to use all controllers.<br></blockquote><div><br></div></div></div></div><div dir="ltr"><div><div class="gmail_quote"><div>That's good to know. Just tried it out, it works.

The debug info above says lxc is using cgfs and not cgmanager. Exactly<br>
which lxc package version are you using?<br></blockquote><div><br></div></div></div></div><div dir="ltr"><div><div class="gmail_quote"><div>I'm using lxc 1.1.5. Exact version 1.1.5-0ubuntu5~ubuntu14.04.1~ppa1 available from ppa:ubuntu-lxc/stable. Reading through the container start logs I had sent in the previous email I found that it is indeed using cgroupfs driver. Is this the cause of the problem? Should I be running cgfs on trusty to begin with?</div><div><br></div><div>Looking at the <a href="https://github.com/lxc/lxc/blob/lxc-1.1.5/src/lxc/cgroup.c#L48" target="_blank">code of cgroup.c</a>, I saw that in the init it checks for HAVE_CGMANAGER macro but I can't seem to figure out where it is being initialized, I'm guessing it should be somewhere in the <a href="http://configure.ac" target="_blank">configure.ac</a> but not sure. My C skills are really rusty now.</div></div></div></div><div dir="ltr"><div><div class="gmail_quote"><div><br></div><div><span style="white-space:nowrap;color:rgb(51,51,51);font-family:Ubuntu,'Bitstream Vera Sans','DejaVu Sans',Tahoma,sans-serif;font-size:12px;line-height:18px"><br></span></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
