And I tried moving all this from Ubuntu 9.10 box over to F11 box 
w/xenner and there libvirt generates a bad xenner command line.  Here is 
the F11 domain log:

LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/xenner -S -M pc -m

QEMU PC emulator version 0.9.1
/*

xenner v0.46 -- run xen kernels in kvm

usage: xenner [options]
options (qemu compatible):
   -help                    print this text
   -S                       start with vcpus stopped
   -kernel     <kernel>     xenified kernel image
   -initrd     <ramdisk>    ramdisk
   -append     <append>     kernel command line
   -name       <string>     set domain name
   -monitor    pty          monitor on pseudo tty
   -m          <memory>     vm memory in megabytes
   -smp        <cpus>       set number of vcpus
   -hd[abcd]   <file>       disk image
   -cdrom      <file>       cdrom image
   -drive      <config>     qemu style disk setup
   -net        <config>     qemu style network setup
   -serial     <config>     qemu style serial line (aka console) setup
   -vnc        <display>    vnc display (needs qemu-dm from xen-tools)
   -k          <kbd>        vnc clients keyboard map

options (xenner only):
   -domid      <id>         set domain id
   -uuid       <uuid>       set domain uuid
   -network    <mac>,<br>   xenner style network setup
   -debug      <nr>         set debug level
   -logfile    <file>       set logfile
   -bootloader <app>        set bootloader
   -cap-on     <name>       enable kvm features
   -cap-off    <name>       disable kvm features
   -nostderr                send messages to logfile only
   -dumpcore                don't catch fatal signals (sigsegv, sigbus)
   -libvirt-caps            print libvirt capability xml snippet

pick device model:
   -qemu-path  <file>       path to qemu binary
   -qemu-dm                 qemu is xensource qemu-dm
   -qemu-upstream           qemu is upstream+patches
               => http://kraxel.fedorapeople.org/patches/

Some more qemu-ish options are accepted but ignored,
so we don't error out when started by libvirt.

When started without kernel specified xenner tries to
get one using the bootloader (pygrub by default).
