[PATCH] tests: Enable virpcimock on macOS
by Roman Bolshakov 31 Oct '20

31 Oct '20

In general, it has little sense to use Linux pci mock on macOS but virPCIDeviceAddressGetIOMMUGroupNum() is relying on the filesystem layout mocked by virpcimock. And all tests that rely on correct execution of virPCIDeviceAddressGetIOMMUGroupNum() fail. Additionally, missing initialization is added to close() to avoid invocation of real_close() before it's set up. The change fixes qemuhotplugtest, qemumemlocktest and qemuxml2xmltest.

[PATCH] docs/system: Deprecate raspi2/raspi3 machine aliases
by Philippe Mathieu-Daudé 31 Oct '20

31 Oct '20

Since commit aa35ec2213b ("hw/arm/raspi: Use more specific machine names") the raspi2/raspi3 machines have been renamed as raspi2b/raspi3b. As more Raspberry Pi 2/3 models are emulated, in order to avoid confusion deprecate the raspi2/raspi3 machine aliases.

Entering freeze for libvirt-6.9.0
by Jiri Denemark 30 Oct '20

30 Oct '20

I have just tagged v6.9.0-rc1 in the repository and pushed signed tarballs and source RPMs to https://libvirt.org/sources/ Please give the release candidate some testing and in case you find a serious issue which should have a fix in the upcoming release, feel free to reply to this thread to make sure the issue is more visible. If you have not done so yet, please update NEWS.rst to document any significant change you made since the last release. Thanks, Jirka

[libvirt PATCH] tests: fix stat mocking with Fedora rawhide
by Daniel P. Berrangé 30 Oct '20

30 Oct '20

GLibC has a really complicated way of dealing with the 'stat' function historically, which means our mocks in turn have to look at four different possible functions to replace, stat, stat64, __xstat, __xstat64. In Fedora 33 and earlier: - libvirt.so links to __xstat64 - libc.so library exports stat, stat64, __xstat, __xstat64 - sys/stat.h header exposes stat and __xstat In Fedora 34 rawhide: - libvirt.so links to stat64 - libc.so library exports stat, stat64, __xstat, __xstat64 - sys/stat.h header exposes stat Historically we only looked at the exported symbols from libc.so to decide which to mock. In F34 though we must not consider __xstat / __xstat64 though because they only existance for binary compatibility. Newly built binaries won't reference them. Thus we must introduce a header file check into our logic for deciding which symbol to mock. We must ignore the __xstat / __xstat64 symbols if they don't appear in the sys/stat.h header, even if they appear in libc.so Signed-off-by: Daniel P.

[PATCH] rpm: Fix handling of SOURCE_DATE_EPOCH
by Neal Gompa 29 Oct '20

29 Oct '20

Contemporary versions of Fedora automatically set SOURCE_DATE_EPOCH based on the changelog entry date stamp. In scenarios where it already is defined, we do not want to redefine it. Additionally, when building the libvirt package in an Open Build Service instance, the spec file is not present in %_specdir, but instead in %_sourcedir.

[PATCH 0/3] qemu: sync backing chain update in virDomainGetBlockJobInfo
by Nikolay Shirokovskiy 29 Oct '20

29 Oct '20

The issue is desciribed in detail in last patch. I've already tried to address it in [1]. It was not good at all. Actually it was waiting for event processing in worker thread but that processing blocked by qemuDomainGetBlockJobInfo itself holding the job. Now with help of the 1st patch the block job event offloaded to the worker thread can be processed in qemuDomainGetBlockJobInfo.

question regarding systemd ordering of libvirt services
by Jim Fehlig 29 Oct '20

29 Oct '20

Hi All, I'm not sure if the following problem is in systemd or libvirt. When restarting services and sockets *and* libvirt-guests.service is running, the latter will sometimes hang when trying to connect to libvirtd. Even though libvirt-guests has 'Wants=libvirtd.service' and 'After=libvirtd.service', we can see via journalctl that it is not shutdown before libvirtd when executing something like systemctl try-restart libvirtd.service libvirtd.socket libvirtd-ro.socket virtlockd.service virtlockd.socket virtlogd.service virtlogd.socket virt-guest-shutdown.target Oct 28 15:53:31 systemd[1]: Stopping Virtualization daemon...

[PATCH] Revert "spec: Simplify setting features off by default"
by Neal Gompa 29 Oct '20

29 Oct '20

As it turns out, the rather complicated structure that is currently used for enabling or disabling features in the libvirt build does not cleanly map well to RPM's bcond feature. Consequently, we need these back in order to support trivially activating these features through extra macros as build inputs. This reverts commit 31d687a3218c9072d7050dd608e013e063ca180f.
