Thanks for the response. I'm not sure, how would I run qemu with a fd= socketpair on the command line?
The wiki (https://wiki.qemu.org/index.php/Documentation/Networking) suggests for example to use: -netdev socket,id=mynet0,listen=:1234 -netdev socket,id=mynet0,connect=:1234 This would allow however anyone on the same network (or in the world if run on a server) to connect to this network and possibly do bad things. Using localhost binding helps but is still risky if there is more than one user on a given machine. Using something like: -netdev socket,id=mynet0,listen=~/.qemu-netsocket -netdev socket,id=mynet0,connect=~/.qemu-netsocket How would one do that with fd= ? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1903470 Title: qemu 5.1.0: Add UNIX socket support for netdev socket Status in QEMU: Incomplete Bug description: Note: this is a feature request. qemu has a way to connect instances using a socket: -netdev socket,id=str[,fd=h][,listen=[host]:port][,connect=host:port] This can also be used to connect a qemu instance to something else using a socket connection, however there is no authentication or security to the connection, so rather than using a port which can be accessed by any user on the machine, having the ability to use or connect to UNIX sockets would be helpful, and adding this option should be fairly trivial. UNIX sockets can be found in various parts of qemu (monitor, etc) so I believe having this on network would make sense.
