28.1.0 ^^^^^^
Bug Fixes
* Some OS platforms don't provide by default cpufreq resources in sysfs, so they don't have CPU scaling governors. That's why we should let the governor strategy to be optional for CPU power management.
(https://docs.openstack.org/nova/latest/admin/cpu-topologies.html #configuring-cpu-power-management-for-dedicated-cores)
* With the change from ml2/ovs DHCP agents towards OVN implementation in neutron there is no port with device_owner "network:dhcp" anymore. Instead DHCP is provided by "network:distributed" port. Fix relies on enable_dhcp provided by neutron-api if no port with "network:dhcp" owner is found. See bug 2055245 for details.
* Bug 2009280 has been fixed by no longer enabling the evmcs enlightenment in the libvirt driver. evmcs only works on Intel CPUs, and domains with that enlightenment cannot be started on AMD hosts. There is a possible future feature to enable support for generating this enlightenment only when running on Intel hosts.
