Re: [PATCH Libvirt 0/4] Support for dirty-limit live migration

In qemu>=8.1, the dirty-limit functionality for live migration was included. 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 leave the default settings in place. values as default. For more details about dirty-limit. please see the following reference: https://lore.kernel.org/qemu- devel/169024923116.19090.10825599068950039132-0(a)git.sr.ht/ Please review, thanks, Yong 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(-) -- 2.38.5
