Configure Installation Sources

Several options are available to use as sources for installing an Operating System on a virtual machine.  We will three of the most common methods.

1) Use an iso image of a bootable installation cd or dvd.  To prepare the installation, put a copy of the iso file in a location which is accessible by libvirt, such as /var/lib/libvirt/images.  If desired, several iso image files can be downloaded and kept available for future use.

2) Use a network installation from a PXE boot server.  This will require a PXE boot environment to be preconfigured, and it will require a bridged network connection to the virtual host.  PXE boot will not worik on a NAT network connection by default.

3) Use a distribution's repository directly.  This option does require the host server to be connected to the Internet, but it supports either a bridged network or a NAT network.  To prepare for a network installation from a repository.   Here are several valid URLs for various distributions.
