I've been racking my brain trying to work out if this is possible. I would like to be able to forward to a guest TCP port, via a host UNIX socket to avoid opening a TCP port on the host. For example: qemu-system-i386 [...] -nic user,hostfwd=3Dunix:/path/to/socket-:22 and then connect to the VM like: ssh -o "ProxyCommand socat - unix-connect:/path/to/socket" user@0.0.0.0 QEMU, as versatile as it is, doesn't appreciate my intuited syntax "hostfwd=3Dunix:...". It is also unhappy with: qemu-system-i386 [...] \ -chardev socket,id=3Dfoo,path=3D/path/to/socket,server,nowait \ -nic user,hostfwd=3Dchardev:foo-:22 And: qemu-system-i386 [...] \ -nic user \ -chardev socket,id=3Dfoo,path=3D/path/to/socket,server,nowait \ -chardev socket,id=3Dfoo,host=3D10.0.2.15,port=3D22 I already found out how to connect in the opposite direction, **from** guest TCP to host UNIX, via guestfwd -> cmd -> socat. So I feel like there ought to be a way. If this is not yet a feature I would like to request it, and if it is, please tell me how! ** Affects: qemu Importance: Undecided Status: New ** Tags: feature-request -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1887604 Title: Forward host UNIX socket to guest TCP port Status in QEMU: New Bug description: Hello.
