I have an Azure Image, which when I use Azure Powershell to create a VM from, despite me setting the ComputerName in the script, the VM is created without setting the ComputerName to the provided value.
$ImageName = 'MyImage'
$RsgName = 'MyRsg'
$VmName = 'MyNewVM'
$DiagnosticStorageName = 'diagnosticsstore5048'
$cred = Get-Credential -Credential 'TheAdmin'
$Image = Get-AzureRmImage -ImageName $ImageName -ResourceGroupName $RsgName
# Get NIC
$nic = Get-AzureRmNetworkInterface -ResourceGroupName $RsgName
# Configure the new VM
$Vm = New-AzureRmVMConfig -VMName $VmName -VMSize 'Standard_A2_v2'
$Vm = Set-AzureRmVMSourceImage -VM $Vm -Id $Image.Id
$Vm = Set-AzureRmVMOSDisk -VM $Vm -Name $VmName'-disk' -StorageAccountType 'StandardLRS' -DiskSizeInGB '128' -CreateOption FromImage -Caching ReadWrite
$Vm = Add-AzureRmVMNetworkInterface -VM $Vm -Id $nic.Id
$Vm = Set-AzureRmVMBootDiagnostics -VM $Vm -Enable -ResourceGroupName $RsgName -StorageAccountName $DiagnosticStorageName
$Vm = Set-AzureRmVMOperatingSystem -VM $Vm -Windows -ComputerName 'dor' -Credential $Cred -ProvisionVMAgent
New-AzureRmVM -VM $Vm -ResourceGroupName $RsgName -Location 'West Europe' -DisableBginfoExtension
Last time I run the script to create the VM, it left the new VM with a computer name of 'WIN-I80O6J22ENS' The Image was created as per the process here: https://docs.microsoft.com/en-gb/azure/virtual-machines/windows/capture-image-resource?toc=%2Fazure%2Fvirtual-machines%2Fwindows%2Fclassic%2Ftoc.json
UPDATE Alot of people think that I am not Generalizing the image correctly, so I wanted to add here how I am doing it. Inside the VM I run:
Start-Process -FilePath $env:windir\System32\Sysprep\Sysprep.exe -ArgumentList "/generalize /oobe /shutdown /unattend:$env:windir\System32\Sysprep\unattend.xml"
Unattend.xml only has one setting in it which is to step the TimeZone.
Once this is completed and the VM OS has shut down, I run the following to get the VM, stop it, and set it to Generalized:
# Shutdown Source VM & Generalize
$SourceVM = Get-AzureRmVM -ResourceGroupName $SourceRsg -Name $SourceVMName
$Null = Stop-AzureRMVM -ResourceGroupName $SourceRsg -Name $SourceVMName -Force
Write-Host 'Stopped Source VM'
Set-AzureRmVm -ResourceGroupName $SourceRsg -Name $SourceVMName -Generalized
Write-Host 'Set Source VM to Generalized'
I have noticed that when the last command is ran, the output is:
It doesn't actually say if it was successful or not?
