Re: [uml-user] UML Network Failure

[Klaus T. <kla...@gm...>]

Hi Jay,

Thanks again. I see what you mean. here is my command line argument for starting UML now:

 ./linux-2.6.24-rc7 ubda=FedoraCore5-x86-root_fs mem=128M eth0=tuntap,,,192.168.0.254

Right now what I have is the followinge rror message:

SIOCSIFFLAGS: Operation not permitted


I get it first while the machine is booting and second when I try to run  "ifconfig eth0 192.168.0.253 up" at the guest shell. In both guest and host, I am root.

I found on the web that this might be related to permissions issue related to /dev/net/run. I changed the permission of this file in the guest machine to 777. Still, it didn't solved my problem.

Any further idea?

Klaus.
