[`blueprint Replace inner-/external computes with a dvr mode variable <https://blueprints.launchpad.net/kolla-ansible/+spec/dvr_mode_property>`_]
A new variable "neutron_compute_dvr_mode" is introduced. This variable
controls whether a compute host has external connection and is
allowed to do full-blown DVR or distributed routing is only used for
tenant networking. Corresponding values are "dvr" and "dvr_no_external"
The variable has to be set either globally or per group (per host)
to get desired behavior.
upgrade:
- |
All hosts from "[inner-compute]" and "[external-compute]" can be moved to
"[compute]" to avoid problems in OpenStack S release, though the groups
still will function well in this release.
deprecations:
- |
Splitting of compute group into inner and external compute hosts is
deprecated and will be removed in OpenStack S release.
fixes:
- |
External bridge setup on compute hosts that depends on whether DVR mode
is enabled is also accompanied by a check for the new variable.
