Synnefo

Improve exception message when no backends

Various fixes about logging

Fix logging from snf-manage commands. Modify snf-manage implementation
in order to setup the loggers for all snf-manage commands. Configuration
is based on SNF_MANAGE_LOGGING_SETUP setting from snf-common or on
basicConfig if that setting is missing....

Release mac_prefix only if network is MAC_FILTERED

Change and fix migration files

Change network migration, so that it does not allocate a new bridge to
existing network. Instead it keeps the bridges from the old NetworkLink
pool.

Remove network_mac_prefix migration because there are no networks with
mac prefixes....

Change eventd and dispatcher AMQP retries

Set unlimited connection retries to AMQP hosts for snf-ganeti-eventd,
since death of snf-ganeti-eventd results in loss of events.
Also increase retries of snf-dispatcher.

Add missing ipv6 arguments to create_network

Add missing arguments in Backend's get_client

Put synnefo logger of snf-dispatcher to INFO level

Remove user provided names from models unicode

Remove user provided names from models representation, as the user
may provide a value that can affect the admin terminal. Fix suggested
by vkoukis.

Fix bug when not using pool for public networks

Garbage collect GanetiRapiClient pools

Modify the rapi_pool to delete unused GanetiRapiClient pools. This
clients become unused when the credentials of a backend change.

Refresh backends in locked mode

Do not print public networks when adding backend

Add support for Archipelagos/extstorage COW images

Fix bugs in reconcile-networks

Perform logical and instead of or, when merging backend ip maps, since
now the maps are inverted. Also do not report as stale backend networks
that are already deleted.

Perform allocations in separate transactions

Add ForUpdateManager to the Backend model, in order to guarantee
exclusive order when allocating a VM.

Use manual transactions when allocating Backend and public IP for a new
VM, since these allocations need exclusive access (SELECT..FOR UPDATE)...

Merge branch 'public_networks' into devel-0.11

Make snf-dispatcher work with gevent

Remove workers from snf-dispatcher in order to make it compatible with gevent
and specifically the green, monkey patched version of psycopg2
(synnefo.lib.db.psyco_gevent). Also after daemonizing, gevent must be
reinitialized because the deamon context forks.

Change process title to simplify 'ps' display

Use python-setproctitle to change the process title of the running
daemon. Make it appear as a native executable to simplify
administration. Only set executable name, because cannot set individual
values for arguments.

Fix presentation of pools

Fix two bugs in network reconciliation

Fix double logging of dispatcher

Dispatcher had as default handlers the console and the file handler.
However, when daemonizing, we redirect the stdout and stderr to the file
handler, which resulted in the log messages to be printed twice. So we
remove the console handler from the dict configuration, and we only add...

Catch corner case in reconciliation

Catch error produced when the DB entry for an orphan VM in Ganeti does
not exist. This may happen because either an entry from DB was removed
or because a VM in Ganeti with the synnefo prefix was created.

Rename Cyclades management commands for uniformity

Rename Cyclades management commands for uniformity.

Add some logging to backend allocator

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....

Fix bugs in IPPool

- Do not always reserve gateway
- Initial reservations must be in reserved map

Catch error in removing nic

Unique mac-prefix only for mac-filtered networks

Refactor bridge and mac-prefix pool tables

Redesign the implementation of pools and map mac-prefix and bridge pools
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...

Fix bug in snf-manage network-remove

Enable hotplug during create_instance

This passes hotplug = True to ganeti and enables hotplug per instance.
It checks GANETI_USE_HOTPLUG setting.

Allow connecting a VM to a network only if active

Remove dead code

Do not allow creation of two big/small networks

- Networks smaller than /29 are not supported in Ganeti.
- Big networks will result in degraded performance in Ganeti
and DB due to the big reservation map.

Propagate NIC change event to the associated vm

so that nic changed attributes get propagated to the vm views (e.g. nic ip
change).

Revert plankton backend to its original state

trash development code was added by mistake in commit `c6dda6c`

Support for ext disk providers

Extract provider from flavor disk template name and set the additional
`provider` parameter in disk options. Flavor disk_template should be
formated as `ext_<provider_name>`.

Remove spare div from html

Firefox ui fix

add overflow to `hidden` to properly clear upper div in single vm view.

Fix servers api response

do not filter out deleted vms if valid changes-since parameter is set on
the request. This allows ui application to be able to identify and remove
deleted vms.

Fix bug in migration file

Do not allocate a bridge from the pool for deleted networks.

Add setting indicating whether to use hotplug

Update Changelog

New dependencies of snf-cyclades-app

Limit allowed private networks per user

Add command for checking pool consistency

Add new management command 'reconcile-pools' which checks the consistency of the
pools and the uniqueness of the associated resources. Currently this
commands detects the inconcistencies, without trying to resolve them.

Fix migration files

Fix south migration files. In data migrations, access the Models from
the orm, instead importing Models from synnefo.db. This is necessary as
the orm provides access to the version of the models that existed when
the migration file was created.

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...

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...
