[SOLVED] Packer, Windows, Cloudbase-Init - OS not "seeing" cloudconfig drive.

[ravioli3]

I am trying to create a template using Packer and Cloudbase-Init but have been running into problems with Cloudbase-Init.

Unless I'm misunderstanding something the primary issue is that the cloudconfig drive isn't appearing in Windows after I clone my template that was created by Packer. To confirm, Windows does not see a CDROM drive with the metadata from cloudconfig. Post clone I've even removed the cloudconfig drive that packer created, recreated it (both gui and cmdline) but its still not there. The Cloudbase logs just show it looking for a drive then eventaully moving on to the http server, then failure.

I have created a Windows Server 2022 VM by hand, installed cloudbase-init, created a cloudconfig drive, started VM and was able to see the cloudconfig drive and eventually the settings were applied (besides the password).I'm not sure why my template made with Packer cannot "see" the cloudconfig drive. Maybe Windows doesn't need to see the drive but since I have successfully used cloudconfig when it does I assume it should.

This appears to be an issues with the machine and cpu type.

I switched it to q35/x86-64-v2-AES and the clouddrive is visible.
