[libvirt] [PATCH 1/1] cpu_map.xml: add cmt/mbm feature to x86
by Qiaowei Ren
Some Intel processor families (e.g. the Intel Xeon processor E5 v3
family) introduced some PQos (Platform Qos) features, including CMT
(Cache Monitoring echnology) and MBM (Memory Bandwidth Monitoring),
to monitor or control shared resource. This patch add them into x86
part of cpu_map.xml to be used for applications (like OpenStack)
based on libvirt to get cpu capabilities.

[libvirt] [PATCH 0/2] Warn users with weird thread/memory alignment
by Martin Kletzander
People are doing weird things. Let's let them do what they want but
gently warn them in case they did not want that exact behaviour and
are looking for some possible problems.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1254402

[libvirt] [PATCH] Don't allow raneming domains to empty strings
by Martin Kletzander
It may cause unwanted behaviour (of course, is there any wanted one for
that case?) so we should rather disable the possibility of doing so.

[libvirt] [PATCH 0/3] Add hotplug/unplug for RBD disk with AES secret
by John Ferlan
Since AES secrets were setup for RBD during qemuDomainSecretDiskPrepare,
the secret object needs to be added to the command line when hotplugging.
Additionally, when unplugging, if there's an AES secret, we need to remove it.
John Ferlan (3):
qemu: Remove type from qemuBuildSecretInfoProps
qemu: Make qemuBuildSecretInfoProps global
qemu: Add secinfo for hotplug virtio disk

[libvirt] [libvirt-test-API] Plans for code update
by Ruifeng Bian
I am not sure how many of you keep an eye on this project. The project is for
testing libvirt-python APIs, but many test cases are not fully implemented until
now. We want to keep this project updated in the future, the following aspects
will be considered to update the code:
1. Code style - Use inspekt to check code style.
2. Pythonizing the code - Replace all shell scripts with python.
3. Bug fixing - Some code bugs need to be fixed.
4. New features - Add more API test cases.
Any feedback or suggestion is welcome. Let's work together to contribute
to this project.
Thanks,
Ruifeng Bian

[libvirt] [PATCH 0/4] Add architecture checks to qemuDomainMachineIs*()
by Andrea Bolognani
The pseries machine type is only available on ppc64/ppc64le,
and in the same way the virt machine type is only available
on armv7l/aarch64.
Until either machine type is introduced on another
architecture, we can perform the architecture checks in a
single location instead of repeating them all over the place.
Andrea Bolognani (4):
qemu: Remove redundant arguments to qemuBuildSerialChrDeviceStr()
qemu: Add architecture checks to qemuDomainMachineIsVirt()
qemu: Introduce qemuDomainMachineIsPSeries()
qemu: Use stricter checks in virQEMUCapsFillDomainDeviceDiskCaps()

[libvirt] [RFC PATCH] build: increase xz compression level
by Ján Tomko
Increase the default compression level to 9 from 6.
This also increases decompression memory requirements
from 9 MB to 65 MB.
---
The resulting tarball is 880 kB smaller [10.5 MB]
Level 8 requires 33 MB and saves 520 kB [10.8 MB]
Level 7 requires 17 MB and saves 170 kB [11.2 MB]
Compression time is not much different since we're already using --extreme.
The Linux kernel also uses -9, but the tarball is 8x our size.
