The kernel bug traces aren't really helpful at finding out what's wrong
with libvirtd in userspace.

This suggest libvirtd itself is *not* crashing. Some process that 
libvirtd runs is dieing - not sure which though.

Please kill all libvirtd  instances, and making sure you have compiled
with debugging info turned on (ie, '-g' compile flag), then run

 # valgrind /usr/sbin/libvirtd

And also try

  LIBVIRT_DEBUG=1 /usr/sbin/libvirtd

and send the output for both of these.
