Hi Team, I installed a fresh debian etch and doing following steps to setup user mode linux : (installed uml kernel and uml utilities from debian etch DVD.) 1) dd if=/dev/zero of=root_fs bs=1M count=4096 2) mkfs.reiserfs -f root_fs 3) mkdir mounted_root_fs 4) mount root_fs mounted_root_fs -o loop 5) rsync -ax --exclude=root_fs / mounted_root_fs 6) vi mounted_root_fs/etc/HOSTNAME Changed the hostname. 7) vi mounted_root_fs/etc/fstab /* After my change line will be like below : */ /dev/ubd/0 / reiserfs defaults 1 1 8) linux mem=128M While starting uml(i.e. linux mem=128M) I am getting the error like : Warning: unable to open initial console. I am using GNOME and doing this from gnome-terminal. Can anyone tell me what are the exact steps I need to do to initialize console? Thanks, Bhavesh. |

So, you're trying to start UML only doing 'linux mem=128M', isn't it? Maybe the command line should be more complex then yours.

Mounting the root filesystem to a loop dir is not necessary to start uml. You may find further information at www.vdd-project.org under the User Mode Linux Section. Best Regards, Flavio |

I tried "linux mem=128M devfs=mount" also, but that is also giving same error. Thanks, Bhavesh. |

Only thing was missing was /dev/console. I created it using mknod(used major and minor similar to my working debian). Now I am able to login in my UML. If you don't specify rootfs then it will find root_fs in the current directory. Thanks, Bhavesh. |
