[fedora-arm] arm-image-installer with a qemu disk image

[Sam Varshavchik]

I'm trying to install an aarch64 guest VM on F32 x86-64 host.

I created a suitably large disk image, then proceeded to:

arm-image-installer \
   --image=/home/mrsam/Downloads/Fedora-Workstation-32-1.6.aarch64.raw.xz \
   --target=rpi3 \
   --media=/var/lib/libvirt/images/Fedora-Workstation-32-1.6.aarch64.raw \
   --selinux=ON --norootpass

This churned for a while, and finished with this:

= Proceed? yes

Error: mount Fedora-Workstation-32-1.6.aarch64.raw2 /tmp/boot failed

I surmize that arm-image-installer expected a real /dev to write to,  
instead of what is effectively a plain fie, so it failed to mount the disk  
image. I suppose that what it needs to do is a loopback mount, instead. Is  
there a way to do this?

I tried to create a VM with the raw image, as is. It booted for a while, but  
left me at a login prompt, demanding the root password, and I could not  
proceed any further.
