All,
I've recently been playing around with migration via exec. Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened. This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time. This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.
(note: developed/tested with qemu-kvm, but applies perfectly fine to qemu)
