[rdo] [packstack] failing to setup Stein with Openvswitch/VXLAN networking


Hmmmmm. I just succeeded in setting up my Packstack after removing IPv6 
from the kernel and cleaning out ifgcfg-eth0. Since I don't need IPv6, I 
am good. My config:

$ *cat /etc/sysconfig/network-scripts/ifcfg-eth0*
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=192.168.1.202
PREFIX=24
GATEWAY=192.168.1.1
DNS1=192.168.1.16
DNS2=1.1.1.1
DOMAIN=home
IPV6INIT=no
$ *cat /etc/sysctl.conf*
net.ipv6.conf.eth0.disable_ipv6=1

Thanks again, Alfredo.
