2013-12-16 03:08:19 -0600 asked a question VM Can Ping Internet With No Floating IP

Hi all, this strange condition that i have, vm can ping internet once i set gateway in router. Gateway here is my local IP that can be used for internet. I figured it out that VM get router IP.

Here's the iptables on router (neutron) before and after set gateway out.

Before:

-A PREROUTING -j neutron-l3-agent-PREROUTING
-A OUTPUT -j neutron-l3-agent-OUTPUT
-A POSTROUTING -j neutron-l3-agent-POSTROUTING
-A POSTROUTING -j neutron-postrouting-bottom
-A neutron-l3-agent-PREROUTING -d 169.254.169.254/32 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9696
-A neutron-l3-agent-snat -j neutron-l3-agent-float-snat
-A neutron-postrouting-bottom -j neutron-l3-agent-snat

After:

-A PREROUTING -j neutron-l3-agent-PREROUTING
-A OUTPUT -j neutron-l3-agent-OUTPUT
-A POSTROUTING -j neutron-l3-agent-POSTROUTING
-A POSTROUTING -j neutron-postrouting-bottom
-A neutron-l3-agent-POSTROUTING ! -i qg-36d2c33f-78 ! -o qg-36d2c33f-78 -m conntrack ! --ctstate DNAT -j ACCEPT
-A neutron-l3-agent-PREROUTING -d 169.254.169.254/32 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9696
-A neutron-l3-agent-snat -j neutron-l3-agent-float-snat
-A neutron-l3-agent-snat -s 10.10.1.0/24 -j SNAT --to-source 192.168.7.40
-A neutron-postrouting-bottom -j neutron-l3-agent-snat

Please help here.

2013-06-25 03:05:31 -0600 asked a question Adding another compute node on GRE topology

Hello, currently i have working openstack project with just one compute node, the configuration and topology is follow here https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst, with little bit custom configuration. The point is, how can i add more compute node in that topology? i want to use switch (unmanaged) instead of direct connected to network node, is that possible? i know i can used vlan but it must used manageable switch.
