Thanks Michal for the comments.

Please review,

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
