When starting a domain, it's done so in two steps (actually more,
but lets focus on just the following two):
1) qemuProcessPrepareDomain(), followed by
2) qemuProcessPrepareHost().
Now, in the first step (PrepareDomain()), PCI backends for all
hostdevs is set (qemuProcessPrepareDomain() ->
qemuProcessPrepareDomainHostdevs() -> qemuDomainPrepareHostdev()
-> qemuDomainPrepareHostdevPCI()). Perfect.
But then, additional hostdevs may appear, because in the host
prepare phase we may insert some hostdevs into domain definition
(qemuProcessPrepareHost() -> qemuProcessNetworkPrepareDevices()).
Now, these additional hostdevs don't undergo the same prepare as
hostdevs that were already present in the domain definition (i.e.
in qemuProcessPrepareDomain() phase). Therefore, we have to call
corresponding prepare function explicitly.
NB, the interface hotplug code (qemuDomainAttachNetDevice()) does
not suffer from this problem, because it calls top level
qemuDomainAttachHostDevice() which is used to hotplug regular
hostdevs too and as such calls qemuDomainPrepareHostdev().

- added Alpine 3.17 and 3.18 targets
- dropped Alpine 3.15 and 3.16
Note that we're not actively testing all Alpine targets due to CI

It's almost like we've anticipated this. Our XML parser and

element completely independent of each other. And as of commit

too. All that's left is generate the cmd line according to this

We allow (some) domain devices to have a different <seclabel/>
than the top level domain one (this is mostly to allow access to
a resource for multiple domains). Now, we do couple of sanity
checks for such <seclabel/>, e.g. when the <label/> is specified,
but '@relabel' is set to no. But what we are missing is the
opposite: when '@relabel' is set, but no <label/> was provided.
Our schema already denies such combination. Make our parser
behave the same.

After a QEMU domain is started, among other thing we query memory
device information. And while memory address is returned by QEMU
for all models, we store it only for DIMMs and NVDIMMs. Do store
it for VIRTIO_MEM and VIRTIO_PMEM too.
This effectively reports the address the virtio-mem/virtio-pmem
is mapped to in live XML.

Both virtio-mem and virtio-pmem devices have '.memaddr' attribute
which controls the address where they are mapped in the guest
memory. Ideally, users do not need to specify this as QEMU does
the right thing and computes addresses automatically on startup.
But soon, we will need to record this address as it is part of
guest ABI. And also, there might be some users that want to
control this value. Now, we are in a bit of a pickle, because
both these device types already have a PCI address, therefore we
can't just use <address/> blindly. But what we can do, is
introduce <address/> under the <target/> element. This is also
more conceptual, as knobs under <target/> control guest visible
config of memory device (and .memaddr surely falls into that
category).
NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr
attribute, but because of the way we build cmd line there's no
(easy) way to set the attribute. So ignore that for now.

We have plenty of generic typedefs (that basically just alias a
struct, or our popular virXXXPtr). Because we do not generate
HTML docs for it, the documentation is placed at random places,
e.g.: comment from virDomainPtr typedef ("a virDomainPtr is
pointer to a virDomain private structure ...") ends up after
virDomainProcessSignal enum block.
There are some less weird occurrences of this problem (e.g.
virBlkioParameterPtr), but yet - the typedef appears in TOC.
Therefore, generate a block for each typedef and put its
description there.

of host NUMA nodes, but the memory that's about to be hotplugged
requires memory from a host NUMA node that's not in the set we
need to allow emulator thread to access the node, temporarily.
