We can see the '"status": "postmigrate"' object somewhere below, so it seems to me like the silent=yes part for the query-migrate execution didn’t work as intended.(And it does seem to work below, when waiting for a “100 %” to appear on $dest.)It’s been a while since we’ve touched common.qemu, so nothing comes to my mind immediately that might have broken this.

I’ve never hit this so far.The only things to try I can come up with would be to bisect, or to try adding `silent=$silent` to the `_timed_wait_for` calls in `send_qemu_cmd`...
Seems also like it does not reproduce that easily, though - I've just seen it once so far while running "make -j6 check SPEED=slow", so lots of other stuff was happening at the same time. I'll keep an eye on it to see whether I can reproduce it more easily somehow.
