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.
