qemu-kvm nic gone after upgrade to F13
by 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:

What's gone wrong? Config files are below.
