When you build a Virtual Machine, you will be faced with many options and may go ahead based on its default settings, but today I want to introduce you with a technique when making VM, so you can get better performance for some services.


As explained in previous posts to you how to build a Virtual Machine, you will encounter an option to select the SCSI Controller during installation, which in most cases you choose the Default option, which is LSI Logical SAS, but an option there is a name called VMware Paravirtual, which we want to use for a VM.

Reminder) The 
SCSI Controller will work with your virtual server to communicate between the HDD input and output traffic and has 4 different models. 
Bus Logical Parallel, LSI Logical Parallel, LSI Logical SAS, and VMware Paravirtual SCSI Controllers will be in the making of VMs. Each of the Controller Builder companies simulates relevant drivers for the virtual environment and is available to VMware. VMware itself has a controller for you to increase the performance of I / O traffic. But this option is not easy to use other options.

When should we use VMware Paravirtual: 
Because of the load you use when using this controller on your Resource, you should not use it at all times and for traffic that has Read and especially Write highs and In the term Disk Intensive, for example, File Servers always carry a lot of traffic on your hard disk, and it's better to use this controller for performance and speed.

How to use VMware Paravirtual: 
When you build a VM, you will not see any disk after selecting it and starting to install the OS, and you need to install the drivers for this controller to load the hard disk through the controller. 

 **** When installing VM, be sure to use the Custom option to change the controller.


Select all items according to your needs and use the VMware Paravirtual option when choosing SCSI Controller.


After making the VM, we need to do two things through the Edit Setting:

  • Select ISO to install the operating system and Assign it to the CD Rom

  • Load the controller drivers through Floppy Drive

To do this, we must first link the image to the VM via Floppy

You can access the VMware drivers by choosing the Browse button. Open vmimage folder.


From the vm image folder, you must select the Floppies folder to access the VMware images you need to load the controller.


In this folder, you can access image files that have the Flp extension and access Windows 2008 (used for 2012), 2003, and XP.


At the end, be sure to choose connect and turn on your VM.

After turning on the VM, go through the installation process until you select the hard disk and format it.


As you can see in the figure above, you do not display any hard disk for formatting and installing the operating system, and we must first load the load driver.


Your controller driver has been loaded.


And you can easily install it

It is imperative to note that using this controller to provide the services as described above will help you and do not use it in any circumstances due to Load on Resource, and only at times when your traffic is R / W has the advantage of it.
