Running the Nanos Unikernel Inside Firecracker

by As for isolation levels you are going to have about the same isolation as you would get with KVM - it uses the same facilities underneath.

If you wish to run the unikernel in firecracker you can use this vm_config.json template below.

You can setup the dhcp server with this config like so: (Found in /etc/dhcp/dhcpd.conf): Create a tap device for your dhcp server to listen in on: Run it against your tap device.

You should see some ARP requests fly by once firecracker boots: Once you boot your unikernel you should also see it grab an ip: I've found it easier to play with firecracker by breaking up the one large default vm_config.json into multiple commands each with different configs.
