Hi Addala Aneesh Devasya,

NVAs are specialized workload VMs but are managed and configured through the same compute infrastructure as any Azure VM.

Encryption at Host (EaH) is implemented at the Virtual Machine level, depending on the region and the compatible VM size (SKU). This includes NVAs, as there is no separate EaH feature designed specifically for NVAs.

To enable EaH on any VM, you need to register the EncryptionAtHost feature within the Microsoft.Compute namespace for your subscription first.

Please refer the Microsoft documentation for reference: https://learn.microsoft.com/en-us/azure/virtual-machines/linux/disks-enable-host-based-encryption-cli?wt.mc_id=knowledgesearch_inproduct_azure-cxp-community-insider

Hi,

Yes, you can use Encryption at Host with NVA just like with other VMs. Inside of the NVA VM it has no awareness that you are using Encryption at Host. It reads/writes to its hard disk as usual.

The above is subject to the documented restrictions of Encryption at Host, so if one of those apply to the NVA VM then you wouldn't be able to use it, but this is true for other VMs as well.

Please click Accept Answer and upvote if the above was helpful.

Thanks.
