You didn't make any filesystem! You just allocated the space for it. You
have to make filesystem in that image - using mkfs.* (probably
mkfs.ext2) and you have to populate it with files needed for root
filesystem - to do that you have to mount it on the host using the
loopback and install files there (like you were creating a rescue
diskette or distro instalation diskette). Then if you call it root_fs,
uml will add apropriate options by default.

Alternatively you can get an already set up root filesystem from
download page at sourceforge.
