QA:Testcase CoreOS virtual install

Description

Install Fedora CoreOS as a virtual machine using the next image.

Setup

1. Download and verify the latest FCOS next image for QEMU
2. Familiarize yourself with FCOS provisioning philosophy, i.e. the role of a an Ignition file during system installation.

How to test

1. Create an Ignition file. You can use the simplest example available.
2. Follow Launching with QEMU or libvirt documentation to start up a virtual machine.
3. Log in to your new FCOS system (with the username and password configured in your Ignition file) using the serial console (you're automatically connected to it when you run the installation through qemu-kvm or virt-install).
4. See the IP address printed at the login prompt (alternatively, you can also find it in the ip address command output).
5. SSH into the machine using ssh username@ipaddress (replace username and ipaddress with actual values).

Expected Results

1. The system runs in a virtual machine according to the instructions.
2. You can connect through serial console and SSH.
3. The linked documentation is clear, all steps are understandable, and nothing important is missing from it.
