[Qemu-devel] accidental mistyping of command line kills networking

[Beth Kon <eak@us.ibm.com>]

I accidentally entered a command line as follows:

/usr/bin/qemu-kvm -drive 
file=/scratch/images/beth/windows/win2k3_32_R2.dat.10G.img,if=ide -m 
2048 -boot cd -net nic,model=rtl8139 -net tap,script=/etc/qemu-ifup -vnc 
:12 -usbdevice tablet -monitor stdio -net nic,model=e1000 -net 
tap,script=/etc/qemu-ifup

and the machine's networking broke, requiring a network restart to get 
it back in order. The second -net tap,script=/etc/qemu-ifup causes the 
problem.

/var/log/messages shows
 tap0: received packet with  own address as source address

I don't have time at the moment to look into what's going wrong.  Just 
wanted to make people aware.
