[libvirt] [PATCH libvirt] tests: run virshtest independent of current pwd
by Bjoern Walk 13 Feb '18

13 Feb '18

virshtest execves the virsh binary. Make sure that it finds the binary's location independent of the current working directory by specifying the absolute path as determined by the build environment.

[libvirt] [RFC] virSysinfo: Introduce SMBIOS type 3 support
by Zhuangyanying 13 Feb '18

From: Zhuang Yanying <ann.zhuangyanying(a)huawei.com> Some applications inside VM need to access SMBIOS Chassis Asset Tag, which should be emulated.

[libvirt] [PATCH 00/11] Fixes and improvements to feature handling
by Andrea Bolognani 13 Feb '18

13 Feb '18

This series is the result of shaving many a yak while implementing support for pSeries optional features (first attempt at [1], respin coming right after I send this). Quick summary of the changes: * handle more sanely cases where the GIC capability has been enabled but no GIC version has been provided; * use the switch construct more, so that the compiler can warn us when we forget to handle some feature; * where possible (eg. the value is mandatory and there is only a limited number of options to choose from) avoid storing whether a feature is enabled and its actual value separately. Save for the first one, none of the changes should be visible to the user, but they will hopefully improve things for developers.

[libvirt] [PATCH] Fix build with GCC 8 new warnings
by Daniel P. Berrangé 13 Feb '18

13 Feb '18

GCC 8 added a -Wcast-function-type warning to -Wextra by default. This complains if you try to explicitly cast one function signature to another function signature with incompatible args. This is something we do many times in libvirt especially with event callbacks. The hack to silence the warning requires casting via a void(*)(void) signature before casting to the desired type. This gross, so we just disable this new warning. GCC 8 also became more fussy about detecting switch fallthroughs. First it doesn't like it if you have a fallthrough attribute that is not before a case statement. e.g. FOO: BAR: WIZZ: ATTRIBUTE_FALLTHROUGH; Is unacceptable as there's no final case statement, so while FOO & BAR are falling through, WIZZ is not falling through. IOW, GCC wants us to write FOO: BAR: ATTRIBUTE_FALLTHROUGH; WIZZ: Second, it will report risk of fallthrough even if you have a case statement for every single enum value, but only if the switch is nested inside another switch and the outer case statement has no final break. This is is arguably valid because despite the fact that we have cast from "int" to the enum typedef, nothing guarantees that the variable we're switching on only contains values that have corresponding switch labels. e.g. int domstate = 87539319; switch ((virDomainState)domstate) { ... } will not match enum value, but also not raise any kind of compiler warning. So it is right to complain about risk of fallthrough if no default: is present. Signed-off-by: Daniel P.

Interested in fixing mismatches between function parameter names in declarations (header files) and definitions (.c files)? This is a cosmetic / redability fix and does not change functionality. This is patch 1 of larger set of 22 patches that fix parameter names across the libvirt source code. If there is interest I can send the entire patch set. These are cosmetic redability fixes automatically generated by clang-tidy. make check and make syntax-check pass successfully after the 22 patches are applied. This is my first submission so please point out any issues and I will be glad to fix.

[libvirt] Google Summer of Code 2018
by Michal Privoznik 12 Feb '18

12 Feb '18

Dear list, Libvirt has been accepted to this year's GSoC. Yay! For those interested in mentoring let me know (if you haven't already). For those interested in participating as students now it's the best time to view our ideas page [1] and contact corresponding mentors. If you have your own idea that's even better! Let me know and we will find you a mentor. Also, it might be worth reading page dedicated to this year's run [2].

[libvirt] [PATCH 00/14] Basic implementation of persistent reservations
by Michal Privoznik 12 Feb '18

12 Feb '18

QEMU added support for SCSI persistent reservations. The way QEMU implemented that makes it slightly harder for libvirt to adapt to - it's a small binary that needs to start before qemu so that it can connect to it. Basically, what libvirt does is: 1) start qemu-pr-helper (the small binary from above), 2) records its PID for tracking purposes 3) start qemu and when shutting down a domain the process is reversed: 1) shut down qemu process, 2) kill qemu-pr-helper (PID was saved earlier). Now, here also lies the last missing piece to he puzzle - what if qemu-pr-helper dies while qemu is running? After some discussion with Paolo it was agreed that qemu will emit an event for libvirt so that we can respawn the process. Anyway, that shouldn't be a show stopper for these patches (if it was the patch set might get too big). Please test, review and comment. As usual, you can find the patches on my github too: https://github.com/zippy2/libvirt/tree/pr Michal Privoznik (14): virstoragefile: Introduce virStoragePRDef qemuDomainDiskChangeSupported: Deny changing reservations qemu: Introduce pr-manager-helper capability qemu_domain: Introduce qemuDomainDiskPRObject qemu: Generate alias for pr-helper qemu: Store prAlias and prPath in status XML qemu: Generate cmd line at startup qemu: Introduce pr_helper to qemu.conf qemu: Start PR daemons on domain startup qemu: Track PR daemons PIDs in status XML qemu_domain: Introduce qemuDomainGetPRUsageCount qemu_process.c: Introduce qemuProcessSetupPRDaemon qemu_hotplug: Hotplug of reservations qemu_hotplug: Hotunplug of reservations docs/formatdomain.html.in | 25 +- docs/schemas/domaincommon.rng | 19 +- docs/schemas/storagecommon.rng | 34 ++ m4/virt-driver-qemu.m4 | 5 + src/conf/domain_conf.c | 36 ++ src/libvirt_private.syms | 4 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 4 + src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 59 +++ src/qemu/qemu_conf.c | 7 +- src/qemu/qemu_conf.h | 1 + src/qemu/qemu_domain.c | 435 ++++++++++++++++++++- src/qemu/qemu_domain.h | 29 ++ src/qemu/qemu_hotplug.c | 110 ++++++ src/qemu/qemu_process.c | 160 ++++++++ src/qemu/qemu_process.h | 4 + src/qemu/test_libvirtd_qemu.aug.in | 1 + src/util/virstoragefile.c | 166 ++++++++ src/util/virstoragefile.h | 17 + .../disk-virtio-scsi-reservations-not-managed.args | 28 ++ .../disk-virtio-scsi-reservations-not-managed.xml | 40 ++ .../disk-virtio-scsi-reservations.args | 29 ++ .../disk-virtio-scsi-reservations.xml | 38 ++ tests/qemuxml2argvtest.c | 8 + .../disk-virtio-scsi-reservations-not-managed.xml | 1 + .../disk-virtio-scsi-reservations.xml | 1 + tests/qemuxml2xmltest.c | 4 + 29 files changed, 1250 insertions(+), 19 deletions(-) create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations-not-managed.args create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations-not-managed.xml create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations.args create mode 100644 tests/qemuxml2argvdata/disk-virtio-scsi-reservations.xml create mode 120000 tests/qemuxml2xmloutdata/disk-virtio-scsi-reservations-not-managed.xml create mode 120000 tests/qemuxml2xmloutdata/disk-virtio-scsi-reservations.xml -- 2.13.6
