sata disk_interface is unable to build

[nick123pig]

Overview of the Issue

When building an image, the disk_interface doesn't seem to be able to build with sata (there's an "unsupported bus type" error from underlying qemu).

In #54, support for sata as a disk_interface option was added, but I have been unable to get it to work. I am able to use sata from virt-install or virt-manager.

Reproduction Steps

packer build with the packer buildfile specified in the example

Plugin and Packer version

$ packer version
Packer v1.9.1
$ packer plugins required example.pkr.hcl 
qemu github.com/hashicorp/qemu ">= 1.0.9" ....../packer-plugin-qemu_v1.0.9_x5.0_linux_amd64

Simplified Packer Buildfile

source "qemu" "example" {
  iso_url           = "https://dl-cdn.alpinelinux.org/alpine/v3.18/releases/x86_64/alpine-standard-3.18.2-x86_64.iso" 
  iso_checksum      = "513dfc3c0c516b803095cd829df72cea956757316247584f0f2ddde7e5b0262f" 
  shutdown_command  = "echo 'packer' | sudo -S shutdown -P now"
  disk_size         = "5000M"
  format            = "qcow2"
  accelerator       = "kvm"
  ssh_username      = "root"
  ssh_password      = "root"
  ssh_timeout       = "20m"
  disk_interface    = "sata"
}

build {
  sources = ["source.qemu.example"]
}

Operating system and Environment details

I've tried this on both Fedora 37 and Ubuntu 22.04 with the standard libvirt/qemu/kvm packages installed.

Hi,

Yes, that happens to me too: I've tried this plugin: v1.0.9, along with all the minor releases from QEMU 8.0.x

Hi @nick123pig , did you get anywhere with this? I'm happy to take a look at the code next week or something, but a follow up to this issue might be nice. @mitchellh ?

[nick123pig]

I ended up changing to scsi, as that seems like the more supported disk interface across the entire libvirt landscape.

Hi, I originaly opened the issue back in 2016 regard SATA support: https://github.com/hashicorp/packer/issues/3983

I need the SATA interface today in order to build and boot a Windows 11 image, and I confirm it doesn't work out of the box:

qemu-system-x86_64: -drive file=output-windows/win11.qcow2,if=sata,cache=writeback,discard=ignore,format=qcow2: unsupported bus type 'sata'

Is it possible to play with the qemu_args to make it work in the meantime ?
