This patch introduces a tcp protocol for live migration. It can be used as follows: qemu-system-x86_64 -hda ~/images/linux-test.img -monitor stdio <vm runs for a while> (qemu) migrate tcp:localhost:1025 On the same system: qemu-system-x86_64 -hda ~/images/linux-test.img -incoming tcp:localhost:1025 The monitor can be interacted with while waiting for an incoming live migration.
