Study Notes
Purpose of Virtualization
- Virtualization creates a software-based representation of hardware components or entire systems, allowing multiple operating systems to run on a single physical machine.
- Virtual Machines (VMs) are essential for executing applications and can be hosted on physical servers or personal computers.
Sandbox Virtualization
- Sandbox virtualization creates isolated environments for testing, allowing developers to work without affecting production systems.
- It provides a secure space for software development, installation, and upgrades.
Application Virtualization
- Enables virtual installation and access to applications, reducing licensing costs and increasing accessibility for remote employees.
- Simplifies application maintenance and installation processes.
Legacy Software Access
- Virtualization provides access to outdated proprietary software, even if the user's system runs a newer OS.
Cross-Platform Virtualization
- Allows applications designed for one operating system to be used on another, enhancing compatibility.
Hardware Optimization
- Optimizes physical hardware usage by allowing multiple tasks to be processed simultaneously instead of idling.
Host Machine and Hypervisor
- The host machine is a physical server that shares hardware resources like CPU, RAM, and storage with VMs, managed by a hypervisor.
- Hypervisors (Type 1 and Type 2) facilitate interaction between VMs and hardware without passing through the host OS.
Virtual Machines and Virtual Hard Disks
- VMs are software implementations of computers, operating independently with their allocated resources.
- Virtual Hard Disk (VHD) files simulate hard drives for VMs, acting as storage.
Virtual Networking Components
- vSwitches enable communication between VMs by filtering data packets, while vRouters carry out routing tasks within virtual environments.
- Virtual firewall applications (VFAs) monitor and filter network traffic for security purposes.
Hypervisors
- Hyper-V is Microsoft’s hypervisor, with two types:
- Type 1: Bare-metal hypervisors that run directly on hardware.
- Type 2: Hosted hypervisors that operate on an operating system.
- Popular hypervisors include VMware Workstation and Oracle's VirtualBox.
Digital and Product Keys
- Digital licenses activate Windows without requiring a product key, linked to a Microsoft account and hardware.
- Product keys are necessary for activating versions bought from retailers and must be linked to the specific hardware.
Windows Activation Methods
- Key Management Services (KMS): Requires a local KMS server for client activation, with a minimum of 25 or 5 servers.
- Active Directory-based Activation (ADBA): Automatically activates Windows systems on a domain at startup, requiring no minimum threshold.
- Multiple Activation Key (MAK): Activates systems one-time via Microsoft’s hosting and activates without ongoing communication.
Licensing Management Utility (slmgr)
- Utilized for managing Windows activation:
- /ipk: Installs a product key.
- /ato: Activates Windows.
- /dli: Displays summary license information.
- /dlv: Shows detailed license information.
- /xpr: Displays license expiration date.
Customizing the Start Menu and Taskbar
- Adjust Start menu settings through
Settings > Personalization > Startto show or hide recent, most used apps, or folders. - Taskbar options can be configured through
Settings > Personalization > Taskbar, allowing quick access while minimizing clutter.
