[libvirt PATCHv2 0/2] virsh: domsetlaunchsecstate: report error if no options are passed
by Ján Tomko 28 Jan '22

28 Jan '22

Use a different approach that is hopefully more future-proof and also add a check to the qemu driver, as suggested by Michal.

[PATCH v2] virProcessGetStatInfo: add a comment describing why we can not report error
by Ani Sinha 28 Jan '22

28 Jan '22

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.

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.

[PATCH v2 0/6] support mode option for dirtyrate calculation
by huangy81＠chinatelecom.cn 27 Jan '22

27 Jan '22

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.
