If you change your SCSI back to LSI Logic Parallel...will it boot?
According to this URL:
http://vconfessions.wordpress.com/2008/02/14/changing-vmware-scsi-controller/, W2K3 Server VMs run best with the LSI controller. If it does boot, is there an inherent need to use Paravirtual?
What VMware platform are you using?...ESX, ESXi, Server, etc.?
