OpenNebula

Hi Patrice,

We've been looking into this... IMHO the basic configuration of OpenVStiwch should be supported out-ofthe box by OpenNebula. I am thinking of the configuration described here:

http://openvswitch.org/?page_id=146

However I am not an expert in OpenVSwitch and I am probably missing something. Could you elaborate a bit what are you missing from OpenNebula?

Cheers

Hi there,

I found that on RHEL-6.1, the vlan device and the bridge device are in the DOWN state when they are created automatically by the hm-vlan hook.
I tracked it down to the ifup function in $ONE_LOCATION/var/remotes/hooks/vnm/HostManaged.rb where the ip command is called. There is a "link" word missing.

The patch is

*** HostManaged.rb    2011-07-04 15:42:11.752812304 -0600
--- /vrstorm/cloudadmin//src/onegit/src/vnm_mad/HostManaged.rb    2011-06-28 13:18:35.918490645 -0600

      def ifup(dev, vlan=nil)
          dev = "#{dev}.#{vlan}" if vlan
!         system("#{COMMANDS[:ip]} link set #{dev} up")
      end
  end

      def ifup(dev, vlan=nil)
          dev = "#{dev}.#{vlan}" if vlan
!         system("#{COMMANDS[:ip]} set #{dev} up")
      end
  end

Please let me know if it makes sense.

Thanks Shi Jin for reporting that bug. Your patch has been applied.

Hi, in fact there is another patch needed to bring up the newly created bridge device.

                  if !attached_bridge_dev?(bridge, dev, vlan)
                      attach_brigde_dev(bridge, dev, vlan)
-                     ifup(bridge)
                  end
              end
          end

That's right Shi Jin. Patch applied. Thanks for testing it.
