You talked about setting for a Gig Ethernet card, could you explain this a
little more. I have an Intel PRO/1000 Network Connection with Driver -
version 4.4.12-k1. Currently I'm only pushing about 40Mb from it but I would
like to add my other bank of servers which will bring this up to 150Mb. I
know this is far from the 1000Mb limit of the card but it would be nice to
test the setting before adding more traffic.

That seems reasonable for the boss to ask ;-). Read this thread:
http://marc.theaimsgroup.com/?l=linux-virtual-server&m=105120376431576&w=2
There are banks, large web farms, mission-critical applications, etc. that
are using LVS. And remember, you're already using LVS with your Pirahna
package. If you ask me that's your #1 selling point right there. Just tell
him you don't see the point in switching software to non-LVS, other than to
spend money and possibly break things..

Until you start talking about gigabit cards your LVS should just work once
you get it setup. Gigabit needs a little tuning, like NAPI network drivers
and tuning proc settings.

... There's almost too much information in the HOWTO. You will have to go
over it and look through it. Once you do that just talk to your boss and
your confidence will transfer to him through osmosis and he will approve
your project.
Hope that helps,
