SmartNIC DPUs may not expose some privileged eswitch operations
to the hypervisor hosts. For example, this happens with Bluefield
devices running in the ECPF (default) mode for security reasons. While
VF MAC address programming is possible via an RTM_SETLINK operation,
trying to set a VLAN ID in the same operation will fail with EPERM.
The equivalent ip link commands below provide an illustration:
1. This works:
sudo ip link set enp130s0f0 vf 2 mac de:ad:be:ef:ca:fe
2. Setting (or clearing) a VLAN fails with EPERM:
sudo ip link set enp130s0f0 vf 2 vlan 0
RTNETLINK answers: Operation not permitted
3. This is what Libvirt attempts to do today (when trying to clear a
VF VLAN at the same time as programming a VF MAC).
sudo ip link set enp130s0f0 vf 2 vlan 0 mac de:ad:be:ef:ca:fe
RTNETLINK answers: Operation not permitted
If setting an explicit VLAN ID results in an EPERM, clearing a VLAN
(setting a VLAN ID to 0) can be handled gracefully by ignoring the
EPERM error with the rationale being that if we cannot set this state
in the first place, we cannot clear it either.
In order to keep explicit clearing of VLAN ID working as it used to
be passing a NULL pointer for VLAN ID is used.

that the device goes onto non-default bus (pci.0) starting such
guest fails, because the controller that creates the desired bus
wasn't processed yet. QEMU processes arguments in order.
For instance, if virtio-mem has address with bus='0x01' QEMU

There are a some scenarios in which we want to prealloc guest
memory (e.g. when requested in domain XML, when using hugepages,
etc.). With 'regular' <memory/> models (like 'dimm', 'nvdimm' or
'virtio-pmem') or regular guest memory it is corresponding
memory-backend-* object that ends up with .prealloc attribute
set. And that's desired because neither of those devices can
change its size on the fly. However, with virtio-mem model things
are a bit different. While one can set .prealloc attribute on
corresponding memory-backend-* object it doesn't make much sense,
because virtio-mem can inflate/deflate on the fly, i.e. change
how big of a portion of the memory-backend-* object is exposed to
the guest. For instance, from a say 4GiB module only a half can
be exposed to the guest. Therefore, it doesn't make much sense to
preallocate whole 4GiB and keep them allocated. But we still want
the part exposed to the guest preallocated (when conditions
described at the beginning are met).
Having said that, with new enough QEMU the virtio-mem-pci device
gained new attribute ".prealloc" which instructs the device to
talk to the memory backend object and allocate only the requested
portion of memory.
Now, that our algorithm for setting .prealloc was isolated in a
single function, the function can be called when constructing cmd
line for virtio-mem-pci device.

While it's true that our virCommand subsystem is happy with

the path to dnsmasq within and makes it accessible via
dnsmasqCapsGetBinaryPath(). While strictly speaking no caller
necessarily needs canonicalized path, let's find dnsmasq once and
cache the result.
Therefore, when constructing the capabilities structure look up
the binary path. If DNSMASQ already contains an absolute path
then virFindFileInPath() will simply return a copy.
With this code in place, the virFileIsExecutable() check can be
removed from dnsmasqCapsRefreshInternal() because
virFindFileInPath() already made sure the binary is executable.
But introducing virFindFileInPath() means we have to mock it in

When -device is configured via JSON a bug [1] is triggered in qemu were
the DEVICE_DELETED event for the removal of the device frontend is no
longer delivered to libvirt. Without the DEVICE_DELETED event we don't
remove the corresponding entries in the VM XML.
Until qemu will be fixed we must stop using the JSON syntax for -device.
This patch removes the detection of the capability. The capability is
used only during startup of a fresh VM so we don't need to consider any
compaitibility steps for existing VMs.
For users who wish to use 'libvirt-7.9' and 'libvirt-7.10' with
'qemu-6.2' there are two possible workarounds:
- filter out the 'device.json' qemu capability '/etc/libvirt/qemu.conf':
capability_filters = [ "device.json" ]
- filter out the 'device.json' qemu capability via qemu namespace XML:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:del capability='device.json'/>
</qemu:capabilities>
</domain>
We must never again use the same capability name as we are now
instructing users to filter it as a workaround so once qemu is fixed
we'll need to pick a new capability value for it.

Until now we did 2 weird things when inserting the qemuCaps used for
individual test cases into the capability cache:
1) we inserted the same caps for all emulators
2) we always (expensively) copied them
Now when real capabilities are used we don't touch them at all just
simply inser them. This allows us one big optimization, by trading a
copy for just a virObjectRef as we can borrow the caps object to the
cache.
For fake caps we still copy them as we insert the fake machine types
into them, but second big optimization is to insert the capabilities
only for the architecture they belong to.
Additionally this commit also ensures that all other entries in the
cache for the binary are poisoned by empty caps so that it's obvious
that the test is doing the right thing.
Apart from this making actually more sense this shaves off more than 40%
of runtime from qemuxml2argvtest.

When libvirt added support for firewalld, all iptables/ebtables rules
were added via the firewalld "passthrough" API when firewalld was
enabled (the "firewalld backend"), or run directly by libvirt when
firewalld was disabled (the so-called "direct
backend"). virfirewalltest.c dutifully ran each test twice, once with
the each backend enabled.
But commit b19863640d changed the code to *always* directly run
iptables/ebtables commands, and never use the firewalld passthrough
API, effectively making the direct and firewalld backends identical,
except that when libvirt receives notice that firewalld has restarted
or reloaded its rules, the firewalld backend sends an extra "iptables
-V" command via firewalld's passthrough API (and waits for a response)
prior to running all the rest of the iptables commands directly; this
assures that a newly-restarted firewalld has finished its work on the
filter tables before libvirt starts messing with it. (Because this
code is only executed in response to an event from dbus, it isn't
tested in the unit tests).
In spite of this, we still go through all the virfirewall tests twice
though - once for the direct backend, and once for the firewalld
backend, even though these take the same codepath.
In commit b19863640d I had left this double-testing in thinking that
someday we might go back to actually doing something useful with the
firewalld backend in the course of adding support for native nftables,
but I've now realized that for the case of nftables we will be *even
more* divorced from firewalld, so there is really no point in keeping
this code around any longer. (It's likely/probable that the tests will
be done twice again in the future, but it will be enough different
that it is better to remove this code and re-implement from scratch
when adding the nftables backend, rather than trying to directly
modify the existing code and end up with something even more
confusing).
This patch eliminates all the test duplication in virfirewalltest.c,
including mocking dbus, which is unnecessary since none of the tests
use dbus (for now we ensure that by explicitly setting the virfirewall
backend to DIRECT before any of the tests have run. Eventually the
concept of a "firewalld backend" will disappear completely, but that's
for another patch.)
