How to use differencing Disks in HYPER-V

Differencing Disk is good solution to save hard disk space in your HYPER-V Host when you must deploy multiple Virtual Machines in your environment for test purposes. Of course you can use it in your production environment but you must sure that the Parent Hard disk located in Disk with high performance like SSD because the I/O will be high. 

Differencing Disks can reduce the time and storage requirements but if you use lot of child disks can be a performance hit.  So think very carefully where and why must use Difference disks in your environment.

HYPER-V - How to Access Virtual Disk Properties

As IT Pro very often  create new Virtual Machines for Production Enviroment or for Testing. Create new Virtual Hard Disks for Virtual Machines. In Physical Servers Hard Disks are hardware equipment. But in HYPER-V Host the Virtual Hard disks are files with an extension vhd or vhdx.

Sometimes we need to know specific details for Virtual Hard Disk of a Server. How can find these details ? For Physical Hard Disks already we know all the details when we buy the Disk or we know where can find it after add in the Server.

Today i will continue with the Second and Last Part in HYPER-V Failover Clustering. Use these 2 technologies together to make High Available your Virtual Machines and keep downtime out of the game. In Firs Part i have describe how can enable Failover Clustering , use Validation Wizard and add the nodes that will be act as Clusters.

Today i will describe the following

One of the biggest challenge of IT today is to keep production environment healthy without downtimes. In IT world this means Replications, High Availability, Failover Clustering, Load Balancing. Today most of the Servers are Virtual Servers with Hypervisors to keep the Virtual Servers.

Today i will explain how can keep the HYPER-V Hosts without downtimes in any scenario except from Disaster Recovery. The solution is the Failover Clustering . What is Failover Clustering? 

How to Enable HYPER-V Enhanced Session Mode

HYPER-V in Windows Server 2012 has lot changes. One of them is Enhanced Session Mode. All we know that Virtual Machines don't provide any physical console that you can interact with like a physical computer.

From  my experience lot of times i need to copy/paste files from USB Disk in the Virtual Machibe and i must copy-paste in network location like a User folder, connect Remotely in Virtual Machine or from HYPER-V Host Console and open network location to copy/paste the file or folder.

Windows Sysprep Tool for Virtual Machines

Sysprep is a Microsoft tool  prepares an installation of Windows for duplication, auditing, and customer delivery. Most of you are familiar with Sysprep and has use it lot of times. When you are setup a Windows VM you need to install softwares, drivers, maybe some configuration in firewall, enable Remote Desktop , install critical patches and who know's what else base on every IT requirements. All these takes lot of time every time tha you must insall a new VM.

Sometimes maybe need to move one of our Virtual Machine from one HYPER-V host to another hardware and HYPER-V Host. I wll not explain why must be done because everyone has the own reasons to do it. But The most common reasons that need to move your Virtual Machine are to free up space, free up resource of your HYPER-V Host or to change the hardware of your HYPER-V Host

Manage HYPER-V Integration Services

HYPER-V Integration Services are services that allow communication between virtual machine and HYPER-V host. When install a new Virtual Machine then automatic install a package of services which consists the HYPER-V Integration Services and improve the perfomance and manageability of Virtual Machine.
