Package: qemu
Version: 0.9.1-1

When trying to run several qemu machines in a local mcast based
network, the hosts are not able to reliably talk to each other,
because all of them have the same MAC address.  I know I can hardcode
MAC addresses for each client, but it would be more convenient if this
wasn't required, as I could use the same network setting for all hosts
on the same network.  The script I use to test with qemu is available
as qemu-test-network from
<URL: http://svn.debian.org/viewsvn/debian-edu/trunk/src/debian-edu-config/share/debian-edu-config/tools/ >.

Please make qemu pick a MAC address at random, or using some algorithm
that will increase the chances of each host getting an unique one.
Perhaps some algorithm based on PID and time of day could be used?

Happy hacking,

This is something which is really easy to script (making mac addresses
random), but you're asking something which will break lots of guests, --
for example, almost all modern linux systems will create new ethX device
on each boot in this case, since the MAC will be different and the NIC
will be treated as different device.  The same applies to windows guests.

Marking as wontfix.

Thanks,
