Eek, no way. I *have* to use VMware to run Linux at work (otherwise
I would have had to put Linux back on my desktop) and I have been
nothing short of utterly impressed with it's performance on FreeBSD.
(On a side-note, if one has to run both Linux & FreeBSD on the
same box, I hold the opinion that it is actually advantageous
to run FreeBSD as the host and Linux as the guest for two
reasons. Firstly, I could swear VMware runs far faster and
more stable on FreeBSD than it does on Linux (from the machines
we have at work anyway). Secondly, there's always likely to be
better support for Linux as a guest OS.)
I haven't run multiple VMware instances though, nor have I used
FreeBSD as a guest OS -- your mileage may vary.
I'm not really suggesting VMware over jail, I just wanted to inform
you that VMware performs bloody fantastically on FreeBSD.
(Yeah, ok, I'll keep going. My Linux VM actually builds our
work system up to ten minutes quicker than running Linux na-
tively on the same machine. Make of that what you will!)
Regards,
Trent.
