2014-06-12 02:58:26 -0600 commented answer Icehouse neutron can't access to instance with floating IP

I'm confused about using floating ip address. when I launch instance using gui, I just assigned private and public network interface at once. I'm sorry about my mistake. So, I launch instance with only private network interface, and then assign floating ip from external network. as a result, i can acess to vm from external network and vice versa. I can aware of my mistake using your ubuntu image. After assign floating ip to instance, i finally found that ip address assigned to interface and nat forwaring rule from qrouter namespace. Thanks for your help. :) And ovs-ofctl result still shows LINK_DOWN status.

Thanks for your answer. I found out that private IP is assigned to instance and can ssh instace with my user account (not root). Instance have two interface but only private interface is up. I tried to give public ip, but can't get root permission. I bulit suse image from susestudio with some root password, but i don't know why root password not works. maybe it's not an neutron problem,, I'm trying to find out any problem in nova or instance image.

I have updated content what you mentioned. ovs qr and qg interface LINK_DOWN status is normal behavior because of netns? I've tried to manually create namespace and ovs interface, but link may also change to down status right after move ovs interface to spcific namespace.

2014-06-11 06:08:12 -0600 asked a question Icehouse neutron can't access to instance with floating IP

Hi, All. I have deployed Openstack icehouse version on RHEL 6.5 for test lab followed by official guideline. After neutron configuration and initiate VM, I can't access to floating IP of VM. Nova instance have two interface for public and private network, I can't access neither of them. So, I can't reach instance. I have tried restart all things and re-configure neutron network. I'm not really familiar with openvswitch and networking, I have thought that i'm missing some important thing. Please help me.

I have two node configuration, first node act as controller, network node and compute node. and second node act as compute node.

Each node have two network interface, one for external and other for private.

**Controller Node and network node and compute node 1 (with External network IP -10.183.120.170)
