I am unable to boot a UML guest kernel. Thanks in
advance for any help.
Here is what I did.
Host kernel
patched 2.6.11.10 with skas3-v8.2
Guest kernel
make mrproper
make xconfig ARCH=um
make linux ARCH=um
I got the root fs from
www.stearns.org/uml-root/root_fs.fc-3-base.pristine.20050605.bz2
and after unziping saved it as root_fs.2005060501
I booted the machine with the host kernel, but when i
start the guest with the following cmd line
./vmlinux ubd0=root_fs.2005060501
it kept restarting with the following output:
Checking for /proc/mm...not found
Checking PROT_EXEC mmap in /tmp...OK
