</div>From what I can tell, based on some threads from back in March, the<br>
patchset has not been merged into the upstream kernel at this time and<br>
is almost certainly NOT in 2.6.38.*.<br>
<br>
I'm currently running Fedora 15 2.6.38.8-32.fc15.x86_64 which does not<br>
have the patch and lxc-attach gives this error:<br>
<br>
[root@forest Alcove]# lxc-attach --name Alcove<br>
lxc-attach: Does this kernel version support 'attach' ?<br>
lxc-attach: failed to enter the namespace<br>
<br>
That's probably about the best answer you're going to get.<br>
<br>
>From what I can tell, the last patchset is here:<br>
<br>
<a href="http://lxc.sourceforge.net/patches/linux/2.6.38/" target="_blank">http://lxc.sourceforge.net/patches/linux/2.6.38/</a><br>
<br>
If you want it, you're probably going to have to build yourself a custom<br>
kernel with it patched in.<br>
<br>
Some of the patches have been merged into the upstream kernel but it's<br>
not clear to me if we'll have to wait for 3.0 to be released to see them<br>
but I suspect that to be the case. We're currently sitting at 3.0-rc7<br>
on that one. 2.6.39.3 is released and stable nut I have no clue what's<br>
in there. 2.6.38 is currently at 2.6.38.8, which is what we see in F15<br>
so it is what it is.<br>
