Currently there are dedicated wrappers to construct mdevctl command.
These are mostly fine except for the one that translates both "start"

This is not a 1:1 mapping to mdevctl commands because mdevctl doesn't
support a separate 'create' command. mdevctl uses 'start' for both
starting a pre-defined device as well as for creating and starting a new
transient device. The libvirt code will be more readable if we treat
these as separate commands. When we need to actually execute mdevctl,
the 'create' command will be translated into the appropriate 'mdevctl

"start" in libvirt means - "take this object and create an
instance out of it"
"create" in libvirt most of the time means - "take and XML description,
make an object out of it and use it to create an instance"
This gets confusing with mdevctl which uses "start" for both. So, this
patch proposes to use virMdevctlStart in cases where from libvirt's POV
we're starting a defined device (unlike mdevctl). Similarly, use
virMdevctlCreate in scenarios where XML description is passed to
libvirt and a transient device is supposed to be created.

Unfortunately, we can't drop every such declaration - we have to

virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

When generating TC rules for domain's outbound traffic, Libvirt
will use the 'average' as the default for 'burst' - it's been
this way since the feature introduction in v0.9.4-rc1~22. The
reason is that 'average' considers 'burst' for policing. However,
when parsing its command line TC uses an unsigned int (with
overflow detection) to store the 'burst' size. This means, that
the upper limit for the value is UINT_MAX, well UINT_MAX / 1024
because we are putting the value in KiB onto the command line.

The <teaming> element in <interface> allows pairing two interfaces
together as a simple "failover bond" network device in a guest. One of
the devices is the "transient" interface - it will be preferred for
all network traffic when it is present, but may be removed when
necessary, in particular during migration, when traffic will instead
go through the other interface of the pair - the "persistent"
interface. As it happens, in the QEMU implementation of this teaming
pair (called "virtio failover" in QEMU) the transient interface is
always a host network device assigned to the guest using VFIO (aka
"hostdev"); the persistent interface is always an emulated virtio NIC.
When support was initially added for <teaming>, it was written to
require that the transient/hostdev device be defined using <interface
type='hostdev'>; this was done because the virtio failover
implementation in QEMU and the virtio guest driver demands that the
two interfaces in the pair have matching MAC addresses, and the only
way libvirt can guarantee the MAC address of a hostdev network device
is to use <interface type='hostdev'>, whose main purpose is to
configure the device's MAC address before handing the device to
QEMU. (note that <interface type='hostdev'> in turn requires that the
network device be an SRIOV VF (Virtual Function), as that is the only
type of network device whose MAC address we can set in a way that will
survive the device's driver init in the guest).
It has recently come up that some users are unable to use <teaming>
because they are running in a container environment where libvirt
doesn't have the necessary privileges or resources to set the VF's MAC
address (because setting the VF MAC is done via the same device's PF
(Physical Function), and the PF is not exposed to libvirt's container).
At the same time, these users *are* able to set the VF's MAC address
themselves in advance of staring up libvirt in the container. So they
could theoretically use the <teaming> feature if libvirt just skipped
the "setting the MAC address" part.
Fortunately, that is *exactly* the difference between <interface
type='hostdev'> (which must be a "hostdev VF") and <hostdev> (a "plain
hostdev" - it could be *any* PCI device; libvirt doesn't know what type
of PCI device it is, and doesn't care).
But what is still needed is for libvirt to provide a small bit of
information on the QEMU commandline argument for the hostdev, telling
QEMU that this device will be part of a team ("failover pair"), and
the id of the other device in the pair.
To make both of those goals simultaneously possible, this patch adds
support for the <teaming> element to plain <hostdev> - libvirt doesn't
try to set any MAC addresses, and QEMU gets the extra commandline
argument it needs)
(actually, this patch adds only the parsing/formatting of the
<teaming> element in <hostdev>. The next patch will actually wire that
into the qemu driver.)

In commit 88957116c9 I've adapted
libvirt to QEMU's deprecation of -mem-path and -mem-prealloc and
switched to memory-backend-* even for system memory. My claim was
that that's what QEMU does under the hood anyway. And indeed it
was: see QEMU commit 900c0ba373aada4c13d47d95330aa72ec4067ba5 and
look at function create_default_memdev().
However, then commit d96c4d5f193e0e45beec80a6277728b32875bddb was
merged into QEMU. While it was fixing a bug, it also changed the
create_default_memdev() function in which it started turning off
use of canonical path (by setting
"x-use-canonical-path-for-ramblock-id" attribute to false). This
wasn't documented until QEMU commit
8db0b20415c129cf5e577a593a4a0372d90b7cc9. The path affects
migration - the same path has to be used on the source and on the
destination. Therefore, if there is old guest started with '-m X'
it has "pc.ram" block which doesn't use canonical path and thus
when migrating to newer QEMU which uses memory-backend-* we have
to turn off the canonical path explicitly. Otherwise,
"/objects/pc.ram" path would be expected by QEMU which doesn't
match the source.
Ideally, we would need to set it only for some machine types
(4.0 and older) because newer machine types already do what we
are doing. However, we treat machine types as opaque strings and
therefore we don't want to parse nor inspect their versions. But
then again, newer machine types already do what we are doing in
this commit, so when old machine types are deprecated and removed
we can remove our hack and forget it ever happened.

path attributes (such as /dev/nmdm0A and /dev/nmdm0B respectively).
However, making user find a non-occupied device name might be not
convenient, especially for the remote connections.
Update the logic to make these attributes optional. In case if not
specified, use /dev/nmdm$UUID[AB], where $UUID is a domain's UUID.
With this schema it's unlikely nmdm device will clash with other domains
or even other non-bhyve nmdm devices.

We should not mock stat64() when building on Apple Silicon,
because the declaration is not present in the header file.
Detect this situation and handle it gracefully.

On macOS, most of the symbols and declarations that we look at
to determine which versions of stat() we need to mock are not
present; on the other hand, there are some specific wrinkles
that are introduced with Apple Silicon which we will need to
take care of.
To avoid making the logic even more of an opaque mess than it
currently is, move the macOS part to a separate branch.
This commit is better viewed with 'git show -w'.

Found by clang-tidy's "bugprone-not-null-terminated-result" check.
clang-tidy's finding is a false positive in this case, as the
memset call guarantees null termination. The assignment can be
simplified though, and this happens to silence the warning.

This was found by clang-tidy's
"clang-analyzer-security.insecureAPI.bzero" check.
bzero is marked as deprecated ("LEGACY") in POSIX.1-2001 and
removed in POSIX.1-2008.
Besides its deprecation, bzero can be unsafe to use under certain
circumstances, e.g. when used to zero-out memory containing secrects.
These calls can be optimized away by the compiler, if it concludes no
further access happens to the memory, thus leaving the secrets still
in memory. Hence its classification as "insecureAPI".
