As this bug is currently marked as Won't fix, I'll provide a quick
workaround to have a working OpenVZ VE using Karmic for the VE and Hardy
for the host. I'm running it for a few VZ here (mostly NX application
servers on gnome) and it seems to work correctly so far.
Once you have created your VE, create a new file in etc/init/openvz.conf
inside the VE (so, /var/lib/vz/private/<VEID>/etc/init/openvz.conf)
containing what follows:
---
# OpenVZ - Fix init sequence to have OpenVZ working with upstart
description "Fix OpenVZ"
start on startup
task
pre-start script
mount -t proc proc /proc
mount -t devpts devpts /dev/pts
mount -t sysfs sys /sys
mount -t tmpfs varrun /var/run
mount -t tmpfs varlock /var/lock
mkdir -p /var/run/network
cat /proc/mounts > /etc/mtab
end script
script
start networking
init 2
end script
---
It seems mountall is having a hard time with the way mount points work
during OpenVZ boot sequence, so that init script will mount all the
required mount points, then create /var/run/network as otherwise ifup
won't work (something similar happened with Jaunty), then generate a
clean mtab and finally start networking and switch to runlevel 2 (as
it's not the default runlevel for some reason).
I perfectly know that the above can be considered as a hack and doesn't make
much use of upstart's capabilities but it will probably make some OpenVZ users
happy.
Please feel free to ask for any additional information on how OpenVZ work so we
can figure out exactly what's wrong and how to have it working out of the box
as it used to for nearly all previous Ubuntu releases.
If we can't fix it before, I'll be at the UDS so we can discuss/demo it
there to see how we can get upstart+mountall to work correctly in
containers for the next LTS. I hope that Lucid will have OpenVZ host
support as well (depends on upstream support) or a working LXC to
replace OpenVZ so having Ubuntu working inside such containers would be
a good thing to have.
