[Qemu-devel] Different qemu mashines networking- mac adress

[Matthias Taube]

When I try to start several qemu mashines I get problems with the
networking.

Normal I start mashines with
qemu  -boot c -net nic,vlan=0 -net tap,vlan=0,ifname=tap0 image.img

But starting severel mashines, they would get the same ip from the
dns-dhcp server because of the mac adresses.

So I start with
qemu  -boot c -net nic,vlan=0,macaddr=52:54:00:12:34:56 -net
tap,vlan=0,ifname=tap0 image1.img
and
qemu  -boot c -net nic,vlan=0,macaddr=52:54:00:12:34:57 -net
tap,vlan=0,ifname=tap1 image2.img

I am searching for a script with automatic sets a free mac adress and a
free tapX number.
