I already have logs with that level of debug logging:
ostara ~ # grep "log_with_libvirtd" /etc/libvirt/lxc.conf
log_with_libvirtd = 1


If it would be useful, I can revert my kernel, reboot, and run libvirtd
with the extra env vars set, as listed above.  Just let me know. :)


I still have the logs from before I upgrades to "libvirt-1.1.2-r1" (lxc
worked for me), and after (libvirt failed).  I've had the extra logging
turned on since last spring when you guys helped me then.  There is not
much interesting (to me anyway) in the log file:
