PVC according to the contentType setting. To send data to the upload proxy you must have a valid UploadToken. See the upload documentation for details.Prepare an empty Kubevirt VM diskThe special source none can be used to populate a volume with an empty Kubevirt VM disk. This source is valid only with the kubevirt contentType. CDI will create a VM disk on the PVC which uses all of the available space. See here for an example.Import from oVirtVirtual machine disks can be imported from a running oVirt installation using the imageio source. CDI will use the provided credentials to securely transfer the indicated oVirt disk image so that it can be used with kubevirt. See here for more information and examples.Content TypesCDI features specialized handling for two types of content: Kubevirt VM disk images and tar archives. The kubevirt content type indicates that the data being imported should be treated as a Kubevirt VM disk. CDI will automatically decompress and convert the file from qcow2 to raw format if needed. It will also resize the disk to use all available space. The archive content type indicates that the data is a tar archive. Compression is not yet supported for archives. CDI will extract the contents of the archive into the volume. The content type can be selected by specifying the contentType field in the DataVolume. kubevirt is the default content type. CDI only supports certain combinations of source and contentType as indicated below:http → kubevirt, archiveregistry → kubevirtpvc → Not applicable - content is clonedupload → kubevirtimageio → kubevirtDeploy itDeploying the CDI controller is straightforward. In this document the default namespace is used, but in a production setup a protected namespace that is inaccessible to regular users should be used instead.$ export VERSION=$(curl -s | grep -o "v[0-9]\.[0-9]*\.[0-9]*")$ kubectl create -f kubectl create -f itCreate a DataVolume and populate it with data from an http source$ kubectl create -f are quite a few examples in the example manifests, check them out as a reference to create DataVolumes from additional sources like registries, S3 and your local system.Hack itCDI includes a self contained development and test environment. We use Docker to build, and we provide a simple way to get a test cluster up and running on your laptop. The development tools include a version of kubectl that you can use to communicate with the cluster. A wrapper script to communicate

VM disks are transferred: The Migration Controller service creates a conversion pod with the PVCs attached to it when importing from VMWare. The conversion pod runs virt-v2v, which installs and configures device drivers on the PVCs of the target VM. The Migration Controller service creates a VirtualMachine CR for each source virtual machine (VM), connected to the PVCs. If the VM ran on the source environment, the Migration Controller powers on the VM, the KubeVirt Controller service creates a virt-launcher pod and a VirtualMachineInstance CR. The virt-launcher pod runs QEMU-KVM with the PVCs attached as VM disks. Cold migration from RHV or OpenStack to the local OpenShift cluster: When you create a Migration custom resource (CR) to run a migration plan, the Migration Controller service creates for each source VM disk a PersistentVolumeClaim CR, and an OvirtVolumePopulator when the source is RHV, or an OpenstackVolumePopulator CR when the source is OpenStack. For each VM disk: The Populator Controller service creates a temporarily persistent volume claim (PVC). If the StorageClass has a dynamic provisioner, the persistent volume (PV) is dynamically provisioned by the StorageClass provisioner. The Migration Controller service creates a dummy pod to bind all PVCs. The name of the pod contains pvcinit. The Populator Controller service creates a populator pod. The populator pod transfers the disk data to the PV. After the VM disks are transferred: The temporary PVC is deleted, and the initial PVC points to the PV with the data. The Migration Controller service creates a VirtualMachine. Deploy KubeVirt. KubeVirt can be installed using the KubeVirt operator, which manages the lifecycle of all the KubeVirt core components.

Containerized Data ImporterContainerized-Data-Importer (CDI) is a persistent storage management add-on for Kubernetes.It's primary goal is to provide a declarative way to build Virtual Machine Disks on PVCs for Kubevirt VMsCDI works with standard core Kubernetes resources and is storage device agnostic, while its primary focus is to build disk images for Kubevirt, it's also useful outside of a Kubevirt context to use for initializing your Kubernetes Volumes with data.IntroductionKubernetes extension to populate PVCs with VM disk images or other dataCDI provides the ability to populate PVCs with VM images or other data upon creation. The data can come from different sources: a URL, a container registry, another PVC (clone), or an upload from a client.DataVolumesCDI includes a CustomResourceDefinition (CRD) that provides an object of type DataVolume. The DataVolume is an abstraction on top of the standard Kubernetes PVC and can be used to automate creation and population of a PVC with data. Although you can use PVCs directly with CDI, DataVolumes are the preferred method since they offer full functionality, a stable API, and better integration with kubevirt. More details about DataVolumes can be found here.Import from URLThis method is selected when you create a DataVolume with an http source. CDI will populate the volume using a pod that will download from the given URL and handle the content according to the contentType setting (see below). It is possible to configure basic authentication using a secret and specify custom TLS certificates in a ConfigMap.Import from container registryWhen a DataVolume has a registry source CDI will populate the volume with a Container Disk downloaded from the given image URL. The only valid contentType for this source is kubevirt and the image must be a Container Disk. More details can be found here.Clone another PVCTo clone a PVC, create a DataVolume with a pvc source and specify namespace and name of the source PVC. CDI will attempt an efficient clone of the PVC using the storage backend if possible. Otherwise, the data will be transferred to the target PVC using a TLS secured connection between two pods on the cluster network. More details can be found here.Upload from a clientTo upload data to a PVC from a client machine first create a DataVolume with an upload source. CDI will prepare to receive data via an upload proxy which will transit data from an authenticated client to a pod which will populate the

Virtlet, on the other hand, is a CRI (Container Runtime Interface) implementation, which means that Kubernetes sees VMs in the same way it sees Docker containers. Virtlet is a CRI implementation, so all VMs are defined as Kubernetes Pods and treated as first-class citizens, so to speak. The advantage of this architecture is that anything you can do with Pods can be done with Virtlet VMs, right out of the box.但是virtle只支持linux平台,并且最后一次提交是2019年.而kubevirt + minikube 可以在支持嵌套虚拟化的平台上运行.安装minikubeminikube 虚拟化驱动具体介绍可以看官网文档:minikube drive可以在linux平台使用kvm逻辑安装在windows 10 平台,开启hyperv嵌套虚拟化,安装部署成一台hyperv虚拟机//开启hyperv嵌套虚拟化,进去minikube虚拟机可以看到它支持虚拟化.PS C:\WINDOWS\system32> minikube.exe ssh _ _ _ _ ( ) ( )___ ___ (_) ___ (_)| |/') _ _ | |_ __/' _ ` _ `\| |/' _ `\| || , 在macos monterey上,使用vmware fusion2 开启嵌套虚拟化,安装部署成一台虚拟化.点击下载安装minikube => minikube start | minikube (k8s.io)安装完成后, 启动集群会自动,下载相应的镜像linux在linux平��建议裸机部署, 尝试过使用kvm驱动部署, 虽然开启了嵌套虚拟化,最后, kubevirt 启动虚拟机失败.裸机安装需要先按照docker-ce, 按照官网安装如果是REHL 8 平台需要修改docker repo中[docker-ce-stable] 内容为centos .[wjh@node1 ~]$ cat /etc/yum.repos.d/docker-ce.repo |grep -ie '\[docker-ce-stable\]' -A 6[docker-ce-stable]name=Docker CE Stable - $basearchbaseurl= 考虑到不要使用root权限启动minikube, 需要给当前用户wjh,赋权执行docker 命令sudo usermod -aG docker wjh// exit 重新ssh登录账号.// 启动dockersudo systemctl start docker.servicesudo systemctl status docker.service启动minikube集群// driver none 代表裸机安装minikube start --driver=none// 查看集群状态minikube statuswindowswindows开启嵌套虚拟化管理员身份启动powershellpowershell中设置路径, 启动集群,自动下载驱动.PS C:\WINDOWS\system32> $oldPath = [Environment]::GetEnvironmentVariable('Path', [EnvironmentVariableTarget]::Machine)PS C:\WINDOWS\system32> if ($oldPath.Split(';') -inotcontains 'C:\minikube'){ `>> [Environment]::SetEnvironmentVariable('Path', $('{0};C:\minikube' -f $oldPath), [EnvironmentVariableTarget]::Machine) `>> }在windows平台使用hyperv驱动,minikube集群会被安装到hyperv的一台虚拟机上. 安装完成之后, 需要关闭集群,设置该虚拟机支持嵌套虚拟化.PS C:\WINDOWS\system32> minikube start --hyperv-virtual-switch=minikube_switch --driver=hyperv* Microsoft Windows 10 Enterprise 10.0.19044 Build 19044 上的 minikube v1.24.0 * 根据用户配置使用 hyperv 驱动程序* 正在下载 VM boot image... > minikube-v1.24.0.iso.sha256: 65 B / 65 B [-------------] 100.00% ? p/s 0s > minikube-v1.24.0.iso: 225.58 MiB / 225.58 MiB [ 100.00% 11.14 MiB p/s 20s* Starting control plane node minikube in cluster minikube* Downloading Kubernetes v1.22.3 preload ... > preloaded-images-k8s-v13-v1...: 501.73 MiB / 501.73 MiB 100.00% 11.07 Mi* Creating hyperv VM (CPUs=2, Memory=4000MB, Disk=20000MB) ...!

A list of VMs with the same migration parameters and associated network and storage mappings. Migration CR runs a migration plan. Only one Migration CR per migration plan can run at a given time. You can create multiple Migration CRs for a single Plan CR. MTV services The Inventory service performs the following actions: Connects to the source and target providers. Maintains a local inventory for mappings and plans. Stores VM configurations. Runs the Validation service if a VM configuration change is detected. The Validation service checks the suitability of a VM for migration by applying rules. The Migration Controller service orchestrates migrations. When you create a migration plan, the Migration Controller service validates the plan and adds a status label. If the plan fails validation, the plan status is Not ready and the plan cannot be used to perform a migration. If the plan passes validation, the plan status is Ready and it can be used to perform a migration. After a successful migration, the Migration Controller service changes the plan status to Completed. The Populator Controller service orchestrates disk transfers using Volume Populators. The Kubevirt Controller and Containerized Data Import (CDI) Controller services handle most technical operations. 9.3.2. High-level migration workflow The high-level workflow shows the migration process from the point of view of the user: You create a source provider, a target provider, a network mapping, and a storage mapping. You create a Plan custom resource (CR) that includes the following resources: Source provider Target provider, if

CR for each source virtual machine (VM), connected to the PVCs. If the VM ran on the source environment, the Migration Controller powers on the VM, the KubeVirt Controller service creates a virt-launcher pod and a VirtualMachineInstance CR. The virt-launcher pod runs QEMU-KVM with the PVCs attached as VM disks. Cold migration from VMWare to the local OpenShift cluster: When you create a Migration custom resource (CR) to run a migration plan, the Migration Controller service creates a DataVolume CR for each source VM disk. For each VM disk: The Containerized Data Importer (CDI) Controller service creates a blank persistent volume claim (PVC) based on the parameters specified in the DataVolume CR. If the StorageClass has a dynamic provisioner, the persistent volume (PV) is dynamically provisioned by the StorageClass provisioner. For all VM disks: The Migration Controller service creates a dummy pod to bind all PVCs. The name of the pod contains pvcinit. The Migration Controller service creates a conversion pod for all PVCs. The conversion pod runs virt-v2v, which converts the VM to the KVM hypervisor and transfers the disks' data to their corresponding PVs. After the VM disks are transferred: The Migration Controller service creates a VirtualMachine CR for each source virtual machine (VM), connected to the PVCs. If the VM ran on the source environment, the Migration Controller powers on the VM, the KubeVirt Controller service creates a virt-launcher pod and a VirtualMachineInstance CR. The virt-launcher pod runs QEMU-KVM with the PVCs attached as VM disks. 9.4.. Deploy KubeVirt.

The recommendations and solution design in this guide might also change when the software is released GA. These should be considered non-production at the time of this writing. Please contact your sales representative for details.The guide is composed of the following sections:1 INTRODUCTION2 SOLUTION DESIGN2.1 LAYER 3 OVERVIEW: REPLACING A L3 NSX TOPOLOGY WITH XC2.2 LAYER 2 OVERLAYS, PHYSICAL NETWORKS AND MICRO-SEGMENTATION 2.3 LAYER 3 DETAILED DESIGN2.4 MIGRATING SUBNET PREFIXES FROM NSX TO XC 2.5 LOAD BALANCERS AND VIPS2.6 COMPLETE NETWORK DIAGRAM USED IN THIS GUIDE 3 OVERVIEW OF THE MIGRATION PROCESS 3.1 STEP 1 - DEPLOYMENT OF XC CE SITES IN THE VMWARE DEPLOYMENT3.2 STEP 2 - VIP MIGRATION FROM THE ORIGINAL LB TO XC 3.3 STEP 3 - DEPLOYMENT OF XC CE SITES IN OPENSHIFT VIRTUALIZATION 3.4 STEP 4.

The trusted platform module (TPM) is a self-contained hardware encryption technology present in recent computer systems. It provides, among other things, hardware random number generation and more secure storage for encryption keys. This enables administrators to encrypt operating system disks that will then only be decryptable on the same system. Version 2.0 of the TPM specification was published in 2015, and Microsoft’s Windows 11 requires a version 2.0 TPM to be present to install.To support operating systems like Windows 11 that require a TPM, libvirt provides a virtual TPM (vTPM) that can be configured with a virtual machine (VM) to provide the appearance of a hardware TPM. Red Hat OpenShift Virtualization has supported vTPM as an option since Red Hat OpenShift 4.13, with the persistent storage capability added in OpenShift 4.14.This means that a Windows 11 VM can employ BitLocker encryption to its system drives and OpenShift Virtualization will handle the encryption keys on its behalf through the vTPM interface. The virtualized TPM comes with an important caveat; it does not provide the same level of security as a physical chip. Any compliance controls that rely on that physical security should be re-evaluated when considering a move to virtual.Preparing the cluster to support a persisted vTPMTo support the persistent storage of secrets in a VM’s vTPM, OpenShift Virtualization must create a Persistent Volume Claim (PVC) to back that secret storage. The storage class that provides vTPM state must be configured in the HyperConverged custom resource, typically “kubevirt-hyperconverged” in the “openshift-cnv” namespace. The storage class must be a “Filesystem” type (FS), and it should support the “ReadWriteMany” access mode (RWX) in order to allow VMs using a persistent vTPM to make use of live migration. An example of the parameter is below, taken from a cluster using Red Hat OpenShift Data Foundation:spec: vmStateStorageClass: ocs-external-storagecluster-cephfsAdding persistence to a VMThe change to the VM YAML to set the vTPM to persistent is likewise simple, if deeper in the hierarchy due to the spec.template.spec structure of a VM. The setting for TPM can be found underspec.template.spec.domain.devices.tpmTo make the vTPM use persistent storage, add “persistent: true” under “tpm”:oc patch vm win11 --type json -p '[{"op": "add", "path": "/spec/template/spec/domain/devices/tpm", "value": {"persistent": true}}]'The change to the VM may be made while it is running, but it will not take effect until it is stopped and restarted by OpenShift Virtualization. For best results, include this parameter before running
