I'm having trouble recreating this.  I'm running a Fedora 17 64-bit host 
and a Fedora 17 64-bit guest with domain XML that mirrors yours.

Here's the domain XML I'm using and the resulting QEMU command line:

Domain XML:   http://pastebin.com/DWa4RQ1Y
Command line: http://pastebin.com/2QTWsUhP

I'm running with QEMU commit 8db972cfa469b4e4afd9c65e54e796b83b5ce3a2 
which is 1.2.0 with: (a) just the first patch applied, as well as with 
(b) all of this patch series applied.

Any thoughts on what could be different?
