I find there are four kinds of uri for qmp_migrate
"tcp:", "exec:", "unix:", and "fd:"

now I want to migrate the vm to a local file with "exec:" uri by hmp-command.

How should I do the migration?

(qemu) migrate -d exec:cat>/tmp/vm.out

.... -incoming fd:</tmp/vm.out

thank you. it can work now.
there are still some questions.
1. the migration file vm.out is a QEMU suspend to disk image.
How can I reboot vm.out by QEMU?

2. I execute "migrate" with -b option, seems that the "migrate" runs at background.
I cat get the "migrate" information by qmp , there is a { "execute": "query-migrate" } command in qmp-command.
But I can not get the the "migrate" information by hmp, there is not a "query-migrate" command in hmp-command.
