Getting Started with VM Runtime

In this part, you will know how to use kubectl to create a VM using a public image and default credentials. You will also know how to connect to the VM after it is created and delete it when you no longer need it.

Create a VM.

Create a VM in the cluster. The virtctl add-on is used together with the kubectl command. Run the following command to create a VM that uses the CirrOS image. By default, the VM uses the default storage class and has two vCPUs, 4-GiB memory, and a 20-GiB boot disk in ReadWriteOnce mode.
```
virtctl create vm --name VM_NAME --volume-containerdisk src:quay.io/kubevirt/cirros-container-disk-demo:latest --memory "4Gi" | kubectl create -f -
```
Configure VM_NAME as follows:
- VM_NAME: Enter up to 63 characters. Start and end with a lowercase letter or digit. Only lowercase letters, digits, and hyphens (-) are allowed.
  The following is an example:
  1. Create a VM named testvm.
```
virtctl create vm --name testvm --volume-containerdisk src:quay.io/kubevirt/cirros-container-disk-demo:latest --memory "4Gi" | kubectl create -f –
```
  2. Wait for a while and run the following command to check the VM status:
```
kubectl get vm
```
    The following example output shows that the VM is in the Running state:
```
NAME     AGE   STATUS    READY
testvm   54s   Running   True
```
Connect to the VM.

Access the VM console when the VM is running.
1. To access a VM through the console, run the following virtctl command:
```
virtctl console testvm
```
  You will see the following information:
```
Successfully connected to testvm console. The escape sequence is ^]
```
2. Press Enter. The following information is displayed:
```
login as 'cirros' user. default password: 'gocubsgo'. use 'sudo' for root.
login:
```
3. Enter the username and password, for example, cirros and gocubsgo.
  After the VM console is successfully connected, exit the VM session and console.
```
Ctrl + ]
```
Delete the VM and its associated DataVolume.
```
 kubectl delete vm testvm
```
