I just tried this exact one last week. (It gets stuck half way through boot)
Could you post me the .config file you used, and command line, and/or any
other info?
I would love to try again. I used a pretty defconfig based config
and my invocation blow: (Note that I use make KBUILD_OUTPUT=.build_um)
#!/bin/bash
#
UMDIR=/home/bharrosh/dev/um
ROOT_FS=$UMDIR/Fedora18-AMD64-root_fs-1
UBD_SWAP=ubd1=$UMDIR/swap_file-1
FS_LOCAL_MOUNT=$UMDIR/target_rootfs-1
LOCALHOST_TUN_IP=192.168.1.117
MEM=384M
# run this to install new um drivers into an image
um_mkkernel()
{
mount -o loop$ROOT_FS_OFFSET $ROOT_FS $FS_LOCAL_MOUNT \
&& make ARCH=um KBUILD_OUTPUT=.build_um
INSTALL_MOD_PATH=$FS_LOCAL_MOUNT modules_install
umount $FS_LOCAL_MOUNT
}
# run this to load a UML system
um_load()
{
./.build_um/vmlinux ubd0=$ROOT_FS $UBD_SWAP
eth0=tuntap,,,$LOCALHOST_TUN_IP mem=$MEM
}
