247  * It's tricky to use qemu's migration event capability with qtest,

472  * Our goal is to ensure that we run a single full migration
476  * We can't directly synchronize with the start of a migration
480  * Initially we set the migration bandwidth to an insanely
482  * guarantees migration will never complete.
485  * so we can't let the entire migration pass run at this speed.
490  * Before migration starts, we write a 64-bit magic marker
502  * IOW, we're guaranteed at least a 2nd migration pass
