Basically qemu uses the same stream as RAM migration and libvirt takes advantage of NBD transfer. With virsh migrate-setspeed I observed that one can only control the transfer throughput of RAM, but not disk synchronization. At least this is what I can see in bmon when doing a migration with incremental copy. The question is: Am I missing something or it is not implemented? Thank you guys! </body> </html>
