Synnefo

Update GANETI_DISK_TEMPLATES setting description

Describe how to set ext disk template provider.

Networks list api response fix

include deleted networks in reponse if changes-since parameter is set. This
enables ui application to identify deleted networks and remove them from
user interface.

Fix html typo

Fix servers api list response

filter out deleted vms !!!!!!!

Add check for maximum secret encryption key

SECRET_ENCRYPTION_KEY can be up to 32 bytes long, since bigger keys are
not supported by AES encryption. Add comment to the setting and better
message to exception.

Rename setting

Rename ENCRYPTION_KEY to SECRET_ENCRYPTION_KEY to prevent from being
displayed at django debug traces.

Revert "Start pool indexing from 0"

This reverts commit 2f998a3756c6fc7ddce9e0f83dea738e473320b8.

Start pool indexing from 0

Management command for removing backend

Fix serious bug in reconciliation

Do not perform reconciliation for VMs that are hosted in Backends
that are currently offline, since it is impossible to get the
state of these VMs from the backend. Before this patch, the
reconciliation mechanism would report these VMs as stale (and with...

Store action when creating a network

Warning about missing setting to migration file

Get public network by public attribute

Do not find the public network by the primary key, as the initial_data.json
is obsolete. Instead, ise the public attribute of the Network Model.
Currently only one public Network is supported, and the used can not
create or delete the public Network. But this can easily change in the...

Fix creation of networks in new backend

Add missing setting

Add PRIVATE_PHYSICAL_VLAN_TAGS setting

Setting for using IP Pool to public network

Introduce new setting 'PUBLIC_ROUTED_USE_POOL', to indicate whether
synnefo will be responsible for the IP management of the public network,
or this responsibility will be delegated to Ganeti.

Fix case of empty address pool

Limit allowed network size

Limit the size of networks that users can create, since big IP
pools can have negative impact on performance. Allowed network
size is controled by 'MAX_CIDR_BLOCK' setting.

Implement model manager using row-level db locking

Implement ForUpdateManager that uses SELECT .. FOR UPDATE statement in
order to acquire row-level exclusive locks to DB. Essentially this
manager backports the select_for_update() method that is implemented in...

Fix IP pool exceptions

Use ForUpdateManager to Pool objects

Release IP addresses when nics are destroyed

New management command for creating a network

Create a management command for creating networks. Also remove
the initial_data.json, since it is currently not necessary.

Implement IP management

Delegate IP management to synnefo, in order to be able to allocate IP
addresses accross multiple Ganeti backends. This is achieved by creating a
Pool of IPs for each Network, in the form of a bitarray, which is stored
in the DB as a base64 string....

Filter deleted entries when changes-since is used

Modify list_networks and list_servers to filter deleted entries when
if-modified-since HTTP header is used, because deleted entries can be
updated after deletion through the reconciliation mechanism.

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 the
ENCRYPTION_KEY setting. After modifying this setting, synnefo will be
unable to decrypt already stored passwords, and passwords must be...

Add dirty bit to NetworkInterface

Extend NetworkInterface model with a dirty bit, indicating whether
the index of the NIC is consistent with the one in Ganeti. This flag is
set when deleting a NIC, and is switched off after processing the
notification from Ganeti. Removing a NIC with the dirty bit on is not...

When creating network, the label subnet can now be cdir in the json request

Remove machine if ganeti job fails

Set the VM deleted flag when receiving a failure notification for a
Ganeti OP_INSTANCE_REMOVE operation, even if the VM operstate is not
ERROR. The server may not exist in the backend not only because the
creation failed, but also because a remove notification was lost.

Cyclades UI integration with the new networks api

- Handles nic connections instead of vms. New NIC model and NICs
collections created to handle the NIC api logic. NIC models get
updated on each vms/networks api call.
- New private network creation form....

Implement network reconciliation

Update management commands for new-style networks

Fix use of network name prefix

Fix bug about unknown network in instance's nics

Fix bug in networks api

Fix bug in dispatcher callback

During handling of ganeti-op-status messages, state was set to error
only if the the opcode was OP_INSTANCE_CREATE. This resulted to
vm's never being deleted, if they did not exist in Ganeti.

Set index of NetworkInterface model to not null

Modification in logic for new-style networks

Rename backend_create to backend_add

Major modifications to Network model

Since Ganeti version 2.6, Ganeti is aware of private networks. We take
advantage of this by propagating network handling to Ganeti. Network
model is expanded to include information about the type of network
(public routed, physical vlan, private filtered), subnet, gateway, dhcp,...

Remove stale save's in db

Implement backend allocator and management command

New module implementing instance allocation to one of the available
backends. Allocation is performed based on memory and disk utilization.
Statistics for each backend are stored in DB and updated periodically....

Use the Backend client instead of global RAPI

Replace use of global RAPI client, with the cached client from the
VirtualMachine or Backend model.

Dispatch network actions to all backends.

Create Backend model to represent a ganeti backend

- Create Backend model holding info about credentials, status and resources
- Add Backend as foreign key to VirtualMachine
- Create a cache of Backend clients (RAPI) for better performance

Fix white space and PEP8
