testnetz

easy autoinstaller for os tests using libvirt, docker and openvswitch

• it builds a virtual network using openvswitch

• runs virtaual machines inside kvm using libvirt

• and virtaual containers using docker

• all systems starts with unattended autoinstaller controled by .json files

• you can also install baremetal-systems using PXE

!!! Warning !!!

this scripts copy files and maybe overwrites files in:

• /var/www/html (./hosts ./install.conf ./openbsd-6.6 -- for post-install scripts and the openbsd-autoinstaller)

• /var/lib/tftpboot (./pxelinux.0 ./pxelinux.cfg/default and many more)

• /etc/dnsmasq.conf (overwrite by init-ovs.sh)

and setup some network devices:

• openvswitch (by init-ovs.sh)

• iface virbr0 will be deactivate (by init-ovs.sh)

• /proc/sys/net/ipv4/ip_forward set to 1 (by init-ovs.sh)

• ovs-vsctl add-br ovsbr and set IP (by init-ovs.sh)

• ovs-vsctl add-br ovsbr2 and set IP (by init-ovs.sh)

TODO's

• windows: missing fix-links to download WinPE iso and some tools

• freebsd: autoinstaller via PXE (at the moment, only ISO-Autoinstaller works)

• netbsd: autoinstaller (there are no official autoinstaller exist)

• osx: autoinstaller (no install will work)

• all OS's: add more predifined service installer

Quickstart

install virt-manager, libvirt, tftp-server, dhcp-server, dnsmasq and webserver

apt-get install qemu virt-manager python3-pip openvswitch-switch atftp isc-dhcp-server apache2 docker.io qemu-kvm net-tools websockify

pip3 install blowfish

pip3 install isoparser

pip3 install whiptail

for PXE-Boot you need to setup your dhcp-server:

• example-file: doc/dhcpd.conf

starting web-frontend (only for overview - http://127.0.0.1:8082)

./testnetz.py

check and run ovs init-script:

vi init-ovs.sh sh init-ovs.sh

start ubuntu installation inside kvm using libvirt and Install-ISO (first start take a while, downloading the Ubuntu-ISO)

./init.py -f hosts/ubuntu1910-libvirt.json

prepare pxe boot: (this take a while, downloading some boot-images and kernels for PXE / ~900MB)

./init.py -p

start centos installation inside kvm using libvirt and PXE-Boot

./init.py -f hosts/centos8-pxe.json

start debian installation inside docker

./init.py -f hosts/debian10-docker.json
