    problem with running UML!

    I've just used the "HOW TO VDS" tutorial to use UML, but I fail

    when I run the following command, after a bit, a welcome text will appear and after that, my ssh hangs and I just have to start a new ssh session!
    The Command: "/home/vds1/linux ubd0=root_fs root=/dev/ubd0 mem=128m"

    may someone helping me to solve the problem?

    check if the paths is ok
    and the root=/dev/ubd0 not need it .

    Loop mount the file system and chroot into it then run

    mv /usr/lib/tls /usr/lib/tls.broken
    mv /lib/tls /lib/tls.broken

    Umount the image and reboot it

    And the kernel you are running is 2 years old. It'd pay to build a newer one. e.g. the latest blaisorblade bs version. - VPS Hosting and Dedicated Server Hosting since 2003 - Peace of Mind Web Site Monitoring
