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.
With command line switches, you have to know when starting the VM that
it is going to accept an incoming migration. Would it be possible to
change this so that the incoming migration could be triggered from
monitor? For example to migrate back to original host?
Yup. The main reason for an -incoming flag is it makes the ssh:
protocol easier to implement (not included here).
I'll add a monitor command too.
