Nested Virtualization Enabling

xxvii27 · 02-03-2022 12:47 PM

Hello,

I am trying to enable nested virtualization on one of my existing VM.

I followed the docs https://cloud.google.com/compute/docs/instances/nested-virtualization/enabling

and verified the instance information is updated

"advancedMachineFeatures": { "enableNestedVirtualization": true }, "canIpForward": false,

However grep -cw vmx /proc/cpuinfo still yields 0?

any insights?

Hello,
Before you enabled the nested virtualization directly on an existing VM, did you check whether nested virtualization is allowed for your organization, or project?

Do you try to reboot your VM after enabled nested virtualization?

@xxvii27. To enable nested virtualization on VM instances, you'll need to achieve a few requirements. First, construct a custom image that supports nested virtualization and a VM instance based on it.
Syntax:

gcloud compute images create image-name \
--source-image-family=debian-10 \
--source-image-project=debian-cloud \
--licenses=https://compute.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx
