Perhaps dpkg -S can shed some light? I observe this on one of my Debian boxes (not running upstart): root@kir-deb71-ovz:~# dpkg -S /etc/init sysvinit-utils, ifupdown, udev: /etc/init /etc/init/ isn't a standard path in Debian.

Re: [Users] vzctl start yields err=-12
I'm honestly not exactly sure of the reason. When I ran into the -12 error problem you're experiencing, I was applying the ovz dostoevsky patch to vanilla centos 5.2, salgix 5.0.4 and debian unstable (both with debian's stock 2.6.26 kernel and a vanilla 2.6.26 kernel). I never received the kernel errors in openvz Bug 802 either but tried the change mentioned in the bug report in the kernel build files and it worked for me. The problem seems to exist due to an inability in openvz (at least the dostoevsky, it may be fixed in later releases) to utilise the fair scheduling kernel profile in linux.

Re: [Users] vzctl start id VE start in progress, vzctl statusVEID exist mounted down, vzctl enter VE is not running
Oh I see. There is an open bug about it already in our bugzilla. http://bugzilla.openvz.org/show_bug.cgi?id=436 Still, I want to resolve this by adding -z argument handling to upstart. I have already asked about it (see http://bugzilla.openvz.org/show_bug.cgi?id=436#c6), but got no reply so far. Perhaps you could ask, too. Stephen Fletcher wrote: Issue was due to running Ubuntu 6.10 Edgy as the guest. I tried re-symlinking mountdir/bin/sh to bash instead of dash but this did not help. Perhaps is due to Edgy using upstart daemon instead on regular init.
