Aarch64 (ARM64) unavailable due to lack of IDE drivers for the architecture. CDROM driver should be set via scsi or virtio.

example text in this template can be deleted.

Overview of the Issue

When attempting to create a virtual machine using aarch64 as the architecture, the packer script fails:

kvm: -device ide-cd,bus=ide.1,unit=0,drive=drive-ide2,id=ide2: Bus 'ide.1' not found
TASK ERROR: start failed: QEMU exited with code 1

The same build process works under x86_64. These builds are using the UEFI firmware, not BIOS. It appears for aarch64, there needs to be an option to set the bus for the that device in order to accommodate native, non-x86_64 architectures. This is not using aarch64 emulation under x86_64.

Reproduction Steps

Run packer script on an aarch64 machine (not emulated). The current build is meant to run packer to provision a template and use a kickstart script to install and configure a Rocky Linux 9.3 VM/template.

Plugin and Packer version

• Packer v1.10.3
• Proxmox plugin v1.1.7 (packer-plugin-proxmox_v1.1.7_x5.0_darwin_amd64)

To reproduced the error

packer init packer/rocky9-aarch64/packer.pkr.hcl
packer build -var-file variables-aarch64.pkrvars.hcl packer/rocky9-aarch64/packer.pkr.hcl

In the shell console, this is the result:

proxmox-rl9-aarch64.proxmox-iso.rocky9-kickstart: output will be in this color.

In the proxmox console, the build fails, and shows that the CDROM is trying to be mounted on an ide bus:

TASK ERROR: start failed: QEMU exited with code 1
