Hello,

Thank you for taking time  !

Well on the compute node, when i activate "vif_plugging_is_fatal = True", the vm creation stuck in spawning state, and in neutron server log i have :

=======================================

Well I'm supposed it's related ... Perhaps with those options in neutron.conf : 
======================================
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
nova_url = http://localhost:8774/v2
nova_admin_tenant_name = services
nova_admin_username = nova
nova_admin_password = nova
nova_admin_auth_url = http://localhost:35357/v2.0
======================================

But well didnt see anything wrong ...

Thank you in advance !

Looks like HTTP connection to neutron server is resulting in 401 error.

Try enabling debug mode for neutron server and then tail /var/log/neutron/server.log , hopefully you should get more info.

Hello,

Ok I see. Nova telles neutron/openvswitch to create the bridge qbr prior to the migration itself.
I ve already activate debug and verbose ... But well i'm really stuck, dont know how and where to search/look ...

Hi Benoit,

  A manual virsh migration should fail, because the
network ports are not migrated to the destination host.

  You must investigate on the authentication problem itself,
and let nova handle all the underlying API calls which should happen...

  May be it's worth setting nova.conf to debug=True

Subject: [Rdo-list] Icehouse multi-node - Centos7 - live migration failed because of "network qbr no such device"


Hello,

I'm working on a multi-node setup of openstack Icehouse using centos7.
Well i have : 
  - one controllor node with all server services thing stuff
  - one network node with openvswitch agent, l3-agent, dhcp-agent
  - two compute node with nova-compute and neutron-openvswitch
  - one storage nfs node

NetworkManager is deleted on compute nodes and network node.

My network use is configured to use vxlan.  I can create VM, tenant-network, external-network, routeur, assign floating-ip to VM, push ssh-key into VM, create volume from glance image, etc... Evrything is conected and reacheable. Pretty cool :) 

But when i try to migrate VM things go wrong ...  I have configured  nova, libvirtd and qemu to use migration through libvirt-tcp.
I have create and exchanged ssh-key for nova user on all  node. I have verified userid and groupid of nova.

Well nova-compute log, on the target compute node, : 
2014-07-11 11:45:02.749 6984 TRACE nova.compute.manager [instance: a5326fe1-4faa-4347-ba29-159fce26a85c] RemoteError: Remote error: Unauthorized {"error": {"m
essage": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}


So well after searching a lots in all logs, i have fount that i cant simply migration VM between compute node with a simple virsh :
virsh migrate instance-00000084 qemu+tcp://<dest>/system

The error is : 
erreur :Cannot get interface MTU on 'qbr3ca65809-05': No such device

Well when i look on the source hyperviseur the bridge "qbr3ca65809" exists  and have a network tap device.  And moreover i manually create qbr3ca65809 on the target hypervisor, virsh migrate succed !

Can you help me plz ?
What can i do wrong ? Perhpas neutron must create the bridge before migration but didnt for a mis configuration ? 

Plz ask anything you need !

Thank you in advance.


The full nova-compute log attached.
