[libvirt PATCHv2 0/2] virsh: domsetlaunchsecstate: report error if no options are passed
by Ján Tomko
Use a different approach that is hopefully more future-proof and also
add a check to the qemu driver, as suggested by Michal.
Ján Tomko (2):
virsh: domsetlaunchsecstate: report error if no options are passed
qemu: qemuDomainSetLaunchSecurityState: check for params presence

[PATCH v2] virProcessGetStatInfo: add a comment describing why we can not report error
by Ani Sinha
virProcessGetStatInfo() currently is unable to report error conditions because
that breaks libvirt's public best effort APIs. We add a comment in the function
to indicate this. Adding comment here prevents others from going down the path
of reporting error conditions in this functions in the future. It also reminds
us that at some point in the future we need to fix the code so that this
limitations no longer exists.
Please also see commit
105dace22cc7 ("Revert "report error when virProcessGetStatInfo() is unable to parse data"")

Backend memory object creation - query
by M, Shivakumar
Hello,
For our use-case with Libvirt we want to create the Memory backend object ,
Expected QEMU args would be
-object memory-backend-memfd,id=mem1,size=4096M
Request you to please help us to specify this arg in the libvirt XML.
Thanks,

[libvirt PATCH 0/5] meson: Fixes and improvements to handling of qemu_user and qemu_group
by Andrea Bolognani
Mostly reported/suggested by Olaf.
Test pipeline: https://gitlab.com/abologna/libvirt/-/pipelines/456827585
Ignore the macOS failure, which is caused by a transient network
error on GitLab's part. I have verified manually that the default
values are still the ones we expect.
Andrea Bolognani (5):
meson: Don't require /etc/os-release to be present
meson: Check for os-release's ID_LIKE in addition to ID
meson: Don't check whether qemu_user and qemu_group exist
meson: Require that both qemu_user and qemu_group are provided
meson: Optimize handling of qemu_user and qemu_group

[PATCH v2 0/6] support mode option for dirtyrate calculation
by huangy81＠chinatelecom.cn
From: Hyman Huang(黄勇) <huangy81(a)chinatelecom.cn>
v2:
Rebase master and fix confilicts with commit
"Introduce QEMU_CAPS_DEVICE_VIRTIO_MEM_PCI_PREALLOC"
Thanks !
v1:
This patchset introduce mode option as the supplement of
qemuDomainStartDirtyRateCalc api, add calc_mode for dirtyrate
statistics correspondingly.
Qemu add mode parameter for calc-dirty-rate command since >= 6.2.0,
either of these three mode "page-sampling, dirty-bitmap, dirty-ring"
can be specified when calculating dirty page rate.
Page sampling is the original mode and used as default mode.
Dirty bitmap mode use kvm log sync api to fetch the dirty-bitmap
and count the increased 1 bits number during measurement, thus,
calculate the dirty page rate.
Dirty ring mode use the dirty-ring mechanism implemented in Qemu
which can count the increased dirty page on virtual cpu granularity,
thus, calculate the per-vcpu dirty page rate.
These three calculation mode can be used in different scenarios, and
the dirty-bitmap, dirty-ring mode may be more accurate to a certain
degree. So maybe it's time to support the mode option for dirtyrate
calculation.
This series make main modifications as the following:
1. introduce QEMU_CAPS_CALC_DIRTY_RATE capability to probe
calc-dirty-rate command in case of failure since it just
introduced since >= 5.2.0
2. introduce QEMU_CAPS_DIRTYRATE_MODE capability to probe
mode option of calc-dirty-rate command in case of failure, same
as 1.
3. implement mode option support for dirtyrate calculation.
Please review, thanks !
Best Regards !
