[libvirt-users] Libvirt exiting and respawning

[Stephen Eilert]

Hi,

I'm trying to use Libvirt with LXC, under Ubuntu 11.04, but I can't get it
to work. It keeps exiting and being restarted by upstart. Log file follows.

It appears that it is complaining, among other things, of QEMU. I am not
running QEMU and would like to disable everything except for LXC, but I am
not sure it would fix my issue. I've set the log level to debug, even, but
didn't see anything out of ordinary. Even resorted to strace, but I don't
know enough about libvirtd to try and understand its behavior.

Anyone got any clue about what's causing it to decide to exit?
