Re: [libvirt PATCH v4 1/6] conf: Add support for vDPA network devices

This patch adds new schema and adds support for parsing and formatting domain configurations that include vdpa devices. vDPA network devices allow high-performance networking in a virtual machine by providing a wire-speed data path. These devices require a vendor-specific host driver but the data path follows the virtio specification. When a device on the host is bound to an appropriate vendor-specific driver, it will create a chardev on the host at e.g. /dev/vhost-vdpa-0. That chardev path can then be used to define a new interface with type='vdpa'. Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com&gt; ---
