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 of
the new flavor are the same with the old one, and if the VM is in...

cyclades: Add 'drained' flag to Network

Extend Network model with the 'drained' attribute, to indicate whether a
network should be used in public IP allocation when creating servers.
This option is only useful for public networks.

cyclades: Sypport backends with Xen hypervisor

Support Ganeti backends with Xen hypervisor:
  • Extend 'Backend' model with the 'hypervisor' attribute, which
    currently can be 'kvm' or 'xen'. Use 'kvm' as default value to
    easy database migration. Also add the corresponding schema migration....
99af08a4 05/13/2013 12:38 pm Christos Stavrakakis

cyclades: Implement lazy networks

Implement "lazy networks", which are not created to all Ganeti backends
upon creation, but only when an instance that resides in a Ganeti is
connected to that network.

Update 'create_network' to create the Network object in DB without...

Fix NIC's default state

Use "ACTIVE" as NIC's default state, to avoid addding a data migration.

939d71dd 03/21/2013 05:05 pm Christos Stavrakakis

Create public NIC when creating VM

Until now, a server's public NetworkInterface was not created in the DB
until the arrival of the message from Ganeti hooks. However, the IPv4
address of the NIC is reserved before sending the OP_INSTANCE_CREATE
job to Ganeti....

Bypass commissioning for orphan networks

Cyclades public networks do not have an owner, and since can not use
the commissioning system. Also, make snf-dispatcher instead of failing
for networks without userid to just a log a warning. This does not apply for...

0816cd46 01/04/2013 11:38 am Christos Stavrakakis

Fix bug about networks and offline backends

Ignore offline backends when computing the state of the network, since
no notification will be received from them. Also, create no
BackendNetwork for an offline backend. This will be created by
reconcilliation, when the backend gets online again.

Introduce network flavors to replace network types

Add tags and mode to network db model. Replace existing type with
flavor. Introduce 4 different flavors. Each flavor has mode, link,
mac_prefix, tags. Supported flavors are CUSTOM, IP_LESS_ROUTED,

Do not automatically update network state

Each modification in a BackendNetwork object, triggers an update
to the corresponding Network object. Until now this was done by
the BackendNetwork save() method. Now it is explicitly done
from the backend pross_network_status.

Create IPPool when creating Network

Create the IPPool associated with each Network, when creating it. Until
now, IPPools were created on first demand. However, because the Network
object is not accessed in exclusive mode, concurrent access to the
Network model resulted in a race condition. More than one workers may...

Refactor IP pools

Treat IP pool the same way as bridge and mac-prefix pools. The pool is
removed from the Network table and moved to an IPPoolTable containing the
IP pools for all networks. Also added support for external reservations.

Migration files for transfering the pool to the new tables are included....

to that design.

Each pool type is mapped to a table in the database, and each row of
that table is a pool of that type. All pool tables must contain the...

New method for creating BackendNetwork entries

Create a new method to the Network model, in order to create the
BackendNetwork entries tha correspond to this network. Also remove
the custom save method, since when multiple public network will be
supported, we want them to be correlated with specific backends.

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, is
assigned to each Network. The mac-prefix of the network in each...

77f0fa63 07/23/2012 11:49 am Christos Stavrakakis

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....

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...

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,...
