Hi all,
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.
This is the output of oned.log:

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:
/#ovs-vsctl show
6725e67a-3af1-4fdf-9dfe-f606d09918a8
Bridge "vbr1"
Port "bond0"
Interface "bond0"
Port "vbr1"
Interface "vbr1"
type: internal
ovs_version: "1.4.3"/
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.
This is the output:

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.
Thanks in advance,
Carlos.
