- Install with emulated LSI SCSI controller
- Install all relevant online updates for your Linux distribution
- Install
VMWare-Tools (uninstall open-vm-tools and kernel modules which come
already with your distribution prior to install the new Tools)
- Make sure to add
pvscsi
in your "INITRD_MODULES"-Line in/etc/sysconfig/kernel - invoke "mkinitrd" as root
- shutdown
- Change SCSI controller type to "paravirtual" (via vSphere client)
- power on the virtual linux machine
and you're done! Disk access speedup is noticeable.
