[libvirt PATCH] tests: Don't advertise VIR_TEST_EXPENSIVE to users
by Andrea Bolognani 23 Sep '20

23 Sep '20

Right now, the logic that takes care of deciding whether expensive tests should be run or not is not working correctly: more specifically, it's not possible to use something like $ VIR_TEST_EXPENSIVE=1 ninja test to override the default choice, because in meson.build we always pass an explicit value that overrides whatever is present in the environment. We could implement logic to make this work properly, but that would require some refactoring of our test infrastructure and is arguably of little value given that running $ meson build -Dexpensive_tests=enabled is very fast, so let's just stop telling users about the variable instead and call it a day.

[RFC] Add basic driver for the Cloud-Hypervisor
by William Douglas 23 Sep '20

23 Sep '20

This patch adds support for the following initial VM actions using the Cloud-Hypervsior API: * vm.create * vm.delete * vm.boot * vm.shutdown * vm.reboot * vm.pause * vm.resume To use the Cloud-Hypervisor driver, the v0.9.0 (the as of now current) release of Cloud-Hypervisor is required to be installed.

[PATCH 0/2] Add unit test for timer validation
by Sebastian Mitterle 22 Sep '20

22 Sep '20

In v1, the minimal test case is moved to the existing test suite qemuxml2argv. Support for error message checking is added. The error message expectations for existing test cases have not been validated and reflect the current state. Localization suppression was tested manually by running the test suite executable with a different locale that should have made one of the tests fail if it had been localized. Requiring the an expected failure to have an error was tested manually by using the original qemuxml2argvmock that didn't create an error message.

[PATCH v6 0/3] bhyve: support 'isa' controller for LPC
by Roman Bogorodskiy 22 Sep '20

22 Sep '20

Changes since v5: Added patch 3/3 to allow to use slot 1 for devices other than LPC. Technically, it can be squashed into the second patch, but this way it should be easier to review; I can squash it before merging, but I also it's probably self-contained enough to stay separated. No changes in 1-2/3 except rebasing.

[PATCH v1 0/4] revert latest PPC64 NVDIMM changes
by Daniel Henrique Barboza 22 Sep '20

22 Sep '20

Hi, In [1], Daniel pointed out that the changes made by [2] are uncompliant with the Libvirt design of not doing anything that can compromise guests in the wild. This series aims to solve that by reverting the changes made by [2]. It also enhances the auto-alignment of ppc64 NVDIMM in a way that we can have consistency between the sizes reported in the domain XML and what QEMU will see, while not hurting any running guests that are already using the auto-alignment feature. For simplicity, first patch contains the revert of all relevant patches from [2] in a single commit. [1] https://www.redhat.com/archives/libvir-list/2020-September/msg00572.html [2] https://www.redhat.com/archives/libvir-list/2020-July/msg02010.html Daniel Henrique Barboza (4): qemu: revert latest pSeries NVDIMM design changes conf, qemu: move qemuDomainNVDimmAlignSizePseries to domain_conf.c domain_conf.c: auto-align pSeries NVDIMM in virDomainMemoryDefParseXML() NEWS.rst: document the pSeries NVDIMM auto-alignment revival NEWS.rst | 12 ++++ docs/formatdomain.rst | 6 +- src/conf/domain_conf.c | 71 +++++++++++++++---- src/conf/domain_conf.h | 3 + src/libvirt_private.syms | 1 + src/qemu/qemu_domain.c | 19 +++-- src/qemu/qemu_domain.h | 6 +- src/qemu/qemu_hotplug.c | 6 +- src/qemu/qemu_validate.c | 42 ++--------- ...ory-hotplug-nvdimm-ppc64.ppc64-latest.args | 2 +- .../memory-hotplug-nvdimm-ppc64.xml | 2 +- .../memory-hotplug-nvdimm-ppc64.xml | 2 +- 12 files changed, 105 insertions(+), 67 deletions(-) -- 2.26.2

[PATCH] util: support PCI passthrough net device stats collection
by zhenwei pi 22 Sep '20

22 Sep '20

Collect PCI passthrough net device stats from kernel by netlink API. Currently, libvirt can not get PCI passthrough net device stats, run command: #virsh domifstat instance --interface=52:54:00:2d:b2:35 error: Failed to get interface stats instance 52:54:00:2d:b2:35 error: internal error: Interface name not provided The PCI device(usually SR-IOV virtual function device) is detached while it's used in PCI passthrough mode. And we can not parse this device from /proc/net/dev any more. In this patch, libvirt check net device is VF of not firstly, then query virNetDevVFInterfaceStats(new API). virNetDevVFInterfaceStats parses VFs info of all PFs, compares MAC address until the two MAC addresses match. '#ip -s link show' can get the same result. Instead of parsing the output result, implement this feature by libnl API. Notice that this feature deponds on driver of PF. Test on Mellanox ConnectX-4 Lx, it works well. Also test on Intel Corporation 82599ES, it works, but only get 0. (ip-link command get the same result).

[PATCH] tests: avoid close of bad file handle in commandtest

[libvirt PATCH] tests: don't mix FILE* and UNIX FD I/O on same stream
by Daniel P. Berrangé 22 Sep '20

22 Sep '20

There is currently a hand in test27 that exhibits itself on FreeBSD 11.4 only. The behaviour is that virCommandProcessIO gets POLLIN on the FD for stdout, but read() blocks. Meanwhile commandtest also blocks in write for stderr because the pipe buffers are full. This fix in commandhelper likely does not really address the root cause just hides it due to the buffering done by FILE *. Mixing UNIX FD I/O and FILE * I/O is bad practice regardles.

[PATCH v5 0/8] Configurable policy for handling deprecated interfaces
by Markus Armbruster 22 Sep '20

22 Sep '20

New option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<in-policy> configures what to do when deprecated input is received. Available policies: * accept: Accept deprecated commands and arguments (default) * reject: Reject them * crash: Crash -compat deprecated-output=<out-policy> configures what to do when deprecated output is sent. Available output policies: * accept: Emit deprecated command results and events (default) * hide: Suppress them For now, -compat covers only deprecated syntactic aspects of QMP. We may want to extend it to cover semantic aspects, CLI, and experimental features. v5: * Old PATCH 01-26 merged in commit f57587c7d47. * Rebased, non-trivial conflicts in PATCH 1 due to Meson, and in PATCH 7 due to visitor changes * PATCH 1: Comments updated for 5.2 [Eric] * PATCH 2: Harmless missing initialization fixed [Eric] * PATCH 3+4: Harmless missing has_FOO = true fixed [Eric] * PATCH 6+7: Commit message tweaked v4: * PATCH 05+07: Temporary memory leak plugged [Marc-André] * PATCH 23: Rewritten [Marc-André] * PATCH 24: Comment typo [Marc-André] * PATCH 30: Memory leaks plugged v3: * Rebased, non-trivial conflicts in PATCH 01+26+27+34 due to RST conversion and code motion * PATCH 28-29: Old PATCH 28 split up to ease review * PATCH 30-31: New * PATCH 32-33: Old PATCH 29 split up to ease review Comparison to RFC (24 Oct 2019): * Cover arguments and results in addition to commands and events * Half-baked "[RFC PATCH 18/19] qapi: Include a warning in the response to a deprecated command" dropped See also last item of Subject: Minutes of KVM Forum BoF on deprecating stuff Date: Fri, 26 Oct 2018 16:03:51 +0200 Message-ID: <87mur0ls8o.fsf(a)dusky.pond.sub.org> https://lists.nongnu.org/archive/html/qemu-devel/2018-10/msg05828.html Cc: Lukáš Doktor <ldoktor(a)redhat.com> Cc: libguestfs(a)redhat.com Cc: libvir-list(a)redhat.com Cc: Daniel P.

[PATCH v3 0/6] qemu: implementation of transient disk option
by Masayoshi Mizuma 19 Sep '20

19 Sep '20

This patchset tries to implement transient option for qcow2 and raw format disk. It gets user available to set <transient/> to the domain xml file like as: <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/guest.qcow2'/> <target dev='vda' bus='virtio'/> <transient/> </disk> Any changes which the Guest does to the disk is dropped when the Guest is shutdowned. There are some limitations for transient disk option so far: - Supported disk format is qcow2 and raw - blockdev capability is required for qemu - Following features are blocked with transient disk option - blockjobs - Migration - Disk hotplug Masayoshi Mizuma (6): qemu: Block blockjobs when transient disk option is enabled qemu: Block disk hotplug when transient disk option is enabled qemu: Block migration when transient disk option is enabled qemu: update the validation for transient disk option qemu: Introduce to handle transient disk qemu: Add transient disk handler to start and stop the guest src/qemu/qemu_domain.c | 7 +++ src/qemu/qemu_hotplug.c | 6 +++ src/qemu/qemu_migration.c | 10 ++++ src/qemu/qemu_process.c | 10 ++++ src/qemu/qemu_snapshot.c | 103 +++++++++++++++++++++++++++++++++++--- src/qemu/qemu_snapshot.h | 5 ++ src/qemu/qemu_validate.c | 25 ++++++++- src/util/virstoragefile.c | 2 + src/util/virstoragefile.h | 4 ++ 9 files changed, 164 insertions(+), 8 deletions(-) -- 2.27.0
