nope.
also on opteron the -hugemem kernel has no extra overhead (due to some
hardware features in that cpu).
But.... I am wondering. Is this forum really the best way to escalate
customer support escalations for you? ;)
I'm pretty sure VMWare has a support relationship with Red Hat, and I
also suspect that that is a much better venue to get better and more
detailed answers (also because you can give RH more information in a
confidential way)
