Apparently at some point in the past, when there were multiple types
to represent PCI addresses, the function
virPCIDeviceAddressGetSysfsFile() used one of those types, while
virDomainHostDevDef used another. It's been quite awhile since we
reduced the number of different representations of PCI address, but
this function was still creating a temporary virPCIDeviceAddress, then
copying the individual elements into this temporary object from the
same type of object in the virDomainHostDevDef.
This patch just eliminates that pointless copy.

When this function was recently changed to add in parsing of
IFLA_VF_STATS, I noticed that the checks for existence of IFLA_VF_MAC
and IFLA_VF_VLAN were looking in the *wrong array*. The array that
contains the results of parsing each IFLA_VFINFO in
tb[IFLA_VFINFO_LIST] is tb_vf, but we were checking for these in tb
(which is the array containing the results of the toplevel parsing of
the netlink message, *not* the results of parsing one of the nested
IFLA_VFINFO's.
This incorrect code has been here since the function was originally
written in 2012. It has only worked all these years due to coincidence
- the items at those indexes in tb are IFLA_ADDRESS and IFLA_BROADCAST
(of the *PF*, not of any of its VFs), and those happen to always be
present in the toplevel netlink message; since we are only looking in
the incorrect place to check for mere existence of the attribute (but
are doing the actual retrieval of the attribute from the correct
place), this bug has no real consequences other than confusing anyone
trying to understand the code.

libvirt can retrieve traffic stats for emulated interfaces that are
backed by tap or macvtap devices, but this information wasn't
available for hostdev interfaces (those that are implemented by
assigning an SR-IOV VF device to a guest using vfio):
#virsh domifstat instance --interface=52:54:00:2d:b2:35
error: Failed to get interface stats instance 52:54:00:2d:b2:35
error: internal error: Interface name not provided
For some SR-IOV VF devices this information is available via the
netlink VFINFO_LIST request/response, and that is what this patch uses
to implement stats retrieval for VF. Not that this is dependent on
support in the PF driver - for example, the Mellanox ConnectX-4 Lx
(mlx5) driver reports usable stats, while Intel 82599 (ixgbe) and
82576 (igb) just report all stats as 0. (this is the same result as
"ip -s link show").

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'.

SCSI hostdev setup requires querying the host os for the actual path of

Host preparation steps which are deliberately skipped when
pretend-creating a commandline are normally executed after VM object
preparation. In the test code we are faking some of the host
preparation steps, but we were doing that prior to the call to
qemuProcessPrepareDomain embedded in qemuProcessCreatePretendCmd.
By splitting up qemuProcessCreatePretendCmd into two functions we can
ensure that the ordering of the prepare steps stays consistent.

virHashTable that has NULL as dataFree callback => the table does
not own the value. This is not that obvious since
hypervSetEmbeddedProperty() accepts a non-const pointer. This
fact makes it unnecessary hard to consume, e.g. if we wanted to
