Just wondering if there was a howto or other URL that 

explains what is needed to achieve "near native" performance 

on a domU -- for this purpose, I am thinking about a single 

domU running on a physical server, in comparison to that 

same physical server running a vanilla kernel (non-Xenified).

For instance, using a physical partition for VBD v. using a 

file-backed one is one of the more obvious ones. Assigning 

all the VCPUs. And as much RAM as you can get away with 

(maybe leaving the dom0 with 512MB).

But are there others? Since I'm doing PV, I assume I don't 

need to turn on VT in the BIOS? What about 32-bit v. 64-bit 

OS, for the dom0 and for the domU? (I'll be using CentOS-5.) 

Anything else?

johnny
