Watch this:
$ qemu-system-x86_64 -S -display none -qmp stdio -accel kvm,dirty-ring-size=1024
{"QMP": {"version": {"qemu": {"micro": 90, "minor": 2, "major": 7}, "package": "v8.0.0-rc0-15-g918ee397b6-dirty"}, "capabilities": ["oob"]}}
{"execute": "qmp_capabilities"}
{"return": {}}
{"execute": "set-vcpu-dirty-limit","arguments": {"dirty-rate": 200}
Hangs.
If I'm using it incorrectly (I have no idea), it should fail, not hang.

Indeed, it seems that the command syntax is right.
Would you please get the Qemu backtrace when it hang?
I'll reproduce it and update the process in the coming days.
Thanks for posting this issue.

No, it isn't, the closing brace is missing. Ignore me while I look for
a place to hide!
