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)
