Re: Rebooted, now can't ping my guest
Hi Aaron and The King in Yellow,
I also experienced this problem yesterday and I just solved.
Besides ensuring quantum-openvswitch-agent processes are all up
(except the controller node),
there is a typo in the network node in basic install doc:
http://docs.openstack.org/folsom/basic-install/content/basic-install_network.html
DO NOT SET GATEWAY as 192.168.0.254.
or the routing table would be messed up.
Also, if you want to do ssh, based on the following doc:
https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/stable/GRE/OpenStack_Folsom_Install_Guide_WebVersion.rst
REMEMBER TO DO THE FOLLOWING IN YOUR CONTROLLER NODE:
route add -net 10.10.10.0/24 gw $router_proj_one_IP
Sincerely,
Hsiao
