That's pretty good. One more question, If I create 3 vserver processes by this way, and I allow the 3 processes can access only certain files in my machine, for example, only 4 files on my systems. Can I group the 3 processes and 4 files together? say, they can see each other on their vserver domain, but they will not be accessible by other program on my host machine?

Maybe debian isn't the right word or perhaps you need to change one of the other parameters as well. Without you posting the exact command you ran and the exact output, it's difficult to tell. Maybe searching the wiki / archive for 'how to install a Debian guest', might point you in the right direction . This page: http://linux-vserver.org/Building_Guest_Systems has instructions for Ubuntu guests. Given the common lineage between the two I suspect it could be adapted for installing Debian guests.

I haven't tried it but I see no reason why vserver couldn't be run on your ARM system; assuming that it has a Linux kernel running on it already. It may take a bit of work and you may have to be pretty slow and methodical baout getting it running but it should be possible. When I was trying to get vserver running on my UltraSPARC based server, the people here (esp. Bertl) were very helpful and supportive. I suspect by getting it running on ARM you will help improve the software as well as helping anyone else who is working on using vserver on an embedded platform.

Thank you very much! If I am correct then -d controls the distro of the guest that you are building. By default only the common few distros are supported, but I'm told that it's pretty simple to add support for others (check the Wiki / archives I'd guess). Of the top of my head I couldn't tell you which distros other than Debian have an ARM port.
