Container build failures for cross-builds on debian-11
by Martin Kletzander
Weekly container builds fail for almost 2 months now (last passed
container build was on 2nd of September) due to debian-11 being probably
broken when installing cross-arch packages. Debian 12 was released at
the 10th of June 2023, so we support debian-11 for 7 more months. But
the cross-builds are probably going to fail for all those 7 months.
Since that spoils the view of the pipelines I would suggest we remove
the cross-architecture builds for debian-11 since we're still testing
them on debian-12 and that works nicely. We would still keep x86_64 and
i686 debian-11 builds there of course. Is anyone opposed to that or is
there any clear issue with the above suggestion?

[PATCH 00/32] Add support for versioned CPU models
by Jiri Denemark
When parsing a domain XML which uses a non-versioned CPU model we want
to replace it with the appropriate version variant similarly to what we
do with machine types. Theoretically QEMU supports per machine type
specification of a version with which a non-versioned CPU model is
replaced, but this is always 1 for all machine types and the
query-machines QMP command does not even report the value.
Luckily after talking to Igor, having a single number per machine type
does not really allow for setting it to anything but 1 as CPU models
have different number of versions. Each machine type would need to
define a specific version for each CPU model, which would be a
maintenance nightmare. For this reason there's no desire to ever resolve
non-versioned CPU models to anything but v1 in QEMU and the per machine
type setting will most likely even be removed completely. Thus it is
safe for us to always use v1 as the canonical CPU model.
Some non-versioned CPU models, however, are actually aliases to specific
versions of a base model rather than being base models themselves. These
are the old CPU model variants before model versions were introduced,
e.g., -noTSX, -IBRS, etc. The mapping of these names to versions is
hardcoded and will never change. We do not translate such CPU models to
the corresponding versioned names. This allows us to introduce the
corresponding -v* variants that match the QEMU models rather than the
existing definitions in our CPU map. The guest CPU will be the same
either way, but the way libvirt checks the CPU model compatibility with
the host will be different. The old "partial" check done by libvirt
using the definition from CPU map will still be used for the old names
(we can't change this for compatibility reasons), but the corresponding
versioned variants (as well as all other versions that do not have a
non-versioned alias) will benefit from the recently introduced new
"partial" check which uses only the information we get from QEMU to
check whether a specific CPU definition is usable on the host.
Other I considered were:
- replace -noTSX, -IBRS, ... models with their versioned variants
- we'd need to translate them back for migration (just what we do
for -v1) for backward compatibility
- I found the benefit of new partial checking when explicitly using
the versioned variants quite appealing and dropped the relevant
changes in progress
- do not translate anything, i.e., not even base models to -v1
- the idea behind translating was to make sure QEMU suddenly doesn't
start translating the base CPU model to a different version (this
does not happen with -noTSX etc. as they are hardcoded aliases);
Igor said they will never do that so is this still valid?
- not translating would bring the same benefit of explicitly using
-v1 vs non-versioned name
I guess the current mix does not look very consistent (i.e., it's not
either all or nothing), but it makes sense to me. The question is
whether it also makes sense to others :-)

[libvirt PATCH] docs: document external swtpm
by Ján Tomko
When external swtpm support was added back in 9.0.0, I omitted
the update of the XML docs.
Add it now, especially since the 'emulator' backend can now
also use the <source> element.

absolutely not sure about this idea so feel free to comment.
