The issue is in os/src/drivers/nic/linux/main.cc:84 Genode::strncpy(ifr.ifr_name, "tap0", sizeof(ifr.ifr_name)); This means any instance of the base-linux nic_drv tries to configure its tap device with name "tap0" which is denied by the Linux kernel. We could add an optional config option for the tap-device name to support scenarios with several instances of nic_drv on Linux.
