QA:Testcase install repository Mirrorlist default

Description

This is to verify that Anaconda installs successfully from a network repository auto-selected during installation.

Setup

1. Prepare an installation media that uses network installation by default. Usually that is one of:
   • netinst.iso (from CD or USB)
   • PXE boot with inst.stage2 boot option
   • PXE boot with inst.repo boot option and a partial repository (containing Anaconda stage2 image, but not yum package repository)

How to test

1. Boot the media and do not enter the dialog for setting an installation source, leave it at the default settings
2. Finish the installation

Expected Results

1. System boots into the installer properly
2. Installer defaults to auto-selecting a network mirror with no user interaction required
3. Installer uses the mirror to install required packages
