Well, I had to quickly do up a dev CentOS VM for WebObjects yesterday and refined my pvscsi howto procedure from earlier in the week. The good news is its a lot quicker and you don’t have to add a 2nd drive. Just install VMTools and run:

# mkinitrd -f –with=pvscsi /boot/initrd-`uname -r`.img `uname -r`

Shutdown. Change the disk controller to Paravirtual. Restart and you are good to go.
