如何在现有的 Google Cloud VM 实例上启用嵌套虚拟化？

Question

I'm trying to enable Nested Virtualization on a existing VM instance. The VM is on the Intel Haswell CPU platform so Nested Virtualization is possible.

Now I've read this support article at Google: https://cloud.google.com/compute/docs/instances/enable-nested-virtualization-vm-instances

Under the first section Enabling nested virtualization on an instance it says the following:

Create a boot disk from a public image or from a custom image with an operating system. Alternatively, you can skip this step and apply the license to an existing disk from one of your VM instances.

However I can't figure out how to apply the Nested Virtualization license to an existing VM instance. The only steps described are for new disks and I want to apply it to an existing disk.

My question is: How can I enable Nested Virtualization on a existing Google Cloud Instance?

Thanks in advance, Hugo.

I will share with you instructions on how to enable Nested Virtualization on an existing GCP VM instance. More detailed steps are described in the article you shared .

1. From your existing VM instance, you should already have a boot disk in your project. If not, you should create a boot disk from that VM instance.

2. Using the boot disk from that existing VM instance, please create a custom image with the special license key required for virtualization.

   a- If you are creating an image using the gcloud command-line tool, provide the following license URL using the --licenses flag:

   https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx

   For example, the following command creates an image named nested-vm-image from an example disk named disk1 :

   $ gcloud compute images create nested-vm-image \\ --source-disk disk1 --source-disk-zone us-central1-b \\ --licenses "https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx"

   b- If you are using the API, please include the licenses property in your API request:

   POST https://www.googleapis.com/compute/v1/projects/[PROJECT_ID]/global/images { "licenses": ["projects/vm-options/global/licenses/enable-vmx"], "name": "nested-vm-image", "sourceDisk": "zones/us-central1-b/disks/disk1" }

   where [PROJECT_ID] is your project ID.
