[libvirt] [PATCHv2 00/16] Introduce hvf domain type for Hypevisor.framework
by Roman Bolshakov 18 Dec '18

18 Dec '18

Hypervisor.framework provides a lightweight interface to run a virtual cpu on macOS without the need to install third-party kernel extensions (KEXTs). It's supported since macOS 10.10 on machines with Intel VT-x feature set that includes Extended Page Tables (EPT) and Unrestricted Mode. QEMU supports Hypervisor.framework since 2.12. The patch series adds "hvf" domain that uses Hypevisor.framework. v1: https://www.redhat.com/archives/libvir-list/2018-October/msg01090.html Changes since v1: - [x] Fixed unconditional addition of KVM CPU models into capabilities cache. That fixed a "make check" issue in qemucapabilitiestest on Linux. - [x] Fixed missing brace in virQEMUCapsFormatCPUModels in PATCH 6 - [x] Squashed patch 12 into the first patch (second one in the patch series) - [x] Added hvf domain definition to docs/formatdomain.html.in into the first patch (second in the patch series) - [x] Removed redundant argument in virQEMUCapsProbeHVF (patch 3) - [x] Added separate virQEMUCapsProbeHVF for non-apple platforms (patch 3) - [x] Added macOS support page - [x] Marked HVF support for all working domain elements I wasn't able to resolve the issues below, but I think they should go into separate patches/patch series: - [ ] To make qemucapabilitiestests work regardless of OS, accelerator probing should be done via QMP command. So, there's a need to add a new generic command to QEMU "query-accelerator accel=NAME" - [ ] VIRT_TEST_PRELOAD doesn't work on macOS. There are a few reasons: * DYLD_INSERT_LIBRARIES should be used instead of LD_PRELOAD * -module flag shouldn't be added to LDFLAGS in tests/Makefile.am. The flag instructs libtool to creates bundles (MH_BUNDLE) instead of dynamic libraries (MH_DYLIB) and unlike dylibs they cannot be preloaded. * Either symbol interposing or flat namespaces should be used to perform overrides of the calls to the mocks. I've tried both but neither worked for me, need to make a minimal example. I haven't completed the investigation as it looks like a separate work item. - [ ] Can't retrieve qemucapsprobe replies for macOS because qemucapsprobemock is not getting injected because of the issue with VIRT_TEST_PRELOAD - [ ] Can't add to tests/qemuxml2argvtest.c to illustrate the hvf example because qemucapsprobe doesn't work yet.

[libvirt] [PULL 31/31] hw/i386: Remove deprecated machines pc-0.10 and pc-0.11
by Michael S. Tsirkin 18 Dec '18

18 Dec '18

From: Thomas Huth <thuth(a)redhat.com> They've been deprecated for two releases and nobody complained that they are still required anymore, so it's time to remove these now. And while we're at it, mark the other remaining old 0.x machine types as deprecated (since they can not properly be used for live-migration anyway).

[libvirt] [PATCH] util: fix translation of error message strings
by Daniel P. Berrangé 17 Dec '18

17 Dec '18

The arguments to the N_() macro must only ever be a literal string. It is not possible to use macro arguments, or use macro string concatenation in this context. The N_() macro is a no-op whose only purpose is to act as a marker for xgettext when it extracts translatable strings from the source code. Anything other than a literal string will be silently ignored by xgettext. Unfortunately this means that the clever MSG, MSG2 & MSG_EXISTS macros used for building up error message strings have prevented any of the error messages getting marked for translation. We must sadly, revert to a more explicit listing of strings for now. Signed-off-by: Daniel P.

[libvirt] [PATCH 00/10] error: Refactor error message string convertor and add tests
by Peter Krempa 17 Dec '18

17 Dec '18

Make sure that all the error messages have both versions (info and non-info) and store them in a sorted array rather than a giant switch. Patch 7/10 adds a test that ensures that no messages were harmed during the refactor. That commit will not be pushed (along with the corresponding revert) to avoid polluting git history. Peter Krempa (10): include: error: Add enum sentinel for virErrorNumber enum util: error: Fix error message strings to play well with additional info util: error: Add error message versions with info for some error codes util: error: Export virErrorMsg for use in testsuite tests: Add test for virErrorMsg message constraints util: error: Improve docs for virErrorMsg DO NOT PUSH: Make sure that error messages are not moved around util: error: Use a more declarative approach in virErrorMsg Revert "DO NOT PUSH: Make sure that error messages are not moved around" tests: virerror: Make sure that error messages stay in correct order include/libvirt/virterror.h | 5 + src/Makefile.am | 1 + src/libvirt_private.syms | 2 + src/util/Makefile.inc.am | 1 + src/util/virerror.c | 791 +++++++++--------------------------- src/util/virerrorpriv.h | 36 ++ tests/Makefile.am | 6 + tests/virerrortest.c | 121 ++++++ 8 files changed, 361 insertions(+), 602 deletions(-) create mode 100644 src/util/virerrorpriv.h create mode 100644 tests/virerrortest.c -- 2.19.2

[libvirt] [jenkins-ci PATCH] guests: Fix duplicated key in vault
by Andrea Bolognani 17 Dec '18

17 Dec '18

Commit d3904591a2d2 added the Jenkins secret for FreeBSD 12 to the vault, but mistakenly created a second entry for the existing libvirt-freebsd-11 key instead of introducing a new entry for the libvirt-freebsd-12 key.

[libvirt] [PATCH v3] Drop UML driver

The driver is unmaintained, untested and severely broken for quite some time now. Since nobody even reported any issue with it let us drop it.
