(Conditional) Step B: Enable CPU Passthrough - AWS Elemental Server

This is version 2.15 of the AWS Elemental Server documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Conductor File and AWS Elemental Server Documentation.

(Conditional) Step B: Enable CPU Passthrough

Perform this step if you have AWS Elemental Server deployed on a kernel-based virtual machine (KVM). Otherwise, skip to Step C: Upgrade the Node.

Enable CPU passthrough so that the KVM can tell what CPU you're using. The AWS Elemental software installer could fail, or jobs remain in a pending state, if passthrough isn't enabled.

To enable CPU passthrough

  1. At the Linux command line on the KVM host, use the following command to update the virtual machine configuration file.

    sudo virsh edit hostname

    where hostname is the name that you gave the virtual machine when you deployed it.

  2. Go to the line that defines cpu mode and change it to host-passthrough.

  3. Save and exit the editor.

  4. Enable passthrough on all KVMs that you deployed.
