Hi,
I found out that typing "reboot" in a container halts the whole
container, making it unreacheable (the container itself is not running
anymore, checking with vzlist on the physical machine).
Any idea if there is another command that kills all the processes and
restart the container from within a root shell on the container (yes I
know that you can do that with 'vzctl restart CTID' on the HN)?
Best,

favor, without any possibility of correction by competing courts or

Which vzctl and kernel do you use?
In case of vzctl < 3.0.25 reboot is performed by the vpsreboot cron
script which is
called from cron every 5 minutes by default. Check if your cron daemon
is running,
check that you have that job installed, and note that since this job
is run every 5
minutes, your container can be done for as long as 5 minutes.
In case of vzctl >= 3.0.25 (and a decent/recent kernel) reboot is performed by a
daemon called vzeventd. Check that vzevent kernel module is loaded,
that vzeventd
daemon is running and included in autostart.
