v3: - adjust the parameter check location for suggested by Michal - mark the VIR_MIGRATE_DIRTY_LIMIT flag since 10.0.0 - rebase on master
Thanks Michal for the comments.
Please review, Yong.
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@git.sr.ht/
