we tried of working on socket and pipes, In the original hardware, We have 2 compute modules. A serail interface is available between them and we run a SLIP protocol in software for the communication.
We would like to replecate the same in Qemu environment. In our scenario the machine A and a machine B both runs the same software image, they both should communicate over a SLIP protocol. We tried using pipes but we are not sure how to communicate between 2 Virtual machines using them. We appreciate a solution to communicate between Machine A and B using pipe or by establishing a SLIP protocol between the machines. Is there any way to establish a pipe between master and slave machine ?
