Re: [libvirt] [PATCH 0/6] Fix guest CPU updates for inactive domains

This series originally started as a cleanup work, but it turned out two real bugs got fixed with this cleanup :-) Since commit v2.2.0-199-g7ce711a30e libvirt stores an updated guest CPU in domain's live definition and there's no need to update it every time we want to format the definition. Thus libvirt should never internally request a guest CPU update when formatting domain XML. But if it is asked by a user to do so, it should use the same host CPU model which is used when starting a domain to provide meaningful results. https://bugzilla.redhat.com/show_bug.cgi?id=1481309 https://bugzilla.redhat.com/show_bug.cgi?id=1485022 Jiri Denemark (6): qemuxml2xmltest: Add tests for Power CPUs cpu_conf: Drop updateCPU from virCPUDefFormat cpu_conf: Simplify formatting of guest CPU attributes conf: Drop unused VIR_DOMAIN_DEF_FORMAT_UPDATE_CPU qemu: Use correct host model for updating guest cpu qemu: Don't update CPU when formatting live def src/bhyve/bhyve_driver.c | 2 +- src/conf/capabilities.c | 2 +- src/conf/cpu_conf.c | 38 +++++++++------------ src/conf/cpu_conf.h | 9 ++--- src/conf/domain_capabilities.c | 2 +- src/conf/domain_conf.c | 6 +--- src/conf/domain_conf.h | 1 - src/conf/snapshot_conf.c | 3 +- src/libxl/libxl_driver.c | 2 +- src/qemu/qemu_domain.c | 17 +++++++--- src/qemu/qemu_domain.h | 3 +- src/qemu/qemu_driver.c | 9 ++++- src/qemu/qemu_migration_cookie.c | 2 +- src/test/test_driver.c | 2 +- src/vz/vz_driver.c | 2 +- tests/cputest.c | 15 ++++----- .../ppc64-host+guest-compat-incompatible.xml | 2 +- .../ppc64-host+guest-compat-invalid.xml | 2 +- .../cputestdata/ppc64-host+guest-compat-valid.xml | 2 +- .../qemuxml2xmlout-pseries-cpu-compat-power9.xml | 38 +++++++++++++++++++++ .../qemuxml2xmlout-pseries-cpu-compat.xml | 38 +++++++++++++++++++++ .../qemuxml2xmlout-pseries-cpu-exact.xml | 39 ++++++++++++++++++++++ tests/qemuxml2xmltest.c | 4 +++ 23 files changed, 178 insertions(+), 62 deletions(-) create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-pseries-cpu-compat-power9.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-pseries-cpu-compat.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-pseries-cpu-exact.xml
