Hi, I am trying to test picoserver app in qemu, but I am not able to connect to the echo component on port 1234. These are the steps I am following, please, let me know if I am doing something wrong. Thanks in advance: $ repo init -u https://github.com/seL4/camkes-manifest.git $ repo sync # use docker container to compile $ container @in-container:/host$ mkdir build @in-container:/host$ cd build @in-container:/host$ ../init_build.sh -DCAMKES_APP=picoserver -DPICOSERVER_IP_ADDR=127.0.0.1 -DSIMULATION=1 @in-container:/host$ ninja Everything seems to be ok, but when I tried to execute in qemu: $ sudo ./simulate --machine q35,accel=kvm,kernel-irqchip=split --mem-size 2G --extra-cpu-opts "+vmx" --extra-qemu-args="--enable-kvm -device intel-iommu,intremap=on,caching-mode=on -netdev user,id=network0,hostfwd=tcp::1234-:1234 -device e1000e,netdev=network0" It seems the echo component is listening on port 1234, but if I try to send data with "netcat 127.0.0.1 1234" I can't reach the echo component ...... IOMMU 0x0: enabling... enabled Booting all finished, dropped to user space Protocol ethernet registered (layer: 2). Protocol ipv4 registered (layer: 3). Protocol ipv6 registered (layer: 3).
