cyclades: Fix default/forced server networking

Fix the default behaviour for networking of servers that are being
created. There are two settings controlling this behaviour:

  • CYCLADES_DEFAULT_SERVER_NETWORKS: This setting contains list of
    networks to connect a newly created server to, if the user has not...

cyclades: Create server in public net with FIP

Remove 'floating_ips' extension attribute to POST /servers API call.
Instead use the 'fixed_ip' attribute of 'networks' attribute to specify
the IPv4 address of a floating IP. So in order to create a server
connected to a private network and a public network, the 'networks'...

cyclades: Create server with existing ports

Extend POST /servers API call to support creation of servers that will
be using existing ports. Networking of the instance is defined via the
'networks' attribute which can contain either network UUIDs or port
UUIDs. In case of network UUIDs, the user can also request for a...

fae6e5f0 11/01/2013 04:17 pm Christos Stavrakakis

cyclades: Create ports without 'device_id'

Allow creation of ports that are not connected to any instance. Such
ports will be in 'DOWN' state. To allow this, 'machine' attribute of
NetworkInterface model has been made to allow null values. Finally, the
'logic.ports' module has been remove, and the corresponding code has...

cyclades: Optimize DB queries of /servers API

Use 'prefetch_related' attribute of Django queryset to prefetch the
NetworkInterface and IPaddress objects that are related with a
VirtualMachine object. Also, modify functions that operate on server
NICs and IPs, to to use only the prefetched objects, which means that...

cyclades: Make API server 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: 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.

c988fcca 10/09/2013 11:40 am Christos Stavrakakis

cyclades: Change format of 'attachment' attribute

Change the format of the 'attachment' attribute. Until now, each
attachment had an identifier of the form 'nic-$vm_id-$nic_id'. This
commit changes the identifier to just '$nic_id', since from now on
is unique for the lifetime of a NIC.

cyclades: Add 'ip_type' attribute to NIC

Extend NetworkInterface model with the 'ip_type' attribute to show
whether the IP is a floating or fixed.

cyclades: Use Ganeti NIC UUIDs

Since Ganeti 2.8, it is supported to refer to devices (NICs and Disks)
not only by their index but also by their name or UUID. This commit
updates Synnefo to refer to devices by their name. Synnefo will set the
name of the devices which will be a UUID. We do not use Ganeti's UUIDs...

cyclades: Mock vm removal if creation fails

In case creating a VM fails before the OP_INSTANCE_CREATE job is
enqueued in Ganeti, the VM and its NICs must be deleted, and the
resources must be released from Quotaholder, which is exactly what is
done when a VM is deleted from Ganeti. Instead of duplicating the code,...

object becomes stale: its lock is released and another thread may acquire...

cyclades: Make index field of NIC optional

Change 'index' field of NIC model to be optional, because the index of
building NICs is unknown. Also, change all API responses to return only
the active NICs.

cyclades: Fix bug in handling of reboot type.

'type' attribute of reboot OS API call was directly mapped to the
'reboot_type' option of Ganeti reboot job. However these two are
semantically different. The 'SOFT' and 'HARD' reboot types of OS API are
mapped to 'shutdown_timeout' option of Ganeti jobs. However, setting...

cyclades: Set firewall profile per NIC

Set firewall profile per NIC, because since Floating IPs an instance can
have more than one NICs in a public network. Extend the API call to take
the NIC index as argument, and modify the Ganeti instance tags to be
formated with the NIC index.
