Creating my first Vagrant box fails. Trying to virtualize a SD card flasher app. Qemu + Manjaro

Vagrant

[Update]

I have the same problem with packer-arch itself.

Hey there!

I’m planning to virtualize manjaro-arm-installer, so it can be run on every platform.
Docker was my initial aim, because I’m virtualizing an application.
But that so far turned out to be very difficult to do, due to the app running all sorts of systemd functions and also it’s a flasher app, so I probably want virtual partitions as well.
That way, if people choose the incorrect device to flash, it’s only a virtual partition that gets destroyed.

I figure that since manjaro-arm-installer is a CLI app,
and Manjaro releases only GUI OSes these days,
I’m better off building from Arch Linux and work my way up to Manjaro from there.

I’m using Elasticdog packer-arch as my template.

I then converted it’s json packerfile to hcl, took out the virtualbox/vmware/parrarel,
because I figure I only want to use QEMU/libvrt as being the most lightweight virtual machine after docker.

So this is where I’m at right now:

[folaht@pjehrsohmehj mai-base]$ packer build manjaro-arm-installer.pkr.hcl
qemu.mai: output will be in this color.

As one can see it produces an error and I have no idea why.
