Thanks Daniel!<div><br></div><div>The linux-3.0 patches don't seem to be working for me unfortunately. </div><div><br></div><div>I compiled lxc-0.7.5 with the patched linux-3.0. After starting a container "foo" via lxc-execute,I ran the following command:</div>
<div>$ lxc-attach -n foo -- /bin/bash</div><div><br></div><div>When I run lxc-attach, I get the following error:</div><div><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; background-color: rgb(255, 255, 255); ">lxc-attach: Function not implemented - failed to set namespace 'pid'<br>

<br>
</div>I've done a quick try of the patches with linux-3.0.4 with lxc-0.7.5,<br>
slackware64-13.37 and my existing containers and I'm able to turn them<br>
off easily with<br>
<br>
lxc-attach -n mycontainer -- /sbin/halt<br>
<br>
\o/<br>
<br>
I'll test them more, but in the meantime thanks Daniel!<br>
