Hi Jaime,<br>
<br>
It is happening for all the interfaces and we are using the bridging
compatibility layer, but what we have defined in the template as
network mode is openvswitch, not default (bridge).<br>
This might be a case of use where the physical machines just power
on.<br>
<br>
<br>
Regards,<br>
<br>
Carlos.<br>

<div style="">the expected behaviour is for the vnet to go away
after the VM shuts down (the hypervisor should run brctl delif

of them? are you using the bridging compatibility layer?</div>

We're running OpenNebula 3.8.3 with Open vSwitch and we've
found out an issue. Once the frontend and the host are
started, the VMs appear in Pending state and move to
Prolog and again back to Pending states.<br>

We've realised that one tries to create a vnetx but that
vnet interface is already into the Open vSwitch database,
so it is unable to introduce that interface and therefore
to create the VM. This is the output of the openvswitch:<br>
<i><small>#ovs-vsctl show<br>
6725e67a-3af1-4fdf-9dfe-f606d09918a8<br>
Bridge "vbr1"<br>
Port "bond0"<br>
Interface "bond0"<br>
Port "vbr1"<br>
Interface "vbr1"<br>
type: internal<br>
ovs_version: "1.4.3"</small></i><br>
<br>
We've managed to solve it manually deleting those
interfaces into the open vswitch database and immeditely
one has been able to create the VMs.<br>
This is the output:<br>

Is there any way to manage it? We've thought on an script
to automatically check it everytime we restart the
servers, but perhaps there is already a better way we
unknow.<br>

Thanks in advance,<br>
