cyclades: Fix reconciliation for network and pools

Fix reconciliation to work with multiple IP pools per network:
  • Fix reconcile-networks command to check if a reserved_ip in a Ganeti
    network is reserved in the pool that contains this IP (if any)
  • Fix reconcile-pools to reconcile each of the networks IP pools and...

cyclades: Refactor backend code for new networks

  • Optimize DB queries by using prefetch related for NIC IPs.
  • Do not try to construct new NIC if it does not exist in Cyclades DB.
  • Update tests

cyclades: Make logic tests pass

Refactor Cyclades code so that it follows the new models for Networks,
Subnets and IPAddresses. This refactor is not complete. Instead is the
necessary refactor for making tests for server API calls succeed.

cyclades: Include 'index' when comparing NICs

cyclades: Ignore Ganeti NICs with unknown ID

Do not process Ganeti NICs that do not have a valid ID and so are
unknown to Cyclades, because processing these NICs would require to
create them in DB and then rename them in Ganeti with the corresponding

cyclades: Use NIC UUID in firewall tags

Use NICs UUID instead of index to generate firewall tags. Make the
'set_firewall_profile' action to take the NICs ID as argument. Also,
update the firewall settings.

cyclades: Use UUIDs to update VM NICs

Callback functions of snf-dispatcher updated the NICs of a VM by
deleting all NICs from DB, and creating the new NICs that were described
in the message. However, since NICs have UUIDs, this is no longer
required. This commit update callbacks to update the NICs based on their...

gtools: Make eventd send job fields

Make snf-ganeti-eventd send 'job_fields' for instance and network
opcodes, and modify the corresponding backend functions and
snf-dispatcher callbacks.

cyclades: Make reconciliation timeouts constants

Remove hard-coded timeouts from code and make them constants. Also do
not perform reconciliation for recent building NICs.

Fix compatibility issues with ganeti-2.7

  • SimpleConfigReader has been removed. Use SimpleStore
  • QUEUE_DIR has been moven from ganeti.constants to ganeti.pathutils
  • _QueuedJob.Restore takes 2 more arguments
  • Group info is returned as list instead of string

cyclades: Refactor reconciliation of pools

Move reconciliation of IP pools from 'snf-manage reconcile-networks'
to 'snf-manage reconcile-pools'. Also change the way reconciliation
works: Instead of reconciling the IP pools in DB with the IP pools in
Ganeti, the new reconciliation just checks that:...

cyclades: Fix bug in reconciliation

VMs at building error that do not exist in Ganeti must not be reported
as stale. The VM is stale only if the user has asked to destroy the VM,
and so the action is DESTROY.

cyclades: Reconciliation for pending vm tasks

Extend reconciliation mechanism, to detect instances with stale pending
tasks, by looking if the corresponding job, 'vm.task_job_id', is still
running in the Ganeti backend.

Also refactor code that performed reconciliation for buildign vms, to...

Move NetworkReconciler class from network-create command to
reconciliation module.

cyclades: Fix reconciliation of building vms

When reconciling a building vm, you first have to reconciliation it's
creation and then it's operstate. Otherwise it is possible to end up
having wrong quotas.

cyclades: Parallel server reconciliation

Major refactor to reconcile-servers management command to make it work
in parallel for each backend. Also, removed all --detect options, and
detect all incosistencies by default.

cyclades: Fixes relative to reconciliation

Get available backends once and work only with them, since available
backends may change during reconciliation. Also temporary remove support
for communicating with each backend in a separate process.

cyclades: Speed up server reconciliation

Speed up reconciliation, by increasing the time interval to get Ganeti
job status for VMs in building state.

Fix reconciliation for building VMs

Since commit 482c645, a VM exists in the Cyclades DB before the
corresponding job is enqueued in the Ganeti backend. Therefore, there is
a corner case, where Cyclades can not enqueue the job to Ganeti and
Cyclades crashes before deleting the VM from the DB, which results in a...

Fix bug about RAPI client pooling

Modify the pooled_rapi_client context manager to handle exceptions
and release the client in any case. Also modify uses of reconciliation
to handle exceptions inside the scope of the context manager

Pool Ganeti RAPI clients

- Move Ganeti RAPI client from snf-common to snf-cyclades-app/logic.
- Create GanetiRapiClientPool for pooling GanetiRapiClient objects
- Create context manager in db.models for pool handling
- Update code using the RAPI client

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...
