Hi,
the error tells you that the boot module "vmm.lua" could not be found. As it
is not part of your boot FS (see log output) you have to add it to your
modules.list entry.
Please be aware that the vmm lua library cannot be used to start L4Linux.
There you have to use the "traditional" way of using an instance of L4.Loader.
Regards,
Matthias.
