The command "quantum update_port" sets the state of the port. In the
case of the ovirt.sh script this sets the port in ACTIVE state.<br>
The "user" is responsible for providing the attachment ID. In the
case of the ovirt.sh script the ID is generated via uuidgen. <br>
Once you have generated a UUID for the attachment you need to pass
this to quantum via the "quantum plug_iface". <br>

A bit of background regarding the script. The purpose of the
POC was to show that Quantum can be run in oVirt. It would
have been ideal to write a REST client that could interface
with the Quantum service. Due to the fact that I was not
familiar with the oVirt code I felt that a quicker and more
productive means was to invoke a bash script from the oVirt
engine code. The script would invoke the quantum cli (this
is a client that configures the quantum server). In addition
to this I did not want to make any changes to the database
schema. The result was a script that does the following:<br>
1. Logical Network Management:<br>
Create:<br>
ovirt.sh network create <name><br>
- the name is the name of the logical network
(in the POC this is prefixed by "Q_"<br>
- this invokes the cli to create a network
called <name><br>
- the UUID returned by the quantum service will
be save in /tmp/network.<name><br>
- the above UUID is read when this logical
network is used (this in the future will be save in the
oVirt data base)<br>
Delete:<br>
ovirt.sh network remove <name><br>
- the name is the name of the logical network
(in the POC this is prefixed by "Q_"<br>
- this invokes the cli to delete a network
called <name><br>
- the file /tmp/network.<name> is deleted<br>
2. VM Port management<br>
Create:<br>
ovirt.sh port create <net_name> <vmid><br>
- the network name and the vm id are input (the
VM id is a key to be able to delete it all :))<br>
- the script does the following:<br>
- creates a port on the network. saves the
port id in /tmp/network.<name>.<vmid>.port<br>
- sets the state of the port to ACTIVE<br>
- creates an attachment ID (this is the line
that you had problems with). This is saved in
/tmp/network.<name>.<vmid>.attachment<br>
- saves the network name in a file
/tmp/network.<vmid><br>
- the UUID's are read when the VM is started
so that they can be passed to VDSM<br>
Delete:<br>
ovirt.sh port remove <vmid><br>
- using the vmid the network name is read =>
enables us to get all of the ID's to delete port in quantum<br>
- cleans all of the files<br>
The script is called from the ovirt engine. Sorry for the
long winded explanation.

In Quantum the attachment ID is generated by the user. The
code above generates the attachment ID for the port. <br>

Do you run the script from the shell or is this run via
oVirt? <br>
There is a log of all of the script command - can you please
look in /tmp/ovirt.txt - this may give us some clues.<br>
You can run the script commands as described above. This may
also help.<br>

oVirt does not support multi tenancy at the

people on the list who can provide more
details about this. The initial<br>

ovirt supports multiple users and an RBAC

Quantum support multi tenancy. The integration with
oVirt was done with the "default" tenant. This is a
different model to that of oVirt.<br>
