Using -overcommit flag leads to qemu crashing
Running the following leads to a qemu crash on startup:
jwhite@laptop:~/os$ qemu-system-i386 -overcommit cpu-pm=on
qemu-system-i386: -overcommit cpu-pm=on: There is no option group 'overcommit'
Segmentation fault (core dumped)
jwhite@laptop:~/os$
This fixes the issue:
