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

[Nikhil Handigol]

As an additional datapoint, lxc-attach (from lxc-0.7.2) had worked for me
with linux-2.6.35 with the corresponding setns patches (attached).

Now I need to upgrade the kernel (ideally, to 2.6.38 or 3.0) and I've been
unable to get lxc-attach to work with the newer kernel. Is there any other
information that I can provide to help get this issue resolved?

Thanks,
Nikhil
