Greetings UMLers;
I am booting a custom 2.6.24.4 UML kernel, running a debian etch guest
created using debootstrap. I am booting using the kernel command
line:
root=/dev/ubda ubd0=./etch.rootfs ubd1=./etch.swapfs mem=128M
eth0=tuntap,,,192.168.23.5
However, the network interface that gets created isn't eth0 - it's
ethN, where N increments every time I boot the guest (I'm now on
eth19). This prevents the normal boot-time network config from
running properly. Now I can bugger about with a custom script that
uses something like ifconfig `ifconfig -a | grep eth | awk '{print
$1}'` ... but it seems there must be a better way, and in any case I
want to use more than one network device on some of my guests.
I'm not sure what's causing this, but I notice this line in dmesg:
[42949373.660000] Choosing a random ethernet address for device eth0
If it's picking a different mac address each boot, does this result in
the kernel thinking it's a different device and hence assigning it a
different name? How do I stop it doing this?
Cheers,
W
