[Rdo-list] Fwd: [Openstack] ODL integration with Openstack neutron

Monday, 3 August 2015

Hi,

Thanks a lot . That certainly solved my problem. :)
But another problem crept in. Now I am no longer able to launch VM or for
that matter do any thing with my neutron (i.e creating a new network).

Following are the log files on launching the vm:

/var/log/neutron/server.log

Though on dashboard I get the error "Please try again later [Error: No
valid host was found. There are not enough hosts available.]. "
But on analysing the log file I see
*Mechanism driver 'opendaylight' failed in create_port_postcommit *.
Btw I am using ODL Helium release SR3 and log file karaf.log throws this
error

Can anyone help me out here to debug this issue.

Regards,
Saurav

 Hi

 Different openflow version configuration in ODL and OVS causes this issue.

 Set OVS to use all openflow version, so that ODL and OVS can negotiate and
 converge to one common openflow version.

 Hi,

 I have a allinone setup of RDO openstack following the
 https://www.rdoproject.org/Quickstart.

 Now I want to integrate ODL with this, so I followed this guide
 https://www.rdoproject.org/Helium_OpenDaylight_Juno_OpenStack

 My ovs switch setup looks like this. My node IP is 172.18.50.200 and ODL
 is installed on this.

 I am able to login to ODL dashboard and also able to see the necessary
 nodes on it.

 Problem is My VM does not get the IP from the DHCP pool configured. Though
 at dashboard, IP is shown but on VM console It is not visible.Hence I am
 not able to ping the VMs. If I manually add the same IP to the VMs and add
 flow entry  to br-int, then only I am to ping.

 Can anyone please help me out here, as why IP is not getting assigned to
 VM and on manully adding IP, controller is not coming into picture.

 Regards,

 Saurav
