Hi, I have the need to communicate efficiently between Windows 7 host and linux guest. I tried first to use an IP socket communication using TAP driver on Windows. Unfortunately, we reach a maximum of 4 Mbits/s where I would need faster communication (more than 10 Mb/s). I don’t know yet if the TAP driver is slow.
Anyway, I wonder if there are other way to do such communication. In the qemu reference help, I can see that there are some options to communicate through a pipe for example: -chardev backend ,id=id [,mux=on|off] [,options] Backend is one of: null, socket, udp, msmouse, vc, ringbuf, file, pipe, console, serial, pty, stdio, braille, tty, parallel, parport, spicevmc. spiceport. The specific backend will determine the applicable options. But I don’t really understand what this exactly does and I never managed to use it. Is it supposed to map some hardware read/write on read/write on pipe? What kind of hardware? How to use it? Do I need modifications on the Linux guest? Thanks a lot for your help, sgripon
