Top cmd showing NICE value 97% -what to tune?

Running 2 VM Guests on an HPUX Integrity Server. One Guest runs great, the other is always at a high NICE value and 0% idle as shown in TOP:
What do you think should be tuned to bring down the NICE and increase IDLE %? Thanks in advance

nohup

NICE(1) 						      General Commands Manual							   NICE(1)

NAME

       nice, nohup - run a command at low priority (sh only)

SYNOPSIS

       nice [ -number ] command [ arguments ]

       nohup command [ arguments ]

DESCRIPTION

       Nice  executes  command	with low scheduling priority.  If the number argument is present, the priority is incremented (higher numbers mean
       lower priorities) by that amount up to a limit of 20.  The default number is 10.

       The super-user may run commands with priority higher than normal by using a negative priority, e.g. `--10'.

       Nohup executes command immune to hangup and terminate signals from the controlling terminal.  The priority  is  incremented  by	5.   Nohup
       should  be invoked from the shell with `&' in order to prevent it from responding to interrupts by or stealing the input from the next per-
       son who logs in on the same terminal.

FILES

       nohup.out standard output and standard error file under nohup

SEE ALSO

       csh(1), setpriority(2), renice(8)

DIAGNOSTICS

       Nice returns the exit status of the subject command.

BUGS

       Nice and nohup are particular to sh(1).	If you use csh(1), then commands executed with ``&'' are automatically immune  to  hangup  signals
       while  in  the  background.   There  is	a builtin command nohup which provides immunity from terminate, but it does not redirect output to
       nohup.out.

       Nice is built into csh(1) with a slightly different syntax than described here.	The form ``nice +10'' nices to positive nice,  and  ``nice
       -10'' can be used by the super-user to give a process more of the processor.
