Subject: libxc sr number of iterations
|
|
|
|
Reduce default value of --max_iters from 5 to 1.
|
|
The workload within domU will continue to produce dirty pages.
|
|
It is unreasonable to expect any slowdown during migration.
|
|
Now there is one initial copy of all memory, one instead of five
|
|
iterations for dirty memory, and a final copy iteration prior move.
