</span>There should be a file called dump.log which tells you the error.<br>
However, with current trunk LXC there are some known issues. I've<br>
posted patches for those that need to be merged, but once those land<br>
you may have better luck. (There are still many caveats, one is that<br>
containers using lxcfs are not supported.)<br>
