Some cleanup operations take long time during the pause and copy stage,
especially with the KVM patch 3ea3b7fa9af067, do these operations after
the completion of live migration can help to reduce VM downtime.
Ony the first patch changes the behavior, the rest 3 patches are for code
cleanup.
Hi Paolo Marcelo,
Could please point out what issue the patch 317b0a6d8ba44e try to fix? I
found in live migration the cpu_synchronize_all_states will be called twice,
and it will take more than 1 ms sometimes. I try to do some optimization but
lack the knowledge about the background.
