[PATCH v1 00/10] capabilities: Expose HMAT
by Michal Privoznik
We allow configuring HMAT for domains since v6.6.0-rc1~249 (and
friends). Basically, HMAT is more fine grained description of
interconnects of NUMA nodes than basic NUMA distances. The former
describes bandwidths and latencies while the latter is some
dimensionless and normalized number.
Anyway, mgmt apps did not really know what values to set for HMAT
because we are not exposing them in capabilities because we were waiting
on kernel to expose them. And it just did.
In 09/10 I'm describing sysfs interface briefly and also mention that
there's no interpretation of links to memory side caches, yet. I'm
talking to kernel developers so we might get some movement there. But
also, I'm not sure whether it's worth the effort OR if there really is a
machine that has separate links to main memory and caches.
Here's link to ACPI spec:
https://uefi.org/sites/default/files/resources/ACPI_6_2.pdf
Look for "5.2.27.4 System Locality Latency and Bandwidth Information
Structure".
And here's link to sysfs docs:

[PATCH] tools: only fail validations if VIR_HOST_VALIDATE_FAIL is set
by Fabiano Fidêncio
Currently `virt-host-validate` will fail whenever one of its calls fail,
regardless of virHostValidateLevel set.
This behaviour is not optimal and makes it not exactly reliable as a
command line tool as other tools or scripts using it would have to check
its output to figure out whether something really failed or if a warning
was mistakenly treated as failure.
With this change, the behaviour of whether to fail or not, is defined by
the caller of those functions, based on the virHostValidateLevel passed
to them.

Libvirt CI for running functional tests
by Praveen K Paladugu
Hi,
While developing cloud-hypervisor driver for libvirt, we re-fitted
cloud-hypervisor project's CI to libvirt. This CI was built on Rust and
currently supports VM boot up tests.
https://github.com/cloud-hypervisor/libvirt/tree/ch/ch_integration_tests
We are working on extending this CI to incorporate more functional
tests: Networking, Thread Pinning etc. We are curious to know if libvirt
project has any plans to setup a CI to run functional tests.
I noticed https://gitlab.com/libvirt/libvirt-ci effort which focuses on
running builds against various platforms and formats. Could you please
clarify libvirt project's plan for setting up a CI to run functional tests.
Regards,
Praveen K Paladugu

[libvirt PATCH v2] docs: introduce stubs for new libvirt Go packages
by Daniel P. Berrangé
Currently we expose libvirt Go packages at
libvirt.org/libvirt-go
libvirt.org/libvirt-go-xml
These packages have not supported Go modules historically and when we
tried to introduce modules, we hit the problem that we're not using
semver for versioning.
The only way around this is to introduce new packages under a different
namespace, that will have the exact same code, but be tagged with a
different version numbering scheme.
This change proposes:
libvirt.org/go/libvirt
libvirt.org/go/libvirtxml
Note the hyphen is removed so that the import basename matches the
Go package name.

[PATCH 0/3] Replace some libvirt handling functions with GLib APIs
by Luke Yue
Note that the g_find_program_in_path() will search file in current dir
when PATH env is not set, while virFindFileInPath() won't.
The virFileAbsPath() could be replaced by g_canonicalize_file() when not
take the return value into account, and it just simply return 0 now, so
maybe remove the function is a better choice?
Related issue: https://gitlab.com/libvirt/libvirt/-/issues/12
Luke Yue (3):
virfile: Use g_build_filename() when building paths
virfile: Simplify virFindFileInPath() with g_find_program_in_path()
virfile: Use g_canonicalize_file() to simplify virFileAbsPath()
