# The base VM was downloaded using the following commands:
# mkdir /var/lib/libvirt/images/base
# curl -o http://cloud-images.ubuntu.com/releases/focal/release/ubuntu-20.04-server-cloudimg-amd64-disk-kvm.img /var/lib/libvirt/images/base/ubuntu-20.04-server-cloudimg-amd64-disk-kvm.qcow2

This doesn't look right to me. It would attempt to download the path as a second file, no? The pathname should come after the -o flag.

However, why not just use a normal file download resource in the KVM host recipe in the first place? Same amount of characters as this extended comment, but then it's automated and handles existing files.

We won't want to edit the script on the host all the time, so why not simply:

  --ram $2 \

I always set this to 20.04 when creating VMs in virt-manager.

When I set it to 20.04 virt-install would fail (while setting up SSH), I couldn't find a way to figure out what was going on
