11.6. Launching an instance with memory encryption

To verify that you can launch instances on an AMD SEV Compute node with memory encryption enabled, use a memory encryption flavor or image to create an instance.


  1. Create an instance by using an AMD SEV flavor or image. The following example creates an instance by using the flavor created in Creating a flavor for memory encryption and the image created in Creating an image for memory encryption:

    (overcloud)$ openstack server create --flavor m1.small-amd-sev \
     --image amd-sev-image amd-sev-instance
  2. Log in to the instance as a cloud user.
  3. To verify that the instance uses memory encryption, enter the following command from the instance:

    $ dmesg | grep -i sev
