[fedora-virt] qemu-kvm nic gone after upgrade to F13

[Dr. Michael J. Chudobiak]

Hi all,

I had an instance of WindowsXP running just fine in F12, with "vanilla" 
settings (standard networking). After upgrading to F13, no NIC is shown 
in XP any more.

I can run my VM manually, with working networking, if I use:
qemu-kvm -hda /var/lib/libvirt/images/MikeWindows.img -net nic -net user

If I try to run this image via virt-manager, the NIC vanishes. Oddly, 
the qemu-kvm process does not show a "-net nic" parameter - just a 
"-device rtl8139" flag:

[root at xena mjc]# ps ax | grep qemu

What's gone wrong? Config files are below.
