Qemu 8.1.0 will add discard_no_unref option for qcow2 images.
When this option is enabled (default=false), then it will no longer
unreference clusters when guest does a discard, but it will just free
the blocks (useful for incremental backups for example) and pass the
discard to the lower layer.
This was implemented to avoid fragmentation within the qcow2 image.

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.

The type='pty' attribute in the <serial> element causes a Pseudo TTY to be
allocated on the host side via "/dev/ptmx", which is meant to be
interacted with via "virsh console" or similar.
That's not how a firmware log is typically viewed or saved. Replace
type='pty' with type='file', and also provide an example <source> element
(with the pathname of the logfile), similarly to how the <serial> example
just above provides a <source> element too.

The <serial> opening tag is paired with the </console> closing tag; that's

Per section "Relationship between serial ports and consoles", <serial> is
used for emulated (not paravirt) consoles, and it's the type that's
suitable for early debug output (such as from firmware). Thus, change
</console> to </serial>.
