I think you'd find your best performance just by breaking up LAMP, if
thats the intended use of the rig :)
Keeping mysql and Apache (or your web server of choice) on different
dom-u's means all services have easier times finding contiguous blocks
of cache to take to keep more child servers active during peak load
times.
I'd actually create 3 guests, and just leave the scheduling at default
2 of them web servers, using a central SQL server, for a total of 3.
You can also play around with scheduling later to tweak and learn. I try
to keep everything that malloc()'s much more than it needs (like
apache / mysql) on different dom-u's, whenever possible.
Another config would be use 2 guests, one for sql, one for everything
else. 'Elbow room' in cache is the idea, but having a failover for one
(or both) would be ideal.

Hi
I have a server, Dual Opteron 265 (dual core), witch allow me to have
4 *virtual* CPUs. The server is dedicated to serving dynamic web page.
I have 2 configurations in my mind:
1. I install one operating system;
2. I install Xen with 2 virtuals machines, each one with one cpu (dual
core).
I'm not an expert so I'd like to know what is the best setup to get
the maximun of responsivness and speed from this server.
Thank you
Frank
