You really need to look at /var/log/libvirt/lxc/dwj-hfax-dev.log
I did. I thought that I posted the relevant bits. I'll check/repost.
It just lots of this (one set from each test that I did):

I see the "--veth veth1", which is the same of the NIC that cannot be
found. But that NIC is not listed in my domain config XML.
A suggestion would be to make sure that you have all the necessary
kernel options enabled. You can check with: ebuild
/usr/portage/app-emulation/libvirt/libvirt-1.1.2-r1.ebuild setup clean
No errors.

16 days ago, I updated from kernel 3.8.13 to 3.10.7. I could take a brief
outage and down-grade my kernel if you think that is a worthy test.
I just realized that when I composed my original email/bug report, that I
misquoted the version of libvirt that I am running. I am indeed running
"1.1.2-r1", but posted as "1.2.2-r1".

I just ran an "emerge --sync" and noticed that the ebuild file for
libvirt
changed. Now I get a new result. "Unexpected problems, indeed". I will
update my kernel and report back.

Doug, thank you for your assistance. My issue is resolved:
ostara ~ # virsh -c lxc:/// start dwj-hfax-dev
Domain dwj-hfax-dev started
ostara ~ # zgrep "SECURITYFS" /proc/config.gz
CONFIG_SECURITYFS=y
Suggestion: libvirtd, or its start script, should sanity check the local
kernel and issue a warning if its not kosher.
[off topic]. Timing! My last reboot was 16 days ago. Between reboots my
EXT3 file-system crossed the 180-days without a FSCK mark... My reboot
took a looooooonnnnggg time. My server is in my basement. When it did not
come back up quickly post-reboot, I got nervous and had to go check on it.
:) 2.4 million files makes FSCK slow. Too bad QEMU performs poorly when
ran on top of btrfs, or I would convert. (yeah, I know about disabling the
COW flag per file/directory)
