[libvirt PATCH] virt-host-validate: fix detection with cgroups v2
by Pavel Hrdina
Using virtCgroupNewSelf() is not correct with cgroups v2 because the
the virt-host-validate process is executed from from the same cgroup
context as the terminal and usually not all controllers are enabled
by default.
To do a proper check we need to use the root cgroup to see what
controllers are actually available. Libvirt or systemd ensures that
all controllers are available for VMs as well.
This still doesn't solve the devices controller with cgroups v2 where
there is no controller as it was replaced by eBPF. Currently libvirt
tries to query eBPF programs which usually works only for root as
regular users will get permission denied for that operation.

sync_qemu_i386.py in src/cpu_map is a tool to sync CPU models from qemu

* "KnightsMill"
* "Snowridge"
Currently missing x86 CPU features:
* "core-capability"
* "fsrm"
* "split-lock-detect"
"fsrm" is added in this series. For the "Snowridge" CPU model and the
"core-capability" and "split-lock-detect" features, see

I made in commit v6.7.0-302-gd3f3c2c97f. The reasoning is that
if ppc64 NVDIMM alignment can be done in PostParse time, regular
ppc64 DIMMs alignment can also be done the same way. After that
I realized that the same logic can be applied to x86 as well,
and then I started to see where we could eliminate explicit
align calls.
The end result is that a bug that affects pSeries the most
was found and fixed in patch 02, and now we're able to reflect
the exact memory being used by the guest in the live XML since
the alignment is now done in parse time. The series can be
fetched from:
https://gitlab.com/danielhb/libvirt/-/tree/memory_modules_postparse_v1
NOTE: I worked with the x86 logic based on what I could assert
from the code itself, i.e. the aligment mechanics (2MiB align for
mem modules, 1MiB align for total memory) are related to QEMU
internals, not being hypervisor-agnostic. If someone with authority can
guarantee that the alignment restrictions for x86 are applicable
to all hypervisors (like in the pSeries case), let me know and
I'll respin the series putting the x86 code in
virDomainMemoryDefPostParse().

domain_conf.c: handle all ppc64 dimms in
virDomainNVDimmAlignSizePseries
qemu_domain.c: align memory modules before calculating 'initialmem'
domain_conf.c: align pSeries mem modules in
virDomainMemoryDefPostParse()
qemu_domain.c: simplify qemuDomainGetMemoryModuleSizeAlignment()
qemu_domain.c: align x86 memory module in post parse time
qemu_domain.c: move size check for mem modules after alignment
qemu_hotplug.c: avoid aligning the mem obj in
qemuDomainDetachPrepMemory()
qemu_hotplug.c: avoid aligning the mem obj in qemuDomainAttachMemory()

[libvirt PATCH 00/16] docs: add manpages for all the modular daemons
by Daniel P. Berrangé
Most of the modular daemon stuff has been done from a single template,
but for the man pages that is more trouble than it is worth, so we
create a separate man page source for each daemon, which makes it easy
to extend with driver specific information.
Daniel P. Berrangé (16):
docs: consistently mark libvirtd as preformatted text
docs: don't hardcode an ancient version in manpage examples
docs: tweak heading for daemon manual pages
docs: add manpage for virtproxyd
docs: add manpage for virtbhyved
docs: add manpage for virtinterfaced
docs: add manpage for virtlxcd
docs: add manpage for virtnetworkd
docs: add manpage for virtnodedevd
docs: add manpage for virtnwfilterd
docs: add manpage for virtqemud
docs: add manpage for virtsecretd
docs: add manpage for virtstoraged
docs: add manpage for virtvboxd
docs: add manpage for virtvzd
docs: add manpage for virtxend
