I've run GSX on both 4 and 5, nothing really of note to say other than
that VMWare does not yet "support" GSX on RHEL5 as of version 1.0.3.
Really that only means that there aren't pre-compiled versions of the
kernel modules and you will need to re-run vmware-config.pl each time
the kernel is updated

Also, there is a special kernel that helps out on running VMWare that
changes the default speed of the system timer, reducing the LA on the
host system especially if your guests are mostly idle.  The kernel is
available for both 4 and 5.  Please look at
