nodedev: Introduce mdev capability for mediated devices
Start discovering the mediated devices on the host system and format the attributes for the mediated device into the XML. Compared to the parent device which reports generic information about the abstract mediated devices types, a child device only reports the type name it has been instantiated from and the IOMMU group number, since that's device specific compared to the rest of the info that can be gathered about mediated devices at the moment. This patch introduces both the formatting and parsing routines, updates nodedev.rng schema, adding a testcase as well. The resulting mdev child device XML: <device> <name>mdev_4b20d080_1b54_4048_85b3_a6a62d165c01</name> <path>/sys/devices/.../4b20d080-1b54-4048-85b3-a6a62d165c01</path> <parent>pci_0000_06_00_0</parent> <driver> <name>vfio_mdev</name> </driver> <capability type='mdev'> <type id='vendor_supplied_type_id'/> <iommuGroup number='NUM'/> <capability/> <device/> https://bugzilla.redhat.com/show_bug.cgi?id=1452072 Signed-off-by: Erik Skultety <eskultet@redhat.com>
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. Daniel Veillard <veillard@redhat.com>
Description
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.
