Hi,

What does the following error message mean?

Maybe you have and open console and run something inside the container - or you have done 'vzctl exec' or 'vzctl enter'?

You are partly right. I did have an open console but nothing was running inside the console, nor did I have done 'vzctl exec' or 'vzctl enter'. If I close the console it migrate as expected. A bid strange since I don't recall an open console preventing migration of a VM?

That was always the case (standard openvz behavior)
