VM Sockets (vsock) is a communication mechanism between guest virtual machines and the host.

This tool makes it possible to use vsock for guest to guest communication.

It listens for incoming connections on host, connects to the guest virtual machine and forwards data in both directions.

Initialize the build:

meson setup build
cd build

Build the executable:

meson compile

vsockproxy <local_port> <remote_cid> <remote_port>

local_port - port number on host where to listen for incoming connections from guest virtual machines

remote_cid - CID of the vsock in the guest virtual machine where the data will be forwarded

remote_port - port number of the vsock in the guest virtual machine where the data will be forwarded
