Re: [Qemu-devel] QEMU live block-migration

Yes, I found it in the qemu-1.5.1 and it's much clear for me now. I think I need to work on this version, other than the out-of-date version qemu-kvm-1.2.0. Thanks a lot.

I used the qemu-kvm 1.2.0, so I did not find it in the code. I will move to the current qemu version. Thanks!

Yup

What version of QEMU are you looking at? For current releases you should see
the following in migrate_fd_connect():

    qemu_thread_create(&s->thread, migration_thread, s,
                       QEMU_THREAD_JOINABLE);
