v2: - mark the VIR_MIGRATE_DIRTY_LIMIT flag since 9.10.0 v1: The dirty-limit functionality for live migration was introduced since qemu>=8.1. In the live migration scenario, it implements the force convergence using the dirty-limit approach, which results in better reliable read performance. A straightforward dirty-limit capability for live migration is added by this patchset. Users might not care about other dirty-limit arguments like "x-vcpu-dirty-limit-period" or "vcpu-dirty-limit," thus do not expose them to Libvirt and Keep the default configurations and values in place. For more details about dirty-limit, please see the following reference: https://lore.kernel.org/qemu- devel/169024923116.19090.10825599068950039132-0@xxxxxxxxx/ Hyman Huang (4): Add VIR_MIGRATE_DIRTY_LIMIT flag qemu_migration: Implement VIR_MIGRATE_DIRTY_LIMIT flag virsh: Add support for VIR_MIGRATE_DIRTY_LIMIT flag NEWS: document support for dirty-limit live migration NEWS.rst | 8 ++++++++ docs/manpages/virsh.rst | 10 +++++++++- include/libvirt/libvirt-domain.h | 5 +++++ src/libvirt-domain.c | 8 ++++++++ src/qemu/qemu_migration.c | 8 ++++++++ src/qemu/qemu_migration.h | 1 + src/qemu/qemu_migration_params.c | 6 ++++++ src/qemu/qemu_migration_params.h | 1 + tools/virsh-domain.c | 10 ++++++++++ 9 files changed, 56 insertions(+), 1 deletion(-) -- 2.39.1 _______________________________________________ Devel mailing list -- devel@xxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxx
