I noticed the other day that guests which are configured in qemu/kvm with -net nic,... (no explicit model), no longer get the default model which was rtl8139. I wasn't sure if there is now no default model at all, or if the default model changed to something else. This may be related anyhow.

That shouldn't be the case; please file a new bug if you can reproduce this. I just tried with latest F-11 and rtl8139 does seem to be used as the default.
