I forgot to mention in the original post that one process is nothing

the java is nothing but the web component (which we are in the process of
making optional and rewriting the core in C but leaving the web ui in java)
and it does nothing but generate shell scripts which are then run (in the
background)... the shell script it self is nothing more then a stripped
down and reorganized vmrun.sh... namely once the shell script is run (by
the frontend) and the hyperv is started it terminates... for example here
is the ps -agx from our production host:

1707 -- 1994 are me running outside of petitecloud thus the overhead of a
