KubeVirt lets you setup and manage virtual machines on your kubernetes cluster.

Getting Started

Background

KubeVirt creates two new types of resources on your cluster: VirtualMachine (vm) and VirtualMachineInstance (vmi). VirtualMachine defines how to create VMIs. VirtualMachineInstance represent a running virtual machine.

Similar to deployments-pods, you will typically not create VirtualMachineInstance manually. Instead you define VirtualMachine in your manifests and control them using virtctl. Then KubeVirt will automatically create VirtualMachineInstance.

Requirements

See requirements

  • You need a kubernetes cluster with kubectl set up.
  • You do not need to install qemu-kvm libvirt-daemon-system on the nodes.

Install KubeVirt

See installation

Install commands
# Get the latest version string
export VERSION=$(curl -s https://api.github.com/repos/kubevirt/kubevirt/releases | grep tag_name | grep -v -- '-rc' | sort -r | head -1 | awk -F': ' '{print $2}' | sed 's/,//' | xargs)
echo $VERSION

# Deploy operator
kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-operator.yaml
# Deploy custom resources
kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-cr.yaml

# Install virtctl
VERSION=$(kubectl get kubevirt.kubevirt.io/kubevirt -n kubevirt -o=jsonpath="{.status.observedKubeVirtVersion}")
ARCH=$(uname -s | tr A-Z a-z)-$(uname -m | sed 's/x86_64/amd64/') || windows-amd64.exe
echo ${ARCH}
curl -L -o virtctl https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/virtctl-${VERSION}-${ARCH}
chmod +x virtctl
sudo install virtctl /usr/local/bin
