In Kolla Ansible OpenStack deployments, by default, libvirt is
configured to allow read-write access via an unauthenticated,
unencrypted TCP connection, using the internal API network. This is to
facilitate migration between hosts.
By default, Kolla Ansible does not use encryption for services on the
internal network (and did not support it until Ussuri). However, most
other services on the internal network are at least authenticated
(usually via passwords), ensuring that they cannot be used by anyone
with access to the network, unless they have credentials.
The main issue here is the lack of authentication. Any client with
access to the internal network is able to connect to the libvirt TCP
port and make arbitrary changes to the hypervisor. This could include
starting a VM, modifying an existing VM, etc. Given the flexibility of
the domain options, it could be seen as equivalent to having root access
to the hypervisor.
Kolla Ansible supports libvirt TLS [1] since the Train release, using
client and server certificates for mutual authentication and encryption.
However, this feature is not enabled by default, and requires
certificates to be generated for each compute host.
This change adds support for libvirt SASL authentication, and enables it
by default. This provides base level of security. Deployments requiring
further security should use libvirt TLS.
