4. Virtual Machine Concepts
A virtual machine is a software computer that, like a physical computer, runs an
operating system and applications.
Virtual Machine
• Operating system
• VMware Tools™
• Virtual resources such as:
• CPU and memory
• Network adapters
• Disk controllers
• Parallel and serial ports
Virtual Machine Components

7. Benefits of Using Virtual Machines
Physical Machines
Virtual Machines
Difficult to relocate:
Moves require downtime.
Specific to physical hardware.
Difficult to manage:
Require physical maintenance.
Hardware failures cause downtime.
Hardware has limitations:
Hardware changes limit application support.
One-to-one relationship between application and
server.
Easy to relocate:
• Encapsulated into files.
• Independent of physical hardware.
Easy to manage:
• Isolated from other virtual machines.
• Insulated from hardware changes.
Provide the ability to support legacy applications.
Enable servers to be consolidated.

8. VM Creation – Real time Scenario
Virtual Machine(VM) Build Procedure
Pre-Implementation Steps
VM Name
vCPU(s)
vMem
vDisk - 1
vDisk - 2
vDisk - 3 (Optional)
vNIC
Operating System (OS)
Implementation Procedure
Create a VM as per requirement
Install the Guest OS
Post-Implementation Steps
Power on VM
Install VMware Tools or Open VM Tools for Linux
Change the computure name similar as VM display name
Assign IP Address/ IP Settings
Join the System to Domain (If required)
Change the time zone
Activate the Guest OS License
Disable IE Enhanced Security for Windows Servers
Turn off Firewall (Optional)
Enable RDP/SSH
Test the VM access via RDP/SSH
Install Project Specific Applications
VM Guest OS hardening
Provide the VM details to End user/Customer/Client/Tenant
