Nova commit [1] has changed the format of the block_device_mapping.
We need to adapt our way how we get the list of host wwpns.

VLAN networking is not supported by nova-dpm. This patch
introduces a new exception that is thrown if somebody tries
to connect a DPM instance to a VLAN network.

When a invalid vif_type was given, we used to throw a generic
exception. This patch introduces a new specific exception
InvalidVIFTypeError.

We now can add all NICs with a single command!
This is also usefull once we might introduce ssc support which
requires additional verifications cross all nics.

Patches [1][2] confused block_device_info (bdi) with
block_device_mapping (bdm). We always need the bdm. Nova_dpm's spawn
method now transforms the passed in bdi into a bdm.

This patch modifies the method prep_for_spawn
* Making it private -> _prep_for_spawn
* Removing unused parameters
Change-Id: Ie2e2259badef350082b150b7989a93e85c09e9db
In prep_for_spawn we checked if the an image was provided
during launch. If so we aborted. This check is redundant, as we already
check this in _get_partition_instance.
The Unittests are still correct!
Change-Id: Idfee4d6dd80043c9a468b42c7b33dc7669a2529d
For some actions (e.g. downloading an image) we need the context
to be present in PartitionIstance. This patch introduces
the context property in this class. In addition context is set
during launch.
It is not required during other operations for now.

Till now the String was generated and set from the driver class.
This patch moves both actions into the PartitionInstance class.
This allows us overwriting this method once we support another
partition type (e.g. ssc).
Change-Id: If535cbdcdf878f5e9e2f91d0f0d1128021efcbbc
For each nic we need to add some data to the partitions
boot-os-specific-parameters property. Till now we were accumulating
everything to a single string which set the property once. The new
approach is to update the property for each nic.
This leads to more read/write accesses on this partition property. But
on the other hand we're gaining flexibility. E.g. someone might want to
add a NIC after spawn. Or some other data should be added. Those
scenarios were not supported in the past.
This is also helpful to move this code into the partitioninstance
class. In the future this action might not be required for all type of
partitions (e.g. not for ssc).
Change-Id: I0262f2660b3e89b455bb1b1ece016342c8347c80
We extract the pieces that generate the nic dict from the attach_nic
method into a separate method. This allows overwriting the creation
of the dict once we support for example ssc.

The DPMVIF object represents a VIF (virtual interface for networking).
Nova provides us a large dictionary. This object provides a better method
to access properties of a vif.

We build up all the properties required for boot now in the
vm class. The driver does not need to deal with gathering
information for boot anymore.
Change-Id: Iad15a7a404a3467d417f27e739a3e4dc7233af6f
This object should simplify the usage of the block_device dictionary
provided by nova. Attributes can now easily be accesed via object
properties and method, instead of doing complex operations on the dict.
This patch does not yet exploit this object. This is done in a follow
up patch.

The set_boot_hba uri method can determine the boot-hba-uri on its own
as this information is available in the object instance.
Change-Id: I39f15db7865457a7e91452e7a024bc4944a5317b
In some cases we need the hba object to retrieve the wwpn of
the hba used for boot, in some the element-uri. We had 2 different
ways of gathering this information.
This patch transforms the get_boot_hba_uri method into a more generic
get_boot_hba method. From this object it's easy to retrieve the
required properties 'element-uri' and 'wwpn'.

In some methods we directly created an instance of the PartitionInstnace object.
The instantiation of this object is now moved into a separate method. This is
even more usefull when we introduce ssc support in the future. In that case
we could simply introduce a SSCPartitionInstance class. The newly created method
would be the only place where the decission between ssc and pure dpm is done.

Following updates are made to the signature of spawn method and its
corresponding references in test_driver.py.
- add "allocations" kw arg as per [1]
- remove "flavor" kw arg as per [2]

It seems nova removed 'instance.instance_type_id'
by which we were getting flavor.
Now instance has 'instance.flavor'.
Direct access of flavor.

With the current local.conf it is not possible to use floating-ips
to access an instance.
This patch extends and refactors the local.conf, that devstack creates
2 networks. A public network (used for floating ip) - public, and a
private network where the instances get attached to - provider.
In addition the ovs is configured to be able to deal with both networks.
However one manual step is required. The bridge br-provider needs to be
created manually before stack.sh is run.

When we do inband shutdown of partition using
command 'shutdown -P now'
Then partition is not going to 'stopped' state.
It is going to 'PAUSED' state.
In DPM there is no such implementation so that we
can start partition from PAUSED state. So workaround
is we need to stop the partition then start.
This patch also includes the cases when partition is
in "starting/stopping" state.

This is in connection with the minimum value assigned to the max-memory
parameter in local.conf under dpm section.The default value of
reserve_host_memory is 512Mb by which it blocks 512Mb of memory on the
host this means to launch an instance on a host 1024 is the minimum
memory that is needed as 512Mb is being reserved inorder to mitigate
this issue the reserved memory is made 0.
