- one network node with openvswitch agent, l3-agent, dhcp-agent</div><div> - two compute node with nova-compute and neutron-openvswitch</div><div> - one storage nfs node</div><div><br></div><div>NetworkManager is deleted on compute nodes and network node.</div>
<div><br></div><div>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 :) </div>
<div><br></div><div>But when i try to migrate VM things go wrong ... I have configured nova, libvirtd and qemu to use migration through libvirt-tcp.</div><div>I have create and exchanged ssh-key for nova user on all node. I have verified userid and groupid of nova.</div>
<div><br></div><div>Well nova-compute log, on the target compute node, : </div><div><div>2014-07-11 11:45:02.749 6984 TRACE nova.compute.manager [instance: a5326fe1-4faa-4347-ba29-159fce26a85c] RemoteError: Remote error: Unauthorized {"error": {"m</div>
<div>essage": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}</div></div><div><br></div><div><br></div><div>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 :</div>
<div><div>virsh migrate instance-00000084 qemu+tcp://<dest>/system<br></div></div><div><br></div><div>The error is : </div><div><div>erreur :Cannot get interface MTU on 'qbr3ca65809-05': No such device</div>
</div><div><br></div><div>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 !</div>
<div><br></div><div>Can you help me plz ?</div><div>What can i do wrong ? Perhpas neutron must create the bridge before migration but didnt for a mis configuration ? </div><div><br></div><div>Plz ask anything you need !</div>
<div><br></div><div>Thank you in advance.</div><div><br></div><div><br></div><div>The full nova-compute log attached.</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div>Regards,<br>
