Excuse a newbie question, but if I understand correctly your statement,
then the following:

host@:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root       183G   15G  159G   9% /
tmpfs           119M     0  119M   0% /dev/shm

implies that the maximum memory a single UML instance can have is 119MB?
As in:

./linux ubda=root_fs mem=119MB

Thank you for your time,
