Simply edit /etc/init/openvz.conf and remove the two mount lines
for /proc and /sys.
That should give you that:
---
# OpenVZ - Fix init sequence to have OpenVZ working with upstart
description "Fix OpenVZ"
start on startup
task
pre-start script
mount -t devpts devpts /dev/pts
mount -t tmpfs varrun /var/run
mount -t tmpfs varlock /var/lock
mkdir -p /var/run/network
cat /proc/mounts > /etc/mtab
touch /var/run/utmp
chmod 664 /var/run/utmp
chown root.utmp /var/run/utmp
if [ "$(find /etc/network/ -name upstart -type f)" ]; then
chmod -x /etc/network/*/upstart || true
fi
end script
script
start networking
initctl emit filesystem --no-wait
initctl emit local-filesystems --no-wait
initctl emit virtual-filesystems --no-wait
init 2
end script
---
And it works fine on Lucid. Basically mountall is now always
mounting /proc and /sys making my upstart job fail as they are already
mounted.
