When I'm using Context Disk Limits it is necassary to set the context ID in the configuration file with the Option S_CONTEXT.

The following message appears: Starting the virtual server host2 Server host2 is not running Usage: init 0123456SsQqAaBbCcUu When there is no context ID set, the vserver is starting while starting the System. first I have to apologize, yesterday my cat broke my crystal ball, and the spare one is somewhere hidden in the cellar ... so I have to ask: Ohh, that's bad. ;) Here's the info... what kernel version? 2.4.25-v1.27 what patch version? patch-2.4.26-vs1.27.diff patch-2.4.25-vs1.27-q0.14.diff what tools and what tool version? util-vserver-0.30 what host distro?

I've got another Question: Is it correct, that either i can use S_CAPS=CAP_NET_RAW and can ping but also can see the Network Traffic of the other Vserver with tcpdump or don't use S_CAPS=CAP_NET_RAW but can't ping anymore?

[Vserver] test and cowlinks
To avoid sending a pure test message and being banned from the list, I'll have to add something useful as well... cowlinks. Matt and Herbert have told me they really want that project to get finished asap - reason enough for me to give it some more focus again. The patches on the webpage got updated and now include a fix from Herbert. Thanks for that one! If noone beats me to it, I'll check with Andrew Morton whether the three infrastructure patches can be included into -mm. Madcow is called mad because it's just that. You have to decide whether you want hard links or cow links. Either get rid of hard links completely and confuse some programs. Or use them for some directory trees only and get problems whenever moving between madcow-trees and regular trees. Not good. A real cowlink patch is started but still quite ugly. It's a bit embarrasing, but if people don't care and want to test it anyway, feedback is always welcome. I'll try to add some design details to the webpage soon. So if anyone want to participate in any way - coding, testing, discussion, userspace programs, documentation, whatever - please let me know. Help is always appreciated.

Re: [Vserver] HA+Vserver [Was :(no subject)]
Thanks, this is exactly what I am looking for. I will try and translate it to english. I understand all the configuration files, so it is useful. Do you have more then one vserver active on the same host server at a time?

Not good. maybe some information how the COW issue is currently addressed in linux-vserver. we are using something called immutable linkage invert or immutable unlink (or hundred other names folks invented ;) but it basically works like this: you create a hardlink of a file for several servers (sometimes to a template, sometimes just between the servers), then set the immutable attribute (which can not be reverted inside a virtual server), and an additional attribute (now called iunlink) which permits the user to unlink such an otherwise immutable hardlink reference ... this is sufficient for most package updates and similar but of course a smart solution (CoW*) would be appreciated ... btw, the process of identifying identical files and combining them into an immutable but unlinkable hard reference is (here) called unification, and is done by some userspace tools ...
