Add --vsock option for guest-to-host Unix socket IPC - #88
Merged
Conversation
Allow mapping guest AF_VSOCK ports to Unix sockets on the host via
libkrun's krun_add_vsock_port(). A guest connection to (CID 2, PORT)
is proxied to the host socket at PATH, so host services can be reached
without giving the guest any network access. The flag can be repeated
to map multiple ports:
krunvm start myvm --vsock 8765:/run/bridge.sock -- ...
Only wired into 'krunvm start' for now; the mapping is per-invocation
and intentionally not persisted in the VM config.
