migration was included. In the live migration<br>
scenario, it implements the force convergence<br>
using the dirty-limit approach, which results in<br>
better reliable read performance. A straightforward<br>
dirty-limit capability for live migration is added by<br>
this patchset. Users might not care about other<br>
dirty-limit arguments like "x-vcpu-dirty-limit-period"<br>
or "vcpu-dirty-limit," thus do not expose them to<br>
Libvirt and leave the default settings in place.<br>
values as default. For more details about dirty-limit.<br>
