I think the monitor interface could use improvement. I think it would look better as:(qemu) receivefd /path/to/unix/socket /* waits until it receives an fd on /path/to/unix/socket */ fd=10 (qemu) closefd 10 Then all of the existing uses of fd= can be preserved.
Ouch, my fd tags are much better as they don't require the user to read the fd number.
I like the idea of using a temporary socket because you don't have to rely on the monitor being on a unix socket. This will be especially useful when we can support tunneling the monitor through VNC.
I can't really see a user creating an fd and passing it to qemu through a unix domain socket. This is for management apps.
-- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain.
