As I mentioned when you asked in the IRC channel, you shouldn't be using fd= here when starting kvm by hand -- it expects to be passed an open file descriptor to a tap device (on fd 17, in your examples), and since you almost certainly _don't_ have such a file descriptor in your shell, you're setting things up for failure; in prior versions (and maybe the current one as well), this resulted in endless looping on a select() call returning EBADF.
