Jano probably based his branch on top of mine and didn't notice when I moved the section up slightly and thus git applied it again. Keep only the instance followin the new features section.

[libvirt] [PATCH 00/15] qemu: Add possibility to control qemu capabilities for debug (blockdev-add saga spin-off)
by Peter Krempa 20 Jun '19

20 Jun '19

While this is not strictly required for blockdev to work it was created as a part of the testing (and possibly regression mitigation) effort. These patches introduce the option to add or remove qemu capabilities via the qemu XML namespace custom elements and remove features via qemu.conf. This series depends (very slightly) on the series deleting qemu parsing. To make applying it easy I'd sugges you fetrch everything needed by: git fetch https://github.com/pipo/libvirt.git features-filter Peter Krempa (15): qemu: Rename qemuDomainCmdlineDefPtr to qemuDomainXmlNsDefPtr qemu: Move qemuDomainXmlNsDef(Free) from qemu_conf.(ch) qemu: domain: Use virStringListFreeCount in qemuDomainXmlNsDefFree qemu: Extract parsing of qemu namespace arguments into separate function qemu: Extract parsing of qemu namespace env vars into separate function qemu: Refactor qemuDomainDefNamespaceParse qemu: domain: Split out commandline namespace data formatting conf: Add taint flag for custom hypervisor features qemu: Add support for controling qemu capabilities via the qemu XML namespace qemu: domain: Add support for modifying qemu capability list via qemu namespace tests: qemuxml2argv: Modernize and fork 'qemu-ns' test tests: qemuxml2argv: Test qemu namespace capability tweaking qemu: Remove unused var 'corestr' from virQEMUDriverConfigLoadFile qemu: conf: Add debug option to allow disabling qemu capabilities qemu: Implement support for 'capability_filters' config option docs/drvqemu.html.in | 30 ++ docs/schemas/domaincommon.rng | 19 ++ src/conf/domain_conf.c | 1 + src/conf/domain_conf.h | 1 + src/qemu/libvirtd_qemu.aug | 3 + src/qemu/qemu.conf | 7 + src/qemu/qemu_command.c | 16 +- src/qemu/qemu_conf.c | 39 ++- src/qemu/qemu_conf.h | 17 +- src/qemu/qemu_domain.c | 285 +++++++++++++----- src/qemu/qemu_domain.h | 19 ++ src/qemu/qemu_process.c | 55 ++++ src/qemu/test_libvirtd_qemu.aug.in | 3 + tests/qemuxml2argvdata/qemu-ns.args | 33 -- .../qemu-ns.x86_64-4.0.0.args | 41 +++ .../qemu-ns.x86_64-latest.args | 41 +++ tests/qemuxml2argvdata/qemu-ns.xml | 5 + tests/qemuxml2argvtest.c | 3 +- 18 files changed, 458 insertions(+), 160 deletions(-) delete mode 100644 tests/qemuxml2argvdata/qemu-ns.args create mode 100644 tests/qemuxml2argvdata/qemu-ns.x86_64-4.0.0.args create mode 100644 tests/qemuxml2argvdata/qemu-ns.x86_64-latest.args -- 2.21.0

[libvirt] [PATCH] remote: refactor how unprivileged user session connection is identified
by Daniel P. Berrangé 20 Jun '19

20 Jun '19

Currently the VIR_DRV_OPEN_REMOTE_USER flag is only set when we identify that we're connecting to a local libvirtd daemon. We would like to be able to set that even if connecting to a remote libvirtd daemon. This entails refactoring the conditional check. One subtle change is that the VIR_DRV_OPEN_REMOTE_USER is now set when the test+XXX:// URI is used, even if a servername is present. This has no effect in this patch, but will later.
