Guys, I followed this guide: https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst to build my latest cloud (PoC) and, from within my Instances, I'm facing some connectivity issues, like this:
--- Instance ip config --- ubuntu@ubu-1:~$ ip r default via 10.100.1.1 dev eth0 metric 100 10.100.1.0/24 dev eth0 proto kernel scope link src 10.100.1.5 --- --- Test #1 - ping google - okay... --- root@ubu-1:~# ping -c 1 google.com PING google.com (74.125.234.110) 56(84) bytes of data. 64 bytes from gru03s08-in-f14.1e100.net (74.125.234.110): icmp_req=1 ttl=57 time=75.7 ms --- --- Test #2 - install ruby gem "bundler" - not okay... --- root@ubu-1:~# gem install bundler ERROR: While executing gem ...

Escape character is '^]'. ^]quit --- But "gem install bundler" always fails... >From within ubu-1's gateway, the "network node" with l3 agent + namespaces, "gem install bundler" works as expected... Weird thing is, I can run "apt-get update / upgrade" without any issues on "ubu-1" instance... Everything is just opened to the Internet... All tenants have this weird problem... I tried different setups but, can't figure it out by myself... I appreciate any help! I'm running tcpdump at the network node, while trying to run "gem install bundler" from within "ubu-1" instance: --- root@network:~# ip netns exec qrouter-475257b2-836c-43a1-98a8-8f29ae1ce1b5 tcpdump -i qr-7a44c1d0-7e --- Output: --- 02:27:42.279268 IP 10.100.1.5 > server-54-230-58-171.gru1.r.cloudfront.net: ICMP 10.100.1.5 unreachable - need to frag (mtu 1454), length 556 more on paste bin: http://paste.openstack.org/show/43153/ --- >From within network node (ubu-1 instance gateway), gem install it works... --- root@network:~# gem install bundler Fetching: bundler-1.3.5.gem (100%) Successfully installed bundler-1.3.5 1 gem installed Installing ri documentation for bundler-1.3.5... Installing RDoc documentation for bundler-1.3.5... --- Any thoughts?! Apparently, the package didn't goes back to the Instance... But I don't know how to fix it... =P I tried a lots of variants of this setup (playing with quantum networks, routers and Floating IPs) but, no success... I can't run "gem install bundler" form within any Instance... But I can navigate, use apt-get update and etc... :-/ NOTE: I noted that the rubygems is hosted at the AWS + CloudFront, and, the IP of it keep changing... It differs a bit from this mail and pastebin that I posted. NOTE 2: The ubu-1 have no Floating IP attached to it, I'm trying to run "gem install bundler" from VNC console after changing "ubuntu" user password... Everything here is based on Ubuntu 12.04.2 + Grizzly from UCA, including Instances (ubu-1) and servers (network, controller, node, etc)... Tks! Thiago
