One (euro) cent :
does the /usr/var/run/vservers/ directory exists ?
If no : create it
If yes : what happens if you try "touch /usr/var/run/vservers/vcrux01" before
vserver .. start ?

Yes the directory exists. If I touch this file and start again the vserver: the file is deleted and Errormessage is the exactly same. Thanks, but that not solve the problem. Any other ideas ?

Yes as Herbert notes from your output: Use dietlibc: no (you have been warned) I think you may have overlooked the following line from the crux install notes: sudo prt-get install dietlibc I believe you need to use dietlibc, I had troubles without it. Herbert suggested I try it. All worked fine after. If you search the ml/irc archives at the very least you'll find my issues. I have included a snippet below.

Network virtualization reduse overhead of using VPS at box. But it need full virtualization, not are only virtualize routing tables how it do at ngnet.

Current OpenVZ kernel has more than 200 patches backported from mainstream. Second is resource management. There are a lot of resources that can be abused from inside VServer guest or OpenVZ VPS, leading to at least DoS; some of those resources are not under control of traditional UNIX means such as ulimit.

What's the sense in having two or more vservers sharing the same context? It may occur with vserver's having a dynamic context id that a context id gets reused, but you should use static context ids anyway. And even if there's another vserver running in the same context, do you really want a second vserver to be started in that context? I doubt it. So IMHO checking if the vserver is running before starting it is fine in the way it is done right now. > > 2) Deleting vservers .ctx file makes no sense >either because it can be missed by a hard reboot, >kill, etc. > And it's not necessary, if no process is actually running in the context whose id is stored in the .ctx file, the vserver is considered "not runnning". > 3) Solution: before starting any vserver test >for ALL vservers if they are running and remove >remaining .ctx files of not running ones. >Once booted into the schema everything should work. >(hopefully *sigh*) Now where's the difference, apart from the fact that all outdated .ctx files are removed? Your patch removes exactly those files that would not lead to the result that a vserver is considered running...
