Re: [Openstack] [openstack] how to configure quantum so that two private network can ping each other?
Thanks so much for the info. The command ‘iptables -t filter -I FORWARD -i qbr+ -o qbr+ -j ACCEPT’ helped. However, it’s temporary. After I issued this command, I was able to ping from vm1 to vm2. After about 10 mins, I could not ping again. How to make this rule permanent? I’m using Ubuntu LTS 12.04. Thanks, YuLing From: p...@juyide.com [mailto:p...@juyide.com] On Behalf Of ??

Re: [Openstack] [openstack] how to configure quantum so that two private network can ping each other?
Thanks Ashok. I've already executed the following two commands: nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0 nova secgroup-add-rule default tcp 22 22 0.0.0.0/0 However, it still didn't help. I can see that vm1 can ping vm2's gateway, and vice versa. Just vm1 could not ping vm2. Could it be cirros issue? Will it make any difference if I use a different vm image?

[Openstack] OVS plugin
Hi All, I was wondering if anyone could help me with a question related to the guideline of Quantum plugin development. Let's say if we need to develop a quantum plugin and we would need to use OVS plugin in our plugin. Is it a good practice to change the code of OVS plugin when we need to, or we should preserve the OVS plugin and only add code on top of it? Or in another word, if we would need to contribute back our quantum plugin to OpenStack, will there be any issue if we changed OVS plugin in our solution?

Re: [Openstack] anyone has a sample quantum.conf file that configures a valid quantum.log file?
Thanks very much Maru. Another question...I'm playing around with Openstack Dashboard. What I can see is that after I launch a VM, a few ports will be created. Port details would also show the MAC address of the port(something like fa:16:3e:97:1f:b7). Is this MAC address the physical MAC address of the port on the NIC card? If not, what MAC address is it?

Re: [Openstack] anyone has a sample quantum.conf file that configures a valid quantum.log file?
I guess that's not physical either... since ifConfig -a on the Ubuntu OS(where my VM resides) gave me different HWaddr (something like 5a:86:eb:95:1a:49). So, another question is whether I can get the physical NIC port MAC from Openstack Quantum? The plugin configured in my environment is OVS plugin.

Re: [Openstack] anyone has a sample quantum.conf file that configures a valid quantum.log file?
Hi Maru, Actually in VMWare case, we will be able to see the physical NIC port address from VCenter(View Network Adapters in Configuration tab of the physical cluster node). I'm not sure how I can get the same information in OVS case... When you mentioned 'it can obviously be discovered manually', what exactly did you refer to?

It is not possible to retrieve the physical mac port as you desire via Quantum's API. The mapping of physical NIC to virtual NIC is plugin-specific and not exposed, though it can obviously be discovered manually. What use-case are you thinking of that requires discovery of the physical mac that is transiting traffic for a given VM?
