VM Network Interface Options

StarlingX OpenStack supports a variety of standard and performance-optimized network interface drivers in addition to the standard OpenStack choices.

• Unmodified guests can use Linux networking and virtio drivers. This provides a mechanism to bring existing applications into the production environment immediately.

  Note

  The virtio devices on a VM cannot use vhost-user for enhanced performance if any of the following is true:

  • The VM is not backed by huge pages.

  • The VM is backed by 4k huge pages.

  • The VM is live-migrated from an older platform that does not support vhost-user.
