1. Install VirtualBox. Instructions may vary from one Linux distribution to another.
2. Download Rocky Linux 9.4 ISO.
3. Create new VM in VirtualBox as you normally would do, named “cuttlefish”.
4. Specify Network Adapter 1 as NAT.





5. Specify Network Adapter 2 as internal with some name (here is default “intnet”).


6. Specify Optical Drive to insert a downloaded Rocky Linux ISO.

7. Install Rocky Linux

8. install stuff to support Vbox Guest Additions, DPDK and floweaver


sudo dnf install -y epel-release dnf-plugins-core
sudo dnf config-manager --set-enabled crb
sudo dnf install -y kernel gcc glibc-devel libbpf-devel zeromq-devel kernel-headers kernel-devel numactl-devel libibverbs-devel jansson-devel zlib-devel python-pip libpcap-devel libfdt-devel libxdp-devel libmnl-devel ninja-build git make pkgconfig cmake jq libcmocka-devel libconfig-devel

reboot if the kernel is updated, for kernel-headers and kernel version to match each other

9. Specify Optical Drive to insert a downloaded Vbox Guest Additions ISO , download it from here: https://download.virtualbox.org/virtualbox/<vbox version>/VboxGuestAdditions<some_shit>.iso


10. Install Vbox Guest Additions ISO. Refer to its documentation or ask me :)

11. Install DPDK. Steps:

pip install meson pyelftools
git clone https://dpdk.org/git/dpdk
cd dpdk
mkdir mybuild
cd mybuild
meson ..
meson compile
sudo HOME=~ $(which meson) install


12. Install floweaver’s dpdk-cuttlefish binary.

To do that, I’d suggest to add Shared Folder in VM. Mount the path to floweaver project to VM’s filespace. Let’s assume floweaver is mounted under /project folder. Then

mkdir ~/flw-build
cd ~/flw-build
sudo HOME=~ $(which meson) -Dbuildtype=release /project
sudo HOME=~ $(which meson) compile

Now you have app/dpdk-cuttlefish/dpdk-cuttlefish binary. You run it with configuration file (kindly request one from probe team).

13. Setup a client VM and assign it to the same network as “cuttlefish” VM, namely “intnet”.


You can configure it inside the guest to receive dynamic IP and if the “cuttlefish” will have running the `dpdk-cuttlefish` instance then you’ll get network connectivity through this VM.
