The function that returns ENOMEM is actually copy_mm. It returns ENOMEM when dup_mm returns 0. copy_mm receives clone_flags and task_struct * tsk. I think tsk is pointing to the new task (the process being forked). copy_mm assigns some values into *tsk, then: tsk->mm = NULL; tsk->active_mm = NULL; then we check if current process...

Hi, I have buit Xen (32 bit) with PAE and can start multiple Paraguests with 4 gig memory, but cannot launch a single VM with more than 4 gb memory.
