If you have ever had an idea to build a phyisical rasperry pi cluster like this:
http://modernhackers.com/raspberry-mini-data-center-cloud/
Much easier to build a virtual one 🙂
You have now a chance to simply simulate / build a virtual raspberry pi cluster with the help of Debian, KVM, QEMU ARM and GNS3 technologies together.
You have to prepare Debian 10.1 (Debian Buster) Virtual Machine (either under KVM or Vmware) that we use as the host machine, base image that will use for to emulate the raspberry pi and later transfer to under GNS3 (20 GB disk space is enough and created raspberry as a local user during the installer)
https://wiki.debian.org/DebianBuster
Install the necessary Binaries
apt-get install sudo git bridge-utils qemu-system-arm unzipAdd raspberry user to be part of the sudoers
raspberry ALL=(ALL) NOPASSWD: ALL4. Enable auto-login for raspberry user (otherwise you won’t be able to see furthe QEMU SYSTEM ARM console later)
systemctl edit getty@tty1Paste the following lines (all)
[Service]
ExecStart=
ExecStart=-/sbin/agetty --autologin raspberry --noclear %I 38400 linuxEnable the newly created service and reboot
systemctl enable getty@tty1.service
rebootYou have to fine tune the Debian OS for being able to run the QEMU ARM binary and have network support as well.
-Under Vmware ens33, before KVM (GNS) export, you have to re-name to ens3, otherwise under KVM the network won’t come up automatically
-You have to create a br0 bridge interface and to add both ens3 and tap0 interfaces, latter will be used by the emulated QEMU System ARM daemon to connect the raspberry interface to the bridge
root@debian:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug ens3
iface ens3 inet manual
auto br0
iface br0 inet dhcp
pre-up ip tuntap add dev tap0 mode tap user root
pre-up ip link set tap0 up
bridge_ports all ens3 tap0
bridge_stp off
bridge_maxwait 0
bridge_fd 0
post-down ip link set tap0 down
post-down ip tuntap del dev tap0 mode tapNavigate to under the service user (raspberry) /home/raspberry
cd /home/raspberryYou will need to have a modified kernel to run raspberry as virtual
git clone https://github.com/dhruvvyas90/qemu-rpi-kernel.gitWe will select the best/most compatible kernel:
ln -s /home/reaspberry/qemu-rpi-kernel/kernel-qemu-4.4.34-jessie kernelDownloan a Raspbian headless factory image that compatible with the downloaded kernels, I have tested and raspbian buster does working with jessie kernel:
wget http://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2019-09-30/2019-09-26-raspbian-buster-lite.zipUnzip the Image
unzip ./raspbian_lite-2019-09-30/2019-09-26-raspbian-buster-lite.zipConvert to QCOW2
qemu-img convert -f raw -O qcow2 raspbian_lite-2019-09-30/2019-09-26-raspbian-buster-lite.img raspbian-buster-lite.qcowExtend the disk size
qemu-img resize raspbian-buster-lite.qcow +6GCreate a symlink for the image for easier administration
ln -s raspbian-buster-lite.qcow imageAdd QEMU ARM to the auto start, add the following section to the /home/raspberry/.profile file
We need to Generate Unique mac address for each individual qemu-system-arm instances, otherwise the local router returns the same IP for each nodes
MACADDR="52:54:00:$(dd if=/dev/urandom bs=512 count=1 2>/dev/null | md5sum | sed 's/^\(..\)\(..\)\(..\).*$/\1:\2:\3/')";Then we can incorporate the $MACADDR variable to the qem-usystem-arm init command
sudo qemu-system-arm -kernel /home/raspberry/kernel -append "root=/dev/sda2 console=ttyAMA0 panic=1 rootfstype=ext4 rw" -hda /home/raspberry/image -cpu arm1176 -m 256 -M versatilepb -no-reboot -nographic -net nic,macaddr=$MACADDR -net tap,ifname=tap0Create a QEMU template in GNS3 and attach the creade .vmdk image file
First boot
sudo qemu-system-arm -kernel kernel -append "root=/dev/sda2 console=ttyAMA0 panic=1 rootfstype=ext4 rw" -hda image -cpu arm1176 -m 256 -M versatilepb -no-reboot -nographic -net nic,macaddr=$MACADDR -net tap,ifname=tap0
