is there a way to create Generation 2 VM using Azure SDK? - azure

Question

Azure supports UEFI through Generation2 VM.
I am able to create a Generation2 VM using Azure web console, but I cannot a way to specify the generation of the VM through Azure SDK.
I have found a link in Microsoft Docs to create a manged disk using PowerCLI
https://learn.microsoft.com/en-us/azure/virtual-machines/windows/generation-2#frequently-asked-questions
I looked into online documentation of Azure ComputeClient#virtual_machines#create_or_update() api. But still cannot find in the python code docs, any way to specify HyperVGenerations to the VM.

Yes. It's kind of counterintuitive but it goes like this: you need to specify the VM generation on the disk; then the VM, created off of this disk would be of that same generation.
If you already have a disk of gen2 then you just pick it up and specify it when creating the VM. However, I had to create the disk from a VHD file. So when you're creating the disk, you gonna need an IWithCreate instance and then chain a call to the WithHyperVGeneration method. Like this (C#):
public async Task<IDisk> MakeDisk(string vhdPath)
{
return await Azure.Disks.Define(name)
.WithRegion(Region.EuropeWest)
.WithExistingResourceGroup("my-resources")
.WithWindowsFromVhd(vhdPath)
.WithStorageAccount("saname")
.WithHyperVGeneration(HyperVGeneration.V2) // <--- This is how you specify the generation
.WithSku(DiskSkuTypes.PremiumLRS)
.CreateAsync();
}
Then create the VM:
var osDisk = await MakeDisk("template.vhd");
var vm = await Azure.VirtualMachines.Define("template-vm")
.WithRegion(Region.EuropWest)
.WithExistingResourceGroup("the-rg")
.WithExistingPrimaryNetworkInterface("some-nic")
.WithSpecializedOSDisk(osDisk, OperatingSystemTypes.Windows) // <-- Pay attention
.WithSize(VirtualMachineSizeTypes.StandardB2s)
.CreateAsync();
