How to Create Virtual Machine in Hyper-V Server using Powershell Commands

by Satheesh Kumar on February 6, 2014

If you are thrown into a situation where someone already installed a Windows Hyper-V server for virtualization, it is helpful to understand how to perform certain basic sysadmin operations like creating a new VM.

Once you’ve installed the Hyper-V server free stand-alone version, you can create a new VM using one of the following methods:

  1. Using powershell commands on Hyper-v server.
  2. From Hyper-V Manager (Hyper-v role enabled Windows servers )

Since we love command line, in this tutorial, we’ll discus how to create a new VM using powershell commands on Hyper-V server

1. Lanuch Powershell Command Prompt

Type powershell from the Windows DOS prompt, which will take you to the powershell command line environment as shown below.

Launch PowerShell

2. Use New-VM Command to create VM

The following is the syntax to create a new VM on powershell using New-VM command.

New-VM -Name -Path -MemorystartupBytes

Create a new VM as shown below:

New-VM -Name Testmachine -path C:\vm-machine --MemoryStartupBytes 512MB
  • New-VM = New Virtual Machine (Command)
  • Name = Virtual Machine(Testmachine -is out virtual machine name),
  • Path = Folder Path to store Virtual Machine files,(C:\VM-machine is out VM file location path)
  • MemorystartupBytes = RAM Size to the Virtual Machine,(512MB is out VM machine RAM size)

Powershell Create New VM

Note: After creating the Virtual machine, it will create folder with virtual machine Name and stores all machine files in that folder.

3. Use New-VHD Command to create Hard Disk for VM

The following is the syntax to create a new hard disk for our virtual machine using New-VHD command.

New-VHD -Path c:\vm-Machine\Testmahcine\Testmachine.vhdx -SizeBytes 10GB -Dynamic
  • New-VHD = New Virtual Hard disk
  • Path = folder path to store Virtual hard disk, (As a best practice create the Virtual hard disk inside the Virtual machine folder)
  • SizeBytes = Hard disk memory size
  • Dynamic = It will increase the hard disk size from the size 0Bytes to maximum size (In our case 10GB is the Maximum size )

Powershell New-VHD

4. Attach Virtual Hard Disk to Virtual Machine

The following is the syntax to attach the above virtual hard disk to the new virtual machine using Add-VMHardDiskDrive command.

Add-VMHardDiskDrive -VMName -Path

Attach virtual hard disk to VM as shown below:

Add-VMHardDiskDrive -VMName TestMachine -path "C:\vm-machine\Testmachine\Testmachine.vhdx"
  • Add-VMHardDiskDrive = Adding Hard disk to virtual Machine
  • VMName = Virtual machine name
  • Path = Virtual Hard disk file path

Powershell Add vmharddiskdrive

5. Map ISO Image to Virtual Machine CD/DVD ROM

Enter the following command in powershell to Map ISO image to the Virtual Machine CD/DVD ROM:

Set-VMDvdDrive -VMName -ControllerNumber 1 -Path
  • Set-VMDvdDrive = Set the VM DVD drive settings
  • VMName = Virtual Machine Name
  • ControllerNumber = Drive controller IDS
  • By default Hard disk will in Controller 0 and DVD will be in Controller 1

Powershell Set Vmdvddrive

6. Start the new VM

Start the newly created virtual machine using Start-VM command as shown below.

Start-VM -Name

If you want to install the OS from the Powershell means the Mapping ISO should have auto installation file also. As a best practice, install the OS from the Hyper-V Manager.

If you have to stop the virtual machine, use the Stop-VM command as shown below.

Stop-VM -Name

7. Check New Virtual Machine Status

Use the Get-VM command to check the status of the new virtual machine. As this indicates this new VM is operating normally without any issues.

Get-VM

Powershell Get-vm
