Create a tap device.
sudo ip tuntap add veth0 mode tap
You may need to add user $(id -u) or group $(id -g) depending on how permissions are setup on your distro.
ip tuntap add tap0 mode tap # user $(id -u) group $(id -g)tap='ftap0' br='virbr1' #Change whoami if needed, should be the user firecracker runs as #ip tuntap add dev $tap mode tap user $(whoami) #Add the TAP interface to the bridge: #brctl addbr $br ip link set $tap master $br #bring up interfaces ip link set dev $br up ip link set dev $tap up
