<div dir="ltr">Yeah, but I think there are other problems as well. I'm trying the same restore process with a more complex program and seeing odd behavior: the process gets restored, but it seems to be hung. I have a thread in this program that just prints in a loop every second and it never prints after being restored (again, this works fine if I restore into the same container). </div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Apr 24, 2015 at 6:59 AM, Pavel Emelyanov <span dir="ltr"><<a href="mailto:xemul@parallels.com" target="_blank">xemul@parallels.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 04/24/2015 04:47 PM, Ross Boucher wrote:<br>

</span>So the pipe doesn't get inherited when you restore into different container?<br>
