[virt-tools-list] [PATCH] Add support for setting BIOS path using -boot loader=PATH



From: "Daniel P. Berrange" <berrange redhat com>

Support setting the <loader> XML element to the BIOS path
using -boot loader=PATH. The same loader must be used both
for the initial VM install and post-install configs
