[PATCH 0/9] Configurable policy for handling unstable interfaces
by Markus Armbruster 02 Nov '21

02 Nov '21

Option -compat lets you configure what to do when deprecated interfaces get used. This series extends this to unstable interfaces. Works the same way. Intended for testing users of the management interfaces. It is experimental. To make it possible, I replace the "x-" naming convention by special feature flag "unstable". See PATCH 1 for rationale. Based on my "[PATCH v4 0/5] qapi: Add feature flags to enum members" Based-on: Message-Id: <20211025042405.3762351-1-armbru(a)redhat.com> Markus Armbruster (9): qapi: New special feature flag "unstable" qapi: Mark unstable QMP parts with feature 'unstable' qapi: Eliminate QCO_NO_OPTIONS for a slight simplification qapi: Tools for sets of special feature flags in generated code qapi: Generalize struct member policy checking qapi: Generalize command policy checking qapi: Generalize enum member policy checking qapi: Factor out compat_policy_input_ok() qapi: Extend -compat to set policy for unstable interfaces docs/devel/qapi-code-gen.rst | 9 +- qapi/block-core.json | 123 +++++++++++++++++------- qapi/compat.json | 6 +- qapi/migration.json | 35 +++++-- qapi/misc.json | 6 +- qapi/qom.json | 11 ++- include/qapi/compat-policy.h | 7 ++ include/qapi/qmp/dispatch.h | 6 +- include/qapi/util.h | 8 +- include/qapi/visitor-impl.h | 6 +- include/qapi/visitor.h | 17 +++- monitor/misc.c | 7 +- qapi/qapi-forward-visitor.c | 16 +-- qapi/qapi-visit-core.c | 41 ++++---- qapi/qmp-dispatch.c | 57 ++++++++--- qapi/qmp-registry.c | 4 +- qapi/qobject-input-visitor.c | 22 ++--- qapi/qobject-output-visitor.c | 13 ++- storage-daemon/qemu-storage-daemon.c | 3 +- qapi/trace-events | 4 +- qemu-options.hx | 20 +++- scripts/qapi/commands.py | 12 +-- scripts/qapi/events.py | 10 +- scripts/qapi/gen.py | 13 +++ scripts/qapi/schema.py | 11 ++- scripts/qapi/types.py | 22 +++-- scripts/qapi/visit.py | 14 +-- tests/qapi-schema/qapi-schema-test.json | 7 +- tests/qapi-schema/qapi-schema-test.out | 5 + 29 files changed, 353 insertions(+), 162 deletions(-) -- 2.31.1

[PATCH] virsh: Fix ambiguous output in metadata-change event
by Han Han 02 Nov '21

02 Nov '21

When you set metadata with type element like the following: dom.setMetadata(libvirt.VIR_DOMAIN_METADATA_ELEMENT, "<test/>", 'abc', "HAHAH", 0) Then for `virsh event --all`, then it will output this message: event 'metadata-change' for domain 'rhel9': element HAHAH The message is ambiguous since it looks like the params for metadata-change event is the element HAHAH. Actually that means the type is element while the url is HAHAH. Let's make it more clear.

[PATCH] qemu: tpm: Enable creation of certs for TPM 1.2 in non-privileged mode
by Stefan Berger 01 Nov '21

01 Nov '21

When 'swtpm_setup --print-capabilities' shows the 'tpm12-not-need-root' flag, then it is possible to create certificates for the TPM 1.2 also in non-privileged mode since swtpm_setup doesn't need tcsd anymore. Check for this flag and create the certificates if this flag is found.
