Hi,
I user same base_mac configuration as previous release. It is "base_mac = 00:05:86:00:00:00".
As the comments in /etc/neutron.conf, the mac address should be fixed in first 3 octets.
# The base MAC address Neutron will use for VIFs. The first 3 octets will
# remain unchanged. If the 4th octet is not 00, it will also be used. The
# others will be randomly generated. (string value)
But in my case, it generated below mac address(9d:05:86:ba:64:a5) and failed to boot vm.
It complains "expected unicast mac address, found multicast '9d:05:86:ba:64:a5'"
Below is nova-compute log:
