Copying preallocated image to volume involves creating
a virtual disk using the image. The virtual disk has a
descriptor and an extent. The preallocated image is used
as the flat extent to create the virtual disk.
To create virtual disk from preallocated image, we first
create a temporary virtual disk (with a descriptor and
flat extent), then replace its flat extent with the
downloaded image. Since vSAN datastores do not support
flat extent, the above operation fails if such a datastore
is selected for virtual disk creation. This patch fixes
the problem by not selecting vSAN datastores for temporary
virtual disk creation.

Catch more general exception in manager's create_volume
When fixing issues with inaccurate allocated_capacity tracking when
create_volume flow fails (Icd6b04ac60c17cbda225d3be8bcc4435ea0cd7a8)

except clause to catch Exception when deciding if rescheduling
occurred while creating a volume. Also regression unit test is added.

Remove LP bug ref in remove_iscsi_device
Some like referencing bugs in code comments, others don't. In
general we try and avoid it, but I certainly don't agree with
blocking a patch solely for that reason. So instead this patch
tries to modify the previous commit to fix it up rather than
having a contest of wills to see who will bend first.
This patch puts a simple check around the 'extra_specs'
key, and makes sure it's there, while trying to inject
the multiattach capabilities filtering.
If we want to change the approach, we can do so in early
Liberty, when we enable multiattach for drivers. At this
stage of the release, lets just do the simple and safe thing.
Some folks are seeing race conditions on overloaded
or slow machines, where the time between issuing the
remove volume command, and the volume being from
/dev/disk/by-path by the kernel isn't long enough.
This patch adds a simple verify loop for iSCSI only.
It will try 3 times and wait 2 seconds between tries.
Also, This patch will only fix attaches that happen
in cinder for copy volume <--> image operations.
Nova needs a separate patch to fix any potential
issues there.

Fix the format of the system name in VMAX driver
There is a change in the format for system name in SMI-S for VMAX V3.
It was "SYMMETRIX+xxxxxx" previously and now it is changed to
"SYMMETRIX-+-xxxxxx". In this patch, the VMAX driver was modified
accordingly to support this format.
Copy volume to image by non-admin user fails with ImageNotAuthorized.
This is because we are setting image's is_public meta-data to True
while calling image update (for writing to image). This patch fixes
this by setting is_public using the image-meta passed in by Cinder.
Note: The oslo.vmware API which we use for upload requires is_public
meta-data which may not be needed at all for writing to image.
Till we update oslo.vmware API, we have to pass a value for is_public.

SMBFS: Fix missing volume provider location
In case of cloning volumes or creating volumes from snapshots, the
volume provider location is not set, making the volumes unusable.
This also leads to disk image leaks, because the delete volume
operation will pass without deleting the disk image if the provider
location is not present.
The SMB driver wraps base RemoteFS methods in order to set locks.
The issue is that it does not return the wrapped method return
value, which signals volume updates, in this case the provider
location.

Enhance VNX Cinder volume creation logic
Sometimes sysadmin needs to remove broken disks and replace them
with some new disks. Before the disks are replaced and fully rebuilt,
the pool would be in "Faulted" state, and all LUNs created in this
pool would be in "Faulted" state as well.
A LUN in this "Faulted" state is still OK for IO access.
Current implementation of create_volume in VNX Cinder Driver will
wait until the VNX LUN gets into Ready State or timeout.
Thus the new volume in the back end corresponding to the pool will
be stuck at creating state for a long time before disks are replaced.
This reduces the high availability of the back end.
The change allows new volume to get into available state as long as
the corresponding VNX LUN can serve IO.

Create unit tests for volume objects

missing unit tests for volume objects. It also adds

context stashed in the object.
We missed an access to volume['instance_uuid']

or not, but checking the new location.

Eager load volume extra specs
The Linux SMBFS driver uses volume extra specs in order to determine
the according image format when creating new volumes.
Accessing the extra_specs attribute can raise DetachedInstanceError
as this attribute is lazy loaded and the session might close by the
time this attribute is accessed.
This can be avoided by simply eager loading the volume extra specs.
The volume manager wasn't being safe with trying to pull an
attachment out of the attachments list. It's possible someone
is calling the manager to detach a volume that has no attachments.
This patch raises an InvalidVolume exception if we detect that
there are no attachments left to detach.
I must have missed this driver in the multiattach
patch. The attachment object is passed in to
detach_volume to give drivers a chance to deal with
a detach call.
This patch just updates the signature of the method
to be the same as the parent.
