Tried the usual things like deleting several startup file in /etc/init, deleted /sbin/udevd, etc.

This is somewhat frustrating in that every new release of Fedora has the same problem. It would be nice if there were some sort of fix it script to fix the pty problem.

When I run vzlist from the host there's only one process running in the ve.

Same thing here with Fedora 14.
Do not yum update the upstart package.
Only use the Fedora 14 template "as-is" until more information is available.
Good Luck,
Steve H.

I need to use yum. That's how I update.

I also use yum to update inside containers.

A "yum update" inside a FC14 VE will update it including the "upstart" module and then you will have a broken container ;(

Unfortunately "upstart" is considered to be a dependency for a lot of other packages and it is difficult to exclude it from any sort of update or package installation.

I've switched back to using good old, static FC12 for now as the basis for the Asterisk VoIP containers I build and deploy. I will try SL6 to see if this bug is present there.

Cheers,
Steven H.

I wonder if we could get the Fedora folks interested in making Fedora OpenVZ container aware/friendly?

I've spoken with one of their policy makers and I doubt it.
They really like KVM. Even LXC doesn't get the attention it deserves.

I have opened a Fedora 15 bug. Here is a link for anyone who is interested in following it. Maybe one of you can help the process along.

Unless they change it systemd now requires kernel 2.6.35 or greater.

Hm. Perhaps OpenVZ team could add the needed functionality if we find out exactly what is it that is missing from the kernel (if that really is the reason).

Perhaps you could add to the bug report that OpenVZ uses an additionally modified RHEL 6 kernel - that's not a stock 2.6.32. RHEL backports functionality too, not just bugfixes.

Apart from that - since Red Hat invests a lot of effort into KVM, they might not be that much interested in pushing OpenVZ (or lxc) compatibility changes into Fedora. But any community member could do it, as long as it's accepted by them...

This is the feature that wants a 2.6.35 kernel for systemd. I copied it from a comment in the bugzilla I filed.

What's the kernel version? There is a known problem related to capabilities when running on kernel < 2.6.38. If it's that, try commenting out all "CapabilityBoundingSet=" lines in /etc/systemd/system/*
