Andrea Bolognani 50d68c1d10 qemu: Don't drop firmware type/features information
Now that we no longer reject configurations that include both
this information and explicit firmware details, as long of
course as everything is internally consistent, and that we've
ensured that we produce maximally compatible XML on migration,
we can stop stripping this information at the end of the
firmware selection process.

There are several advantages to keeping this information around:

  * if the user wants to change the firmware configuration for
    an existing VM, they can simply drop the <loader> and
    <nvram> elements, tweak the firmware autoselection parameters
    and let libvirt pick a firmware that matches on the new
    requirements;

  * management applications can inspect the XML and easily
    figure out firmware-related information without having to
    reverse-engineer them based on some opaque paths.

Overall, this change makes things more transparent and easier to
understand. The improvement is so significant that, in a
follow-up commit, we're going to ensure that this information is
available in even more cases.

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
