Yes, entering for Fedora kernel doesn't work. You can ssh into container instead,<br>
the [1] article describes how to setup networking for container to make it<br>
migrate-able.<br>

<br>
</span>Entering openvz container only works for patched kernel. But for patched kernel<br>
there's still no criu support :( But openvz kernel guys are working on it.<br>

<br>
</span>Well, for openvz-related questions the <a href="mailto:devel@openvz.org">devel@openvz.org</a> is good place to start, but<br>
for C/R and live migration questions it's better to at least Cc: criu@ mailing list.<br>
