The Managing Virtual Machine Settings module provides you with the instruction and server hardware to develop your hands on skills in the defined topics. This module includes the following exercises:
- Configure Dynamic Memory and Smart Paging
- Configure Guest Integration Services
- Create Generation 2 Virtual Machines
Exercise 1 - Configure Dynamic Memory and Smart Paging
Dynamic memory is a feature in Hyper-V where a guest virtual machine has the flexibility to increase its allocated memory on-demand thereby enhancing its performance.
Smart Paging is another feature enhancement in Hyper-V. This ensures successful virtual machine restart operations. In some scenarios, a virtual machine may not have enough memory available than required to restart, in this case, Hyper-V will require more memory to restart the virtual machine. Typically, each virtual machine with a specific operating system requires a specific amount of start-up memory. If you allocate less memory in the Minimum RAM field, then the virtual machine will not start. The restart of the virtual machine will fail. In Windows Server 2012, Smart Paging is used by Hyper-V to restart the virtual machine.
The Smart Paging uses the hard disk as additional and temporary memory when more memory is required to restart a virtual machine. However, because the hard disk access is slower than the direct memory access, there is a performance issue with the virtual machines. Hyper-V is now designed to use Smart Paging in the following conditions:
- When you restart the virtual machine
- When there is no physical memory available
- Reclaim of memory from other virtual machines is not possible
Smart Paging will not be used in the following conditions:
- You are starting the virtual machine, but not restarting
- Memory oversubscription is required
- There is a failover over of a virtual machine in Hyper-V clusters
In this exercise, you will perform the tasks required to configure virtual machine memory and smart paging.
Exercise 2 - Configure Guest Integration Services
Hyper-V Integration Services is a set of software installed on a guest virtual machine that streamlines integration between a Hyper-V host and a virtual machine. Features provided by this suite are a seamless movement of pointing devices and use of Hyper-V Action menu (for example, shutdown and time synchronization between guest virtual machines and Hyper-V host). Integration services are pre-installed with newer Windows operating systems.
Exercise 3 - Create Generation 2 Virtual Machine
Generation 2 is the new variant of virtual machines in Windows Server 2012 Hyper-V feature. This new type of virtual machine has support for Unified Extensible Firmware Interface (UEFI) firmware and has reduced support for a majority of legacy devices. Other enhancements included with Generation 2 are PXE boot by using a standard network adapter, boot from a SCSI virtual hard disk, boot from a SCSI virtual DVD, and secure boot.
In this exercise, you will learn how to create Generation 2 virtual machines.
