[Vserver] alpha and dietlibc
There is a problem with programs compiled against dietlibc on alpha
segfaulting when SIGHUP is trapped. This affects lockfile in the
util-vserver package. It was suggested on irc that the flags and mask
varibales in the sigaction struct for alpha were around the wrong way.
Swapping sa_flags and sa_mask makes the alpha section the same as the
ia64 and hppa section. This patch also tidies that up. So far no more
segfaults when trapping SIGHUP.

[Vserver] Re: capchroot: chroot(): Permission denied
the debian tools/patches are broken, please switch to 2.0-rc4 and 0.30.207, then try again either with a new guest/volume or by removing any dubious permissions/flags from the guest root dir like this: chmod 755 /path/to/vserver/guest chattr -t -i /path/to/vserver/guest setattr --~barrier /path/to/vserver/guest Thanks a lot. I'll try this and let you know if it doesn't solve the problem. Thanks again ! Marc ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

Re: [Vserver] Suse and Yast inside VServer
Hi, I use SuSE SLES 9 guests, except I cheated. Wow, thats great! Exactly what i need! i've tried that one week ago (with suse 9.2 prof.) ... (1) made 2 partitions (2) installed suse to each partition (making 2 minimal installations) (3) used the one as vserver-host, the other as a template for a vserver (4) deploy-vserver ... skeleton (5) copied the template to there (6) replaced fstab (7) done some thinks i don't remind Yep I think 7) is where the problem is :) Luckily I remember what I did mostly! The main problems are because of the way SuSE init works. ok, started from the beginning - seem's to work now :-)) 1) edit the main init script /vservers/foo/etc/init.d/rc and after the initial comment, add: RUNLEVEL=$1 ok, this was the point i didn't do ... 2) edit the /vservers/foo/etc/init.d/network script and put some exit 0's in it. Otherwise you get a hang on vserver startup/shutdown when the guest tries to flush the interfaces/addresses or something. hm, i had to comment-out and disable some other stuff ... things like hotplug-scan-on-boot and boot-logging to /dev/console (which does not exist inside a vserver) ... but no problem - the errors while vserver-start have pointed me in the right direction ;-) Again, thx very much!

[Vserver] solaris containers/zones
I just saw this article come through the big-admin newsletter. I don't currently have any Solaris computers and I haven't used Solaris 10 (or 9 for that matter), so all I can do is read about it. This seems kind of cool and in-line with what my ideal linux-vserver usage would look like. I just use vservers to logically separate applications so that as they grow they can spin off to their own server w/out hassle. Of course, vserver is great for that because it has so little resource overhead. http://www.sun.com/bigadmin/content/submitted/dollar_container.html The feature that strikes me as so intriguing is the ability to allocate CPU resources to zones. Also, look how they create a zone for tomcat. That strikes me as a very easy to use tool (no editing config files, just use set).
