Hi,
I just setup a Gentoo VPS from the gentoo template supplied on openvz.org - I added a few packages recompiled and was going to try install NX on it. But then I decided to restart it and then I realized it would not come back up 
Here is what I found in vzctl.log

Any ideas what went wrong? Or how to find out what killed it?
Thanks!
