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

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

A clarification... this command line is ok. But as it happens, windows
datacenter does not have a driver for rtl8139. So somehow, this
driverless adapter in windows is effectively causing an "extra" tap
device to be specified on the qemu command line, wreaking havoc with the
networking on the host.
