Why virtualization is important?
What problems do we have with classic environments?
Data centers are at capacity Servers are under utilized Legacy hardware and systems Application compatibility issues
How Virtualization Will Help?
Server consolidation Service or application isolation Simplified server deployment Increased service and application availability
Multiple operating systems can run on one consistent platform
Licensing
Some software solutions are not supported in virtual environment
Some software solutions require special license in virtual environment
Some software solutions comes with special virtualization use rights
Hyper-V
Hyper-V Role Overview Server Role Hypervisor-based full virtualization
technology Enables you to create a virtualized
server or client computing environment The Virtual Machine (VM) acts like a real
computer with own operating system and applications

Hyper-V in Windows 8 The same computer virtualization technology that was previously available in Windows Server. Supports Wireless network adapters Supports sleep states and hibernation on
laptops How to Enable it ?
On the Control Panel, click Programs, and then click Programs and Features.
Click Turn Windows features on or off. Click Hyper-V, click OK, and then click Close.
Hyper-V Requirements Intel VT or AMD-V Data Execution Prevention required:
Supported only on x64 processors

Hardware assisted virtualization
The modern x64 CPU’s include hardware assisted virtualization (Intel-VT and AMD-V)
G1 technology was introduced in 2005 (Intel-VT) Makes it possible to support
unmodified guests without emulation and instructions translation
Hardware Assisted Virtualization G2 Adds virtualization layer into the
memory management unit
