A domain's <interface> or <hostdev>, as well as a <network>'s <forward>, can now have an optional <driver name='kvm|vfio'/> element. As of this patch, there is no functionality behind this new knob - this patch adds support to the domain and network formatter/parser, and to the RNG and documentation. When the backend is added, legacy KVM PCI device assignment will continue to be used when no driver name is specified (or if <driver name='kvm'/> is specified), but if driver name is 'vfio', the new UEFI Secure Boot compatible VFIO device assignment will be used. Note that the parser doesn't automatically insert the current default value of this setting. This is done on purpose because the two possibilities are functionally equivalent from the guest's point of view, and we want to be able to automatically start using vfio as the default (even for existing domains) at some time in the future. This is similar to what was done with the "vhost" driver option in <interface>.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
