So here is a really random problem. I'm not sure if it is a problem
with UML, or a problem that only shows up under UML.
I am running ubuntu (32 bit) edgy eft (6.10) on both the host and the
guest. I am using the latest edgy vanilla kernel on the host, and
2.6.18 off of blaisorblade's site for the guest. I use the following
command line to launch the guest:
[code]
screen -d -m -S $USER su - $USER -c "cd /home/$USER ; /usr/bin/linux
ubda=root_fs ubdb=swap eth0=tuntap,$TAP mem=$MEMORY"
[/code]
The above is from a script, so the appropriate variables are filled in,
of course.
If my /etc/network/interfaces file looks like this:
[code]
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.4
netmask 255.255.255.0
up route add -host 192.168.1.2 dev eth0
up route add default gw 192.168.1.2
[/code]
then when I screen in to the guest and attempt to login, I have a
problem. I type my user name at the prompt and hit return, and I get an
immediate "Login timed out after 60 seconds". It is impossible to type
the password before this message appears.
However, if I comment the last two lines of /etc/network/interfaces out,
and then use the route command manually after bootup, everything is
great. I think that this is an insane bug, and I'm guessing it is
fairly subtle. I have no idea what could be causing it. It must have
something to do with the interaction between the route command and
consoles, somehow, but I have no idea how. Any ideas?
As a workaround, I can babysit every guest after every restart, but that
is kind of lame, and I'd like to get this fixed in a more permanent
manner, since it is obviously exposing some weirdness somewhere in uml
or upstart or consoles or getty or route or some combination of those.
Thanks as always!
Jonas
