Live migration




Specifies the name of the NIC device on the actual host that will be used by Nova for the live migration of instances.

Mirantis recommends setting up your Kubernetes hosts in such a way that networking is configured identically on all of them, and names of the interfaces serving the same purpose or plugged into the same network are consistent across all physical nodes.

Also, set the option to vhost0 in the following cases:

  • The Neutron service uses Tungsten Fabric.

  • Nova migrates instances through the interface specified by the Neutron’s tunnel_interface parameter.
