Description
What problem are you trying to solve?
https://aws.amazon.com/about-aws/whats-new/2026/02/amazon-ec2-nested-virtualization-on-virtual/
We'd like Karpenter to be able to request EC2 instances with Nested Virtualization enabled.
I believe this is configured through CpuOptions, which #8844 aims to support... at least for coreCount and threadsPerCore.
The feature would require an additional option in CpuOptions for NestedVirtualization=enabled|disabled.
How important is this feature to you?
This will be important for many. It has been a long time coming for AWS to support nested virtualization on virtual EC2 instances. Nested virtualization was only possible on bare metal EC2 instances before ($$$).
