Reboot problèmes

Can't umount /var/lib/vz/root/100: Device or resource busy - solution Shutdown then umount (which appears in the same menu)

df -h (to see what's mounted)

runlevel unknown - solution : in virt1, vzctl enter 104, puis telinit 2

For many of us, the solution is already in this Bug report. Namely:

From comment #54

Comment out “console output” in all /etc/init/*.conf files that have it.

From comment #73

Add “started rsyslog” to the “start on” stanza in /etc/init/rc-sysinit.conf:

start on ( filesystem
and started rsyslog
and net-device-up IFACE=lo
)
From comment #79

Add “init='/sbin/init –verbose'” to the linux boot line in grub.

Folks: Have any of you found this insufficient? Was there anything else you had to do to achieve reliable boots?
