HyperV VM creation assign virtual switch with powershell

Question

I'm testing with creating vm's and VM settings with powershell to do for some automation.

But i'm not able to acomplish something as simple as setting the correct virtual-switch for the VM :(

new-vm -Name "rr-rds2" -MemoryStartupBytes 45056MB -BootDevice NetworkAdapter -NewVHDPath "D:\hyperv\rr-rds2\Virtual Machines\rr-rds2.vhdx" -Path "D:\hyperv\rr-rds2\Virtual Machines\" -Generation 2 -NewVHDSizeBytes 250GB -SwitchName "VM's - RR"

When i'm removing this switch -SwitchName "VM's - RR" the new virtual machine is created with the network adaptper virtual switch status not connected.

What is the correct way to achieve this when creating the vm after the VM is created?

Answer 1

Hi,

Please try below command:

New-VM -Name rr-rds2 -MemoryStartupBytes 45056MB -BootDevice NetworkAdapter -NewVHDPath D:\hyperv\rr-rds2\Virtual Machines\rr-rds2.vhdx -Path D:\hyperv\rr-rds2\Virtual Machines -NewVHDSizeBytes 250GB -Generation 2 -Switch VM's-RR

I think you need to replace "SwitchName" parameter with "Switch" parameter. Also, please ensure your switch name is correct. There should not be spacing character in the name.

If the problem persists, please take a screenshot of the command running result. Thanks.

Thanks,

Hi,

Could you clarify more about your requirement? What would you like to achieve when creating VM by PowerShell?

If your PowerShell command does not include switch part "- switch <SwitchName>", the VM's networking configuration will be "not connected" by default.

Please kindly check below article for reference.

Answer 3

When i create the machine with the -SwitchName "VM's - RR"

new-vm -Name "rr-rds2" -MemoryStartupBytes 45056MB -BootDevice NetworkAdapter -NewVHDPath "D:\hyperv\rr-rds2\Virtual Machines\rr-rds2.vhdx" -Path "D:\hyperv\rr-rds2\Virtual Machines\" -Generation 2 -NewVHDSizeBytes 250GB -SwitchName "VM's - RR"

new-vm : Invalid query

• FullyQualifiedErrorId : Unspecified,Microsoft.HyperV.PowerShell.Commands.NewVM

When i remove the -SwitchName "VM's - RR" the VM gets created with the network adaptper virtual switch status not connected. So this parameter is not correct. But i dont know why and how to correct this.

Answer 4

That's it. The parameter and the spaces aren't working. What is right command if i want to change it after the VM is created?

Answer 5

Hi,

Do you mean you would like to connect the created VM to a switch by PowerShell Command?

If so, the command can be as below:

Get-VMNetworkAdapter -VMName rr-rds | Connect-VMNetworkAdapter -SwitchName VM's-RR
