This change introduces a new libvirt sub-element <pci> under
<features> that can be used to configure all pci related features.
Currently the only sub-sub element supported by this sub-element is
'acpi-bridge-hotplug' as shown below:
<features>
<pci>
<acpi-bridge-hotplug state='on|off'/>
</pci>
</features>
The above option is only available for the QEMU driver, for x86 guests
only. It is a global option, affecting all PCI bridge controllers on
the guest.
The 'acpi-bridge-hotplug' option enables or disables ACPI hotplug
support for cold-plugged pci bridges. Examples of bridges include the
PCI-PCI bridge (pci-bridge controller) for pc (i440fx) machinetypes,
or PCIe-PCI bridges and pcie-root-port controllers for q35
machinetypes.
For pc machinetypes in x86, this option has been available in QEMU
since version 2.1. Please see the following changes in qemu repo:
9e047b982452c6 ("piix4: add acpi pci hotplug support")
133a2da488062e ("pc: acpi: generate AML only for PCI0 devices if PCI
bridge hotplug is disabled")
For q35 machinetypes, this was introduced in QEMU 6.1 with the
following changes in qemu repo:
(a) c0e427d6eb5fef ("hw/acpi/ich9: Enable ACPI PCI hot-plug")
(b) 17858a16950860 ("hw/acpi/ich9: Set ACPI PCI hot-plug as default on
Q35")
The reasons for enabling ACPI based hotplug for PCIe (q35) based
machines (as opposed to native hotplug) are outlined in (b). There are
use cases where users would still want to use native
hotplug. Therefore, this config option enables users to choose either
ACPI based hotplug or native hotplug for bridges (for example for pcie
root port controller in q35 machines).
Qemu capability validation checks have also been added along with
related unit tests to exercise the new conf option.

This change introduces libvirt xml support to enable/disable hotplug on the
pci-root controller. It adds a 'target' subelement for the pci-root controller
with a 'hotplug' property. This property can be used to enable or disable
hotplug for the pci-root controller. For example, in order to disable hotplug
on the pci-root controller, one has to use set '<target hotplug='off'>' as
shown below:
<controller type='pci' model='pci-root'>
<target hotplug='off'/>
</controller>
'<target hotplug='on'>' option would enable hotplug for pci-root controller.
This is also the default value. This option is only available for pc machine
types and is applicable for qemu/kvm accelerator only.This feature was
introduced from qemu version 5.2 with the following change in qemu repository:
3d7e78aa7777f ("Introduce a new flag for i440fx to disable PCI hotplug on the root bus")

The virtio-mem is paravirtualized mechanism of adding/removing
memory to/from a VM. A virtio-mem-pci device is split into blocks
of equal size which are then exposed (all or only a requested
portion of them) to the guest kernel to use as regular memory.
Therefore, the device has two important attributes:
1) block-size, which defines the size of a block
2) requested-size, which defines how much memory (in bytes)
is the device requested to expose to the guest.
The 'block-size' is configured on command line and immutable
throughout device's lifetime. The 'requested-size' can be set on
the command line too, but also is adjustable via monitor. In
fact, that is how management software places its requests to
change the memory allocation. If it wants to give more memory to
the guest it changes 'requested-size' to a bigger value, and if it
wants to shrink guest memory it changes the 'requested-size' to a
smaller value. Note, value of zero means that guest should
release all memory offered by the device. Of course, guest has to
cooperate. Therefore, there is a third attribute 'size' which is
read only and reflects how much memory the guest still has. This
can be different to 'requested-size', obviously. Because of name
clash, I've named it 'current' and it is dealt with in future
commits (it is a runtime information anyway).
In the backend, memory for virtio-mem is backed by usual objects:
memory-backend-{ram,file,memfd} and their size puts the cap on
the amount of memory that a virtio-mem device can offer to a
guest. But we are already able to express this info using <size/>
under <target/>.
Therefore, we need only two more elements to cover 'block-size'
and 'requested-size' attributes. This is the XML I've came up
with:
<memory model='virtio-mem'>
<source>
<nodemask>1-3</nodemask>
<pagesize unit='KiB'>2048</pagesize>
</source>
<target>
<size unit='KiB'>2097152</size>
<node>0</node>
<block unit='KiB'>2048</block>
<requested unit='KiB'>1048576</requested>
</target>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</memory>
I hope by now it is obvious that:
1) 'requested-size' must be an integer multiple of
'block-size', and
2) virtio-mem-pci device goes onto PCI bus and thus needs PCI
address.
Then there is a limitation that the minimal 'block-size' is
transparent huge page size (I'll leave this without explanation).

Previously we've ran into problems when 'testQemuInfoSetArgs' failed as
calling the actual test executor could lead to a crash if the data
wasn't prepared but reporting an error doesn't play nicely with our test
output which is handled by 'virTestRun'.
To avoid the issue (and as a side effect improve compilation times of
the test files) split up testQemuInfoSetArgs into two functions.
The first is still called 'testQemuInfoSetArgs' and just blindly
populates arguments into a sub-struct of testQemuInfo. This function no
longer reports errors
A new function 'testQemuInfoInitArgs' which is meant to be called from
the test executor then checks errors and prepares the test data. This
one can fail and the test will be marked as failed appropriately.

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.)

The virtio-pmem is a virtio variant of NVDIMM and just like
NVDIMM virtio-pmem also allows accessing host pages bypassing
guest page cache. The difference is that if a regular file is
used to back guest's NVDIMM (model='nvdimm') the persistence of
guest writes might not be guaranteed while with virtio-pmem it
is.
To express this new model at domain XML level, I've chosen the
following:
<memory model='virtio-pmem' access='shared'>

qemuDomainAlignMemorySizes() has an operation order problem. We are
calculating 'initialmem' without aligning the memory modules first.
Since we're aligning the dimms afterwards this can create inconsistencies
in the end result. x86 has alignment of 1-2MiB and it's not severely
impacted by it, but pSeries works with 256MiB alignment and the difference
is noticeable.
This is the case of the existing 'memory-hotplug-ppc64-nonuma' test.
The test consists of a 2GiB (aligned value) guest with 2 ~520MiB dimms,
both unaligned. 'initialmem' is calculated by taking total_mem and
subtracting the dimms size (via virDomainDefGetMemoryInitial()), which
wil give us 2GiB - 520MiB - 520MiB, ending up with a little more than
an 1GiB of 'initialmem'. Note that this value is now unaligned, and
will be aligned up via VIR_ROUND_UP(), and we'll end up with 'initialmem'
of 1GiB + 256MiB. Given that the dimms are aligned later on, the end
result for QEMU is that the guest will have a 'mem' size of 1310720k,
plus the two 512 MiB dimms, exceeding in 256MiB the desired 2GiB
memory and currentMemory specified in the XML.
Existing guests can't be fixed without breaking ABI, but we have
code already in place to align pSeries NVDIMM modules for new guests.
Let's extend it to align all pSeries mem modules.

existing 'memory-hotplug-ppc64-nonuma', was added to demonstrate the
result for new pSeries guests. For the same unaligned XML mentioned
above, after applying this patch:
- starting QEMU mem size without PARSE_ABI_UPDATE:
-m size=1310720k,slots=16,maxmem=4194304k \ (no changes)
- starting QEMU mem size with PARSE_ABI_UPDATE:
-m size=1048576k,slots=16,maxmem=4194304k \ (size fixed)

A previous patch removed the pSeries NVDIMM align that wasn't
being done properly. This patch reintroduces it in the right
fashion, making it reliant on VIR_DOMAIN_DEF_PARSE_ABI_UPDATE.
This makes it complying with the intended design defined by
commit c7d7ba85a6.
Since the PARSE_ABI_UPDATE is more restrictive than checking for
!migrate && !snapshot, like is being currently done with
qemuDomainAlignMemorySizes(), this means that we'll align the
pSeries NVDIMMs in two places - in post parse time for new
guests, and in qemuDomainAlignMemorySizes() for all guests
that aren't migrating or in a snapshot.
Another difference is that the logic is now in the QEMU driver
instead of domain_conf.c. This was necessary because all
considerations made about the PARSE_ABI_UPDATE flag were done
under QEMU. Given that no other driver supports ppc64 there is no
impact in this change.
A new test was added to exercise what we're doing. It consists
of a a copy of the existing 'memory-hotplug-nvdimm-ppc64' xml2xml
test, called with the PARSE_ABI_UPDATE flag. As intended, we're
not changing QEMU command line or any XML without the flag,
while the pseries NVDIMM memory is being aligned when the
flag is used.

For more details about migration with ivshmem, see

It's a optional attribute in libvirt, and qemu will choose default
role for ivshmem device if the user is not specified.
With device property 'role', the value can be 'master' or 'peer'.
- 'master' (means 'master=on' in qemu), the guest will copy
the shared memory on migration to the destination host.
- 'peer' (means 'master=off' in qemu), the migration is disabled.

This patch introduces a new PCI hostdev address type called

PCI hostdevs to the domain XML in an 'unassigned' state, meaning
that the device exists in the domain, is managed by Libvirt
like any regular PCI hostdev, but the guest does not have
access to it.
This adds extra options for managing PCI device binding
inside Libvirt, for example, making all the managed PCI hostdevs
declared in the domain XML to be detached from the host and bind
to the chosen driver and, at the same time, allowing just a
subset of these devices to be usable by the guest.
Next patch will use this new address type in the QEMU driver to

This function is called by qemuDomainDeviceDefValidateGraphics(),
which in turn is called by qemuDomainDefValidate(), validating the graphics
parameters in domain define time.
This validation move exposed a flaw in the 'default-video-type' tests
for PPC64, AARCH64 and s390 archs. The XML was considering 'spice' as
the default video type, which isn't true for those architectures.
This was flying under the radar until now because the SPICE validation
was being made in 'virsh start' time, while the XML validation done in
qemuxml2xmltest.c considers define time.
All other tests were adapted to consider SPICE validation in this
earlier stage.

Some of our tests try to validate domain XMLs they are working
with (not intentionally, simply because they call top level
domain XML parse function). Anyway, this implies that we build
domain capabilities also - see
virQEMUDriverGetDomainCapabilities(). And since some domain XMLs
are type of 'kvm' the control gets through
virQEMUCapsFillDomainCaps() and virHostCPUGetKVMMaxVCPUs() to
opening /dev/kvm which may be missing on the machine we're
running 'make check'.
Previously, we did not see this issue, because it was masked. If
building domain capabilities failed for whatever reason, we
ignored the failure. Only v5.9.0-207-gc69e6edea3 uncovered the
problem (it changed reval from 0 to -1 if
virQEMUDriverGetDomainCapabilities() fails). Since the referenced
commit is correct, we need to mock access to /dev/kvm in our
tests.

Although <interface type='ethernet'> has always been able to use an
existing tap device, this is just a coincidence due to the fact that
the same ioctl is used to create a new tap device or get a handle to
an existing device.
Even then, once we have the handle to the device, we still insist on
doing extra setup to it (setting the MAC address and IFF_UP). That
*might* be okay if libvirtd is running as a privileged process, but if
libvirtd is running as an unprivileged user, those attempted
modifications to the tap device will fail (yes, even if the tap is set
to be owned by the user running libvirtd). We could avoid this if we
knew that the device already existed, but as stated above, an existing
device and new device are both accessed in the same manner, and
anyway, we need to preserve existing behavior for those who are
already using pre-existing devices with privileged libvirtd (and
allowing/expecting libvirt to configure the pre-existing device).
In order to cleanly support the idea of using a pre-existing and
pre-configured tap device, this patch introduces a new optional
attribute "managed" for the interface <target> element. This
attribute is only valid for <interface type='ethernet'> (since all
other interface types have mandatory config that doesn't apply in the
case where we expect the tap device to be setup before we
get it). The syntax would look something like this:
<interface type='ethernet'>
<target dev='mytap0' managed='no'/>
...
</interface>
This patch just adds managed to the grammar and parser for <target>,
but has no functionality behind it.
(NB: when managed='no' (the default when not specified is 'yes'), the
target dev is always a name explicitly provided, so we don't
auto-remove it from the config just because it starts with "vnet"
(VIR_NET_GENERATED_TAP_PREFIX); this makes it possible to use the
same pattern of names that libvirt itself uses when it automatically
creates the tap devices.)
