I'm using Debian 6 hardware node (HN) with Linux 2.6.32-5-openvz-686 and vzctl 3.0.30.2

Created a container with the OpenVZ precreated template for Debian 7, installed openssh-server, and when stop+start the container, and entering, the only processes I see are:
$ ps -A -o comm,args
init            init
upstart-udev-br upstart-udev-bridge --daemon
udevd           /sbin/udevd --daemon
udevd           /sbin/udevd --daemon
udevd           /sbin/udevd --daemon
upstart-socket- upstart-socket-bridge --daemon
vzctl           vzctl: pts/0     
bash            -bash
ps              ps -A -o comm,args


I need to manually set runlevel 5 to start the rest of services:
$ telinit 5
$ ps -A -o comm,args
COMMAND         COMMAND
init            init
upstart-udev-br upstart-udev-bridge --daemon
udevd           /sbin/udevd --daemon
udevd           /sbin/udevd --daemon
udevd           /sbin/udevd --daemon
upstart-socket- upstart-socket-bridge --daemon
vzctl           vzctl: pts/0     
bash            -bash
rc              /bin/sh /etc/init.d/rc 5
rsyslogd        /usr/sbin/rsyslogd -c5
saslauthd       /usr/sbin/saslauthd -a pam -c -m /var/run/saslauthd -n 2
saslauthd       /usr/sbin/saslauthd -a pam -c -m /var/run/saslauthd -n 2
S16sendmail     /bin/sh /etc/rc5.d/S16sendmail start
make            /usr/bin/make all -s -C /etc/mail
sh              /bin/sh -c if [ -x /usr/share/sendmail/update_tls ]; then \ ./usr/share/sendmail/update_tls || true; \ .fi;
update_tls      /bin/sh -e /usr/share/sendmail/update_tls
openssl         openssl dsaparam 2048 -out /etc/mail/tls/sendmail-common.prm
ps              ps -A -o comm,args


I'm going to patch "vz" service in HN to run "telinit 5" on each Debian7 container, but... Does somebody know a cleaner way to solve this?
Is vzctl launching upstart but something is broken in the template to follow the "boot" sequence?

Not sure where you should start debug problem.
just tested with kernel 2.6.32-042stab081.3 and vzctl 4.5.1
works for me. didn't needed to install openssh-server though. it was already included and started.

as a starting point I suggest update to latest rhel6 based kernel and latest vz tools and friends versions.

Tried under CentOS 6.4, and a Debian 7 container boots completely (some process waits several minutes for upstart runs).

Also tried to install vzctl 4.5.1 from "unstable" repository in Debian, but then vzctl doesn't work (some error about a file .so not found).

Instead of installing foreign packages (probably not designed for Debian), I prefer to implement my own patch, which gives a faster result:

1. Install vzctl from "testing" repository (well integrated and works better)

2. Add a line at the end of start() function, in the script file /etc/init.d/vz :
/usr/local/bin/vz-upstarts.sh

3. Create the file /usr/local/bin/vz-upstarts.sh and make it executable (I attach it to this message)


This workaround consists in look each running container for the case hasn't boot the minimal services, and in that case execute "telinit 5" in it.

Try http://download.openvz.org/debian -- it's wheezy-test have all the latest and greatest stuff packed. The command to install the kernel is
apt-get install linux-image-openvz-amd64

As I understand, I can upgrade Hardware Node to Debian 7.1, install kernel and utilities from download.openvz.org/debian and the result is a "stable" Debian Wheezy ready for production (?)

in HN:

$ uname -a

(it seems that the i386 repository in download.openvz.org/debian has similar packages than Debian's distribution repository)
