I am running devstack-gate: http://paste.openstack.org/show/197749/
It's a default install for Fedora 21 (ppc64), precached with
prepare_node.sh script.
Looks like NetworkManager keeps adding routes for dhcp interfaces like:
default via 9.114.112.254 dev eth0 proto static metric 1024
I do not make any changes to the network, it's basically the same code I
had for f20 images.
I am trying to replace NetworkManager with legacy network to see if the
issue disappears.
If any other suggestions, please let me know.
Thanks.
