cyclades: More strict 'on_delete' for models

Use 'models.PROTECT' for 'on_delete' attribute for some ForeignKey
relationship between networking models. This will create a more "strict"
database and protect for unexpected data loss.

cyclades: Create IPv6 Addresses from dispatcher

When ports are created from the API they do not have an IPv6 address.
The IPv6 address is only available after the MAC address of the
NIC is known which is only available after the message from the
Ganeti backend has been received. However, dispatcher did not created...

cyclades: Series of fixes regarding networks & ips

  • Do not delete the network from the DB if it has associated floating
    IPs. This should never be the case because a check is made before
    deleting the network, however this check is added for safety.
  • Do not allow deleting a network if there are still ports configured on...

cyclades: Major refactor on NIC model

Major refactor on db models concerning NetworkInterface models. A new

cyclades: Use Ganeti NIC UUIDs

Since Ganeti 2.8, it is supported to refer to devices (NICs and Disks)
not only by their index but also by their name or UUID. This commit
updates Synnefo to refer to devices by their name. Synnefo will set the
name of the devices which will be a UUID. We do not use Ganeti's UUIDs...

df8a7015 10/07/2013 02:37 pm Christos Stavrakakis

Commit #f2080d1 mocked an OP_INSTANCE_REMOVE when enqueuing an
