A few other "fun" facts that I've discovered:

* The only files that exist under /var/lib/nova/instances/INSTANCE_ID/
  are disk and console.log, and the size of console.log is 0.

* Trying to run "virsh qemu-attach PID" on the qemu-kvm process gives
  the following error:

  error: unsupported configuration: No monitor connection for pid 1914

* /var/log/libvirt/libvirtd.log contains a bunch of errors like this:

  error : virNetSocketReadWire:1194 : End of file while reading data:
Input/output error

  (I suspect that there's one for each attempt to start an instance.)

* Finally, realized that the "nova network-create" command in the
  Installation Guide is a bit borked.  ("--bridge-interface=br100"
  doesn't make any sense.)  I've re-created the network:

  My instance is still not getting a VNIC, however.

Sometimes there's nothing left to do but crash and burn...or die trying.
