[Lxc-users] Problem with lxc-attach on Linux v3.1.0

[Nikhil Handigol]

Just to be sure that wasn't the case, I tried running the executable
directly from the lxc source directory. I got the same error:

$ cd src/lxc
$ ./lxc-execute -n foo -f /etc/mn/host.conf -- /bin/bash
root at mnhost:/home/nikhilh/lxc/src/lxc#

In another terminal:
$ cd src/lxc
$ ./lxc-attach -n foo -- /bin/bash
lxc-attach: Function not implemented - failed to set namespace 'pid'
lxc-attach: failed to enter the namespace
