Configuring pvscsi module for centos

If you want to get some serious performance out of a virtual machine, using the paravirtualized disk controller in VMWare ESX server is the way to go.

configure pvscsi as initrd module

For me what it really came down to was this.

1) getting the VM running using a simple IDE controller.
2)Adding a second disk SCSI/Paravirtual controller.
3)Installing VMWare tools
4)I then used a liveCD to copy the first disk
5)Disable the original IDE disk.
6)Profit!
