KubeVirt Demo

This demo will deploy KubeVirt on an existing minikube with Kubernetes 1.9 or later.

Quickstart

Deploy KubeVirt

This demo assumes that minikube is up and running and kubectl available on your system. If not, then please take a look at the guide below

With minikube running, you can easily deploy KubeVirt:

$ export VERSION=v0.3.0
$ kubectl create \
    -f https://github.com/kubevirt/kubevirt/releases/download/$VERSION/kubevirt.yaml

Note: The initial deployment to a new minikube instance can take a long time, because a number of containers have to be pulled from the internet. Use watch kubectl get --all-namespaces pods to monitor the progress.

Deploy a VirtualMachine

Once you deployed KubeVirt you are ready to launch a VM:

# Creating a virtual machine
$ kubectl apply -f https://raw.githubusercontent.com/kubevirt/demo/master/manifests/vm.yaml

# After deployment you can manage VMs using the usual verbs:
$ kubectl get ovms
$ kubectl get ovms -o yaml testvm

# To start an offline VM you can use
$ kubectl patch offlinevirtualmachine testvm --type merge -p '{"spec":{"running":true}}'
$ kubectl get vms
$ kubectl get vms -o yaml testvm

# To shut it down again
$ kubectl patch offlinevirtualmachine testvm --type merge -p '{"spec":{"running":false}}'

# To delete: kubectl delete vms testvm
# To create your own: kubectl create -f $YOUR_VM_SPEC

Accessing VMs (serial console & spice)

Note: This requires kubectl from Kubernetes 1.9 or later on the client

A separate binary is provided to get quick access to the serial and graphical ports of a VM. The tool is called virtctl and can be retrieved from the release page of KubeVirt:

$ curl -L -o virtctl \
    https://github.com/kubevirt/kubevirt/releases/download/$VERSION/virtctl-$VERSION-linux-amd64
$ chmod +x virtctl

Now you are ready to connect to the VMs:

# Connect to the serial console
$ ./virtctl console --kubeconfig ~/.kube/config testvm

# Connect to the graphical display
$ ./virtctl vnc --kubeconfig ~/.kube/config testvm

User Guide

Now that KubeVirt is up an running, you can take a look at the user guide to understand how you can create and manage your own virtual machines.

Appendix: Deploying minikube

If not installed, install minikube as described here
1. Install the kvm2 driver
2. Download the minikube binary
Launch minikube with CNI:

$ minikube start \
  --vm-driver kvm2 \
  --network-plugin cni

Install kubectl via a package manager or download it
