here is a sample manifest for a vm having persistent storage for both the image and additional volumes

apiVersion: vm.rancher.io/v1alpha1 kind: VirtualMachine metadata: annotations: name: testvm2 spec: action: start cpus: 2 hosted_novnc: true image: rancher/vm-rancheros:0.3.0 image_pvc: image image_vmtools: "" kvm_extra_args: "" memory_mb: 4096 node_name: "" public_keys:

• jerome use_hugepages: false volumes_pvc: volumes

when deleting the VM and re-creating it, forcing it to be run on another node, I can get what was written to the virtual disk before deleting the VM
