Remove code handling networks from network API views to logic.networks
cyclades: Make NIC representation more verbose
cyclades: Add FloatingIP model
Add Floating IP model to represent a floating IP that has been reservedby a user. Each FloatingIP has an owner(UUID), an IPv4 address, thenetwork(pool) that has reserved from and the date is was reserved. Also,it may be related to a VirtualMachine, if there is some VM that uses...

Major refactor to cyclades api and logic apps that removes most codefrom the api views and moves it to logic app, so that the same logiccode can be used by different apps (e.g. EC2 API). Code is moved into...
cyclades: Implement resize action API call
Implement resize API call, which is a POST at/servers/<server_id>/action' with body: {"resize": {"flavorRef": <flavor_id>}}
The resize can only be performed if the disk size and disk template ofthe new flavor are the same with the old one, and if the VM is in...

Fix bugs in models methods
Do not allow creation of more than one pools
Do not allow creation of more than one Bridge or MacPrefix pool, sincewe can not handle them yet.
Introduce network flavors to replace network types

Fix bugs from merging
Reorder code
Create QuotaHolderSerial table
Add QuotaHolderSerial column to VM and Network
Correlate the VirtualMachine and Network models with a QuotaHolderSerialentry, holding the serial number returned by the QuotaHolder for thelast allocation for these resources.
Do not automatically update network state
Each modification in a BackendNetwork object, triggers an updateto the corresponding Network object. Until now this was done bythe BackendNetwork save() method. Now it is explicitly donefrom the backend pross_network_status.
Add indexes to VirtualMachine and Network
Add indexes to VirtualMachine userid and deleted columnsAdd indexes to Network userid, deleted and public columns
Use select_for_update for VirtualMachines
Use select_for_update method when accessing VM objects to preventrace conditions. Also move start_action from logic to api.
Delete BackendNetworks when deleting a Backend
Merge branch 'ui-0.11' into devel-0.12
Do not allow actions to deleted networks
Merge branch 'devel-0.12' into ui-0.11
Restore IP Pool creation for corner cases
Create IPPool when creating Network
Create the IPPool associated with each Network, when creating it. Untilnow, IPPools were created on first demand. However, because the Networkobject is not accessed in exclusive mode, concurrent access to theNetwork model resulted in a race condition. More than one workers may...

Implement MAC Prefix Management
In order to guarantee uniqueness of MAC address accross all backends,synnefo assignes a unique mac prefix to each network in each backend.
A mac-prefix of 20 bits, which is picked from the MacPrefixPool, isassigned to each Network. The mac-prefix of the network in each...
Release resources of Network only on deletion

Implement IP management
Delegate IP management to synnefo, in order to be able to allocate IPaddresses accross multiple Ganeti backends. This is achieved by creating aPool of IPs for each Network, in the form of a bitarray, which is storedin the DB as a base64 string....
Update network settings
Encrypt Backend password
Use cipher to encrypt the passwords of the Ganeti backends in the DB.Encryption/decryption is based on a configurable key, defined by theENCRYPTION_KEY setting. After modifying this setting, synnefo will beunable to decrypt already stored passwords, and passwords must be...
Add dirty bit to NetworkInterface
Extend NetworkInterface model with a dirty bit, indicating whetherthe index of the NIC is consistent with the one in Ganeti. This flag isset when deleting a NIC, and is switched off after processing thenotification from Ganeti. Removing a NIC with the dirty bit on is not...
Common functions for instance/network backend name

Set as available in the pool the bridge and mac prefix that wasused by the deleted network.
Bug fixes concerning networks
Set index of NetworkInterface model to not null
Major modifications to Network model
