Can't use qemuargs with HCL

[adarobin]

I can't seem to figure out how to use qemuargs with the new HCL2 syntax.

If I put

    qemuargs = [
      [ "-m", "2048M" ],
      [ "-global", "virtio-pci.disable-modern=on" ]
    ]

I get the error

rhel-7-kickstart-test adarobin$ packer build rhel-7-kickstart-test.pkr.hcl 
Error: Unsupported argument

  on rhel-7-kickstart-test.pkr.hcl line 17, in source "qemu" "rhel7":
  17:     qemuargs = [

An argument named "qemuargs" is not expected here. Did you mean to define a
block of type "qemuargs"?

If I switch to

    qemuargs {
      [ "-m", "2048M" ],
      [ "-global", "virtio-pci.disable-modern=on" ]
    }

I get

rhel-7-kickstart-test adarobin$ packer build rhel-7-kickstart-test.pkr.hcl 
Error: Argument or block definition required

hi @adarobin thanks for reaching out. Does the build work if you try something like?

qemuargs {
      qemuargs = ["-m", "2048M"]
 }

 qemuargs {
      qemuargs = [ "-global", "virtio-pci.disable-modern=on" ]
}

hi @adarobin thanks again for reaching out. The code generation for this particular attribute is doing something wrong and not generating the expected schema. I've label this as a bug and will try to see about getting a fix into the next release.

Once fixed the expected configuration should like your first example

   qemuargs = [
      [ "-m", "2048M" ],
      [ "-global", "virtio-pci.disable-modern=on" ]
    ]
