Create a VM Pool

Deploy a VM pool

A VM pool is a set of pre-provisioned KubeVirt VMs. Idle VMs are allocated on SSH connection, destroyed on disconnect, and automatically replaced to maintain replica count.

Deploy

kubectl apply -f https://github.com/Azure/blip/releases/latest/download/pool.yaml

Pin a version by replacing latest/download with e.g. download/v0.1.0.

Kustomize

Base image

The root disk is served as a containerDisk — a regular container image containing the VM filesystem. No PVCs or CDI are required.

volumes:
  - containerDisk:
      image: quay.io/containerdisks/fedora:40
    name: rootdisk

The image must be cloud-init-compatible with sshd installed.
