Re: [libvirt-users] Retrieving datas sent by host within the Guest

Hi, I' trying to read datas sent by my KVM host within the Guest. Host send these datas trough a channel UNIX type , by using AF_UNIX socket stuff. If i try to retrive the datas by using such type of thing in the Guest : #define NAME "/dev/virtio-ports/agent" sock = socket(AF_UNIX, SOCK_STREAM, 0); 12 if (sock < 0) { 13 perror("opening stream socket"); 14 exit(1); 15 } 16 server.sun_family = AF_UNIX; 17 strcpy(server.sun_path, NAME); 18 if (bind(sock, (struct sockaddr *) &server, sizeof(struct sockaddr_un))) { 19 perror("binding stream socket"); 20 exit(1); 21 } I got ""binding stream socket Address already in use" when trying to bind the socket .

But If I use such kind of thing : fd = open("/dev/virtio-ports/agent", O_RDWR | O_NONBLOCK); ssize_t size = read(fd, &rcv_buffer, 100); if(size >0) printf("Read length(%d) %s\n", size, rcv_buffer); It works fine. Is there any chance to be able to use socket stuff on Guest side or is there anything I misunderstand? Thanks for help. J.P. J.P. Ribeauville P: +33.(0).1.47.17.20.49 .
