I'm not sure how we can do faster pending write flush on block-job-complete.

Maybe implementing COLO in the future (not sure it all parts are already implemented in qemu) could help to have both disk && memory migration synced.

the relevant ones in qemu-server are already applied and packages are 
available in pve-no-subscription :) results in the forum indicate an 
improvement for shared storage migration, I will see how we can speed up 
the one with local storage a bit more as well, probably next week.
