[Bug 1692028] [NEW] duplicate mac address during config-drive configuration with LXD container on openstack

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Whilst testing the changes for nova-lxd to resolve issues with use of
config-drive, I tripped over this issue; specifically the networking on
a config-drive configured LXD instance never starts due to a duplicate
MAC address on the lo and greptap0 devices.
