Hi, Running the Tux3 kernel code under UML is easy, fast and safe. Here is a recipe where you can be up and running in about ten minutes from a standing start: # get a kernel tree wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.26.5.tar.bz2 tar -xjf linux-2.6.26.5.tar.bz2 cd linux-2.6.26.5 # get the latest tux3 patch and patch the kernel wget http://tux3.org/patches/tux3-2.6.26.5 patch <tux3-2.6.26.5 -p1 # build uml linux with tux3 make defconfig ARCH=um make linux ARCH=um CONFIG_TUX3=y # get a root filesystem wget http://tux3.org/downloads/tuxroot.tar.bz2 # make a tux3 filesystem in a file dd if=/dev/zero of=testdev bs=1M count=1 tux3 mkfs testdev # boot uml using loop back on the root fs and tux3 test fs tar -xjf tuxroot.tar.bz2 ./linux ubda=tuxroot ubdb=testdev Log in to uml as root and: mount /dev/ubdb /mnt ls -l /mnt To debug tux3/uml under gdb: gdb -args ./linux ubda=tuxroot ubdb=testdev run cont <a bunch of times, don't ask> <log in> You can also run uml using real partitions for root and test: ./linux ubda=/dev/sdaX ubdb=/dev/sdaX The only thing that needs to be special about the root filesystem is, /etc/inittab has to refer to the uml ttys. See umlroot/etc/inittab.
