I recently upgraded "libvirt" on Gentoo to 1.2.2-r1 (latest available). I have not used LXC containers for a few weeks, so I don't recall what version of libvirt I was using when my container last booted successfully.

We'll need you to increase the log level to get more detail in this file.
1. Stop the 'libvirtd' daemon
2. Edit /etc/libvirt/lxc.conf and set log_with_libvirtd=1
3. Run
$ LIBVIRT_LOG_FILTERS=1:lxc LIBVIRT_LOG_OUTPUTS=1:stderr /usr/sbin/libvirtd
4. rm -f /var/log/libvirt/lxc/dwj-hfax-dev.log
5. Try to start your guest with virsh
Now send us the much more verbose logfile that was created
Dennis has already knew what's wrong with his environment, his kernel doesn't support securityfs. libvirt should handle this problem.
Its 6807238d that made securityfs required on the host kernel when userns isn't used. -- Doug Goldstein
