Enable VT Support in BIOS

  We need to enable virtualization technology in the BIOS of the physical system. If we haven’t enabled the VT BIOS function the following error message will be obtained. To enable the VT option in the system BIOS, 1. Reboot the physical server. 2. Enter to BIOS mode (Mostly delete or F2 key is used […]

How to Setup Number of Cores Per CPU in a VMware ESX Virtual Machine

  I was checking the details of CPU assignments in VMware virtual machine. In my previous post I have mentioned the method to increase the CPU support in the operating system. VMware virtual machines consider one CPU core as a processor. Virtual CPUs (vCPU) in VMware virtual machines appear to the operating system as single […]

How to Increase CPU count for the VMware virtual machines

  To increase the performance of higher end applications we need to increase the hardware platform of the Operating system. This enhances the capability of the system to perform more effectively. The Organization need more computing speed to improve the application performance. There are cases where the maximum utilization makes the operating system in a […]

How to Enable VMI (Paravirtualization) in VMware ESX Virtual Machines

  VMI, or the Virtual Machine Interface, is a clearly defined extensible specification for OS communication with the hypervisor. In theory Paravirtualization (where the guest kernel knows that it’s running on a hypervisor, not “real” hardware) is faster than pure hardware virtualization. In full virtualization, a guest operating system runs unmodified on a hypervisor. However, […]

VMware File Extensions and its Descriptions

  .VMDK  – These are the actual virtual hard disk files of the virtual machine. These files are having bigger file sizes than any other files located in virtual machine folder.                   -  If we have chosen 2GB split of .VMDK files, the number of .VMDK files depends on the size of the virtual disk. […]
