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
