Azure Generation 2 VMs

Hello. My team builds SLES 15 images from ISO using the virtualbox-iso builder. These get flagged as “Generation 1” versions, but we now need “Generation 2” ones. Is that possible using this builder? I see the hypverv-iso builder has a flag for the generation, but our build servers are linux-based and that builder requires a Windows host architecture (please correct me if I’m wrong).

If this isn’t possible, we’re looking to convert our builds to the azure-arm builder and leverage the (now available) BYOS Marketplace images. However, I wanted to check before we go through that process.

Thanks for any insight!
