc -x fex uname -a
Linux fex.uni-stuttgart.de 2.6.38-16-server #67~lucid1-Ubuntu SMP Fri Sep 7 18:36:10 UTC 2012 x86_64 GNU/Linux

root at zoo:~# lxc -h
usage: lxc option
options: -l  list containers
         -L  list containers with disk usage
         -p  list all container processes

usage: lxc [-v] -C container [gateway/net:interface]
options: -v  verbose mode
         -C  create new container clone
example: lxc -C bunny 129.69.8.254/24:br8

usage: lxc [-v] option container
options: -v  verbose mode
         -b  boot container
         -c  connect container console
         -e  edit container configuration
         -x  execute command in container
         -s  shutdown container
         -p  list container processes
         -l  container process list tree
