Setting up VXLAN between nested virt VMs on Google Compute Engine
I wanted to play with a VXLAN mesh between VMs on more than one hypervisor node, but the setup for VXLAN ended up being a separate post because it was a bit long. Read that post first if you want to follow the instructions here. Now that we have a working VXLAN mesh between our two nodes we can move on to installing libvirt (which is called libvirt-daemon-system on Debian, not libvirt-bin as on Ubuntu): sudo apt-get install -y qemu-kvm libvirt-daemon-system sudo virsh net-start default sudo virsh net-autostart --network default I'm going to use a little python helper to launch my VMs, so I need some other dependancies as well: sudo apt-get install -y python3-pip pkg-config libvirt-dev git git clone https://github.com/mikalstill/shakenfist cd shakenfist git checkout 6bfac153d249752b27d224ad9d079095b640498e sudo mkdir /srv/shakenfist sudo cp template.debian.xml /srv/shakenfist/template.xml sudo pip3 install -r requirements.txt Let's launch a quick test VM to make sure the helper works: sudo python3 daemon.py sudo virsh list You can destroy that VM for now, it was just testing the install. sudo virsh destroy ...name... Next we need to tweak the template that shakenfist is using to start instances so that it uses the bridge for networking (that template is the one…
