KubeVirt

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

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}
