Welcome to the Manage Virtual Hard Disks with Hyper-V Practice Lab. In this module, you will be provided with the instructions and devices needed to develop your hands-on skills.
In this module, you will complete the following exercises:
- Exercise 1 - Configure Virtual Hard Disks
- Exercise 2 - Manage Virtual Machine Checkpoints
After completing this lab, you will be able to:
- Manage virtual hard disks for an existing guest virtual machine in Hyper-V
- Manage virtual machine checkpoints for a guest virtual machine in Hyper-V
The following exam objectives are covered in this lab:
- Understand server virtualization - VHD and VHDX formats, snapshots and saved states
It will take approximately 60 minutes to complete this lab.
Exercise 1 - Configure Virtual Hard Disks
A virtual disk is a type of disk drive that works like a physical hard disk and used by computer virtualization platforms such as Hyper-V and VMware. Virtual machines utilize virtual disks to run an operating system and store data files. Depending on the virtualization software that you use, virtual disks can be identified with extension names like .vmdk, .vhd and .vhdx files.
Windows Server 2016 Hyper-V supports two virtual hard disk formats - VHD and VHDX.
VHDX is scalable because it supports a larger storage capacity and provides protection from data corruption during inevitable power outages. It can handle structural alignments of dynamic and differencing disks on new, large-sector physical disks.
In this exercise, you will perform the tasks required to create and configure virtual machine storage.
Exercise 2 - Manage Virtual Machine Checkpoints
System settings of virtual machines and physical computers can be modified anytime and these changes whether intentional or unintentional are immediately saved on these devices. When working with physical computers system changes can be reversed by uninstalling the update or software. If the changes caused instability or system errors, IT support can perform a roll back by restoring from the most recent backup. However, it is more convenient with virtual machines as changes in the system settings can be reversed with the use of snapshots or checkpoints in Windows Hyper-V platform.
Checkpoints or snapshots provide a fast and easy way to revert the virtual machine to a previous known state. For this reason, virtual machine checkpoints are intended mainly for use in development and test environments. With the increasing popularity of cloud computing and rapid deployment, virtual machines is used in actual computer environments. However, IT support must be cautious when reverting to a checkpoint as this may have unintended consequences on system stability. Having an easy way to revert a virtual machine can be very useful if you need to re-create a specific state or condition so that you can troubleshoot a problem.
