'&authdef->secdef'
Note that a username may be NULL.

Rather than assume/pass the protocol to the qemuDomainSecretPlainSetup
and qemuDomainSecretAESSetup, set and pass the secretUsageType based
on the src->protocol type. This will eventually be used by the
virSecretGetSecretString call

This kvmGetMaxVCPUs() needs to be used at two different places
so move it to utils with appropriate name and mark it as private
global now.

On PPC the legacy passthrough is not supported and only
VFIO is supported. So, the checks at places to confirm if the
host is passthrough capable checks only legacy, fix it. This
is seen at only one place now.

Unfortunately, we can't just call qemuDomainMachineIsPSeries()
here, because we don't have a virDomainDef instance; that said,
the open-coded check should match said function as closely as
possible.
The directories we iterate over are unlikely to contain any entries
starting with a dot, other than '.' and '..' which is already skipped
by virDirRead.
Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.
This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

One can not issue monitor commands manually during async calls thru
designated API while this could be useful for testing/debugging purposes.
qemuDomainQemuMonitorCommand uses job of type QEMU_JOB_MODIFY and any async
call disable parallel execution of this type of job. The only state that is
changed is taint variable. AFAIU the only place we can mess is resetting
taint flag in qemuProcessStop routine under some async job. But this can not
happen thanx to both virDomainObjIsActive check in qemuDomainQemuMonitorCommand
and resetting active status in qemuProcessStop before taint flag.
Change job type to QEMU_JOB_QUERY and thus make the API call available for
most of async jobs.

We should not require any parameters to be present. After all we have
the *_set bools to express that some parameters were not set.

qemuMonitorMigrationParams is a better name for a structure which
contains various migration parameters. While doing that, we should use
full names for individual parameters.

Checking whether the function has anything to do is better done in the

Allow gathering available vcpu ids, their state and offlinability via
the qemu guest agent. The maximum id was chosen arbitrarily and ought
to be enough for everybody.
Documentation for the "guest-set-vcpus" command describes a proper
algorithm how to set vcpus. This patch makes the following changes:
- state of cpus that has not changed is not updated
- if the command was partially successful the command is re-tried with
the rest of the arguments to get a proper error message
- code is more robust against malicious guest agent
- fix testsuite to the new semantics
So far this is only useful for recalculating NUMA memory size,
which this function cannot parse.
This will let us generate USB addresses based on this flag.
The '-usb' option doesn't have any effect for aarch64 mach-virt
guests, so the fact that it's currently enabled by default is not
really causing any issue.
However, that might change in the future (although unlikely), and
having it as part of the QEMU command line can cause confusion to
someone looking through the process list.
Avoid it completely, like it's already happening for q35.
There has been some progress lately in enabling virtio-pci on
aarch64 guests; however, guest OS support is still spotty at best,
so most guests are going to be using virtio-mmio instead.
Currently, mach-virt guests are closely modeled after q35 guests,
and that includes always adding a dmi-to-pci-bridge that's just
impossible to get rid of. While that's acceptable (if suboptimal)
for q35, where you will always need some kind of PCI device anyway,
mach-virt guests should be allowed to avoid it.
While we need to know the difference between the total memory stored in
<memory> and the actual size not included in the possible memory modules
we can't pre-calculate it reliably. This is due to the fact that
libvirt's XML is copied via formatting and parsing the XML and the
initial memory size can be reliably calculated only when certain
conditions are met due to backwards compatibility.
This patch removes the storage of 'initial_memory' and fixes the helpers
to recalculate the initial memory size all the time from the total
memory size. This conversion is possible when we also make sure that
memory hotplug accounts properly for the update of the total memory size
and thus the helpers for inserting and removing memory devices need to
be tweaked too.
This fixes a bug where a cold-plug and cold-remove of a memory device
would increase the size reported in <memory> in the XML by the size of
the memory device. This would happen as the persistent definition is
copied before attaching the device and this would lead to the loss of
data in 'initial_memory'.
