Hi all,

I had 1 Controller node and 1 Compute node with Juno and recently i add other Compute node, both use nova-network, all nodes use ubuntu 14.04.1, the problem is when i try launch one instance in new server, i have this error in nova-compute log:

Try adding this if not in nova.conf (compute1) yet vif_plugging_is_fatal = False and vif_plugging_timeout=0. Run ovs-vsctl show share the result.

Thanks, i found where is the problem, it's the last version of nova-compute for ubuntu 14.04, i was install the version 1:2014.2.1-0ubuntu1~cloud0 and i must downgrade to 1:2014.2-0ubuntu1~cloud0

Instead of downgrading, take a look at https://bugs.launchpad.net/nova/+bug/1405741 (Bug #1405741).

I have a copy of old version in /var/cache/apt/archives directory, try find in your servers, if not find it i can upload for you. You mast find this files: nova-common nova-compute nova-compute-kvm nova-compute-libvirt python-nova

Jorge Martinez ( 2014-12-23 06:22:41 -0500 )edit

I do not have-it in the archives, can you please upload-it somewhere ?? I'm a little desparate, i have 10 compute nodes and ca use only one because of this problem.. And i can see , so far there are no updates...

TomCat ( 2015-01-05 05:01:41 -0500 )edit

TomCat, it may also help to upgrade controller, or upgrade compute to some newest developer version available. Btw I posted it as a bug, not sure whether it is but anyway check it out:
