I've got a box with a software bridge on it running as a UML host.
Each UML that runs gets it's own tun device added to the bridge. The
UML is then run like this:
# Start the UML
kernel
ubd0=root_fs \
con0=fd:0,fd:1 \
eth0=tuntap,$IF
where $IF is the name of the tun device in the bridge.
When the UML boots up it does a DHCP to get an address.
Now... all this works in terms of the plumbing but *all* the UMLs have
the same eth device HWAddr (mac address) so they all get the same IP.
I want them to have different IPs.
I thought, because they were all using different tun devices that they
would get different IPs (each of the tun devices in the bridge has a
different HWAddr).
Can someone explain how to make the UML side of the tun devices have
unique HWAddrs?
