In case an older SSVM is removed without changing it's state from Up
to Destroyed/Removed etc, the SSVM may be randomly selected for image
store related operations. This fix ensures that endpoints for an image
store are found only from a set of SSVM hosts that are not removed.

Problem: In Vmware, appliances that have options that are required to be answered before deployments are configurable through vSphere vCenter user interface but it is not possible from the CloudStack user interface.
Root cause: CloudStack does not handle vApp configuration options during deployments if the appliance contains configurable options. These configurations are mandatory for VM deployment from the appliance on Vmware vSphere vCenter. As shown in the image below, Vmware detects there are mandatory configurations that the administrator must set before deploy the VM from the appliance (in red on the image below):
Solution:
On template registration, after it is downloaded to secondary storage, the OVF file is examined and OVF properties are extracted from the file when available.
OVF properties extracted from templates after being downloaded to secondary storage are stored on the new table 'template_ovf_properties'.
A new optional section is added to the VM deployment wizard in the UI:
If the selected template does not contain OVF properties, then the optional section is not displayed on the wizard.
If the selected template contains OVF properties, then the optional new section is displayed. Each OVF property is displayed and the user must complete every property before proceeding to the next section.
If any configuration property is empty, then a dialog is displayed indicating that there are empty properties which must be set before proceeding
image
The specific OVF properties set on deployment are stored on the 'user_vm_details' table with the prefix: 'ovfproperties-'.
The VM is configured with the vApp configuration section containing the values that the user provided on the wizard.
Retrieval of an image store using ImageStoreProviderManager has been refactored by introducing three different methods,
DataStore getRandomImageStore(List<DataStore> imageStores);
To get an image store for reading purpose. Threshold capacity check will not be used here.
DataStore getImageStoreWithFreeCapacity(List<DataStore> imageStores);
To get an image store for reading purpose. Threshold capacity check will be used here and the store with max free space will be returned. If no store with filled storage less than the threshold is found, the NULL value will be returned.
List<DataStore> listImageStoresWithFreeCapacity(List<DataStore> imageStores);
To get a list of image stores for writing purpose which fulfills threshold capacity check.
Correspondingly DataStoreManager methods have been refactored to return similar values for a given zone.
Fixes#3287 - NULL value will be returned when secondary storage is needed for writing but there is not store with free space.
Fixes#3041 - Rather than returning random secondary storage for writing, storage with max. free space will be returned.
Fixes#3478 - For migration on VMware, all writable secondary storage will be mounted while preparation.

Problem: When a multi-disk OVA template is uploaded, only the root disk is recognized and VMs deployed using such template only get the root disk provisioned.
Root Cause: The template processor for multi-disk OVA was not used in the template upload processor.
Solution: Added support for local multi-disk OVA template upload. After a multi-disk OVA template is
uploaded, the mechanism that worked on multi-disk OVA templates registered using URL is now also used to discovers and creates data-disk templates in cloud.vm_template table and on the secondary storage.
To enable SSL on SSVMs :
• Upload the certificates like you usually do via the API or UI->Infrastructure tab
• Set the global settings secstorage.encrypt.copy, secstorage.ssl.cert.domain to appropriate values
along with the CPVM ones
• Restart management server (no need to destroy/restart SSVM (or the ssvm agent))
Test cases:
- Upload template and check it creates multi-disk folders on secondary
storage and entries in cloud.vm_template table
- Upload template and kill/shutdown management server. Then restart MS
to check if template sync works
- Copy template across zone of an uploaded template

These boolean-return methods are named as "getXXX".
Other boolean-return methods are named as "isXXX".
Considering there methods will return boolean values, it should be more clear and consistent to rename them as "isXXX".

* Fix the problem at #1740 when it loads all snapshots in the primary storage
While checking a problem with @mike-tutkowski at PR #1740, we noticed that the method `org.apache.cloudstack.storage.snapshot.SnapshotDataFactoryImpl.getSnapshots(long, DataStoreRole)` was not loading the snapshots in `snapshot_store_ref` table according to their storage role. Instead, it would return a list of all snapshots (even if they are not in the storage role sent as a parameter) saying that they are in the storage that was sent as parameter.

* [CLOUDSTACK-10240] ACS cannot migrate a volume from local to shared storage.
CloudStack is logically restricting the migration of local storages to shared storage and vice versa. This restriction is a logical one and can be removed for XenServer deployments. Therefore, we will enable migration of volumes between local-shared storages in XenServers independently of their service offering. This will work as an override mechanism to the disk offering used by volumes. If administrators want to migrate local volumes to a shared storage, they should be able to do so (the hypervisor already allows that). The same the other way around.
* Cleanups implemented while working on [CLOUDSTACK-10240]
* Fix test case test_03_migrate_options_storage_tags
The changes applied were:
- When loading hypervisors capabilities we must use "default" instead of nulls
- "Enable" storage migration for simulator hypervisor
- Remove restriction on "ClusterScopeStoragePoolAllocator" to find shared pools
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration

CloudStack volumes and templates are one single virtual disk in case of XenServer/XCP and KVM hypervisors since the files used for templates and volumes are virtual disks (VHD, QCOW2). However, VMware volumes and templates are in OVA format, which are archives that can contain a complete VM including multiple VMDKs and other files such as ISOs. And currently, Cloudstack only supports Template creation based on OVA files containing a single disk. If a user creates a template from a OVA file containing more than 1 disk and launches an instance using this template, only the first disk is attached to the new instance and other disks are ignored.
Similarly with uploaded volumes, attaching an uploaded volume that contains multiple disks to a VM will result in only one VMDK to being attached to the VM.
FS: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Support+OVA+files+containing+multiple+disks
This behavior needs to be improved in VMWare to support OVA files with multiple disks for both uploaded volumes and templates. i.e. If a user creates a template from a OVA file containing more than 1 disk and launches an instance using this template, the first disk should be attached to the new instance as the ROOT disk and volumes should be created based on other VMDK disks in the OVA file and should be attached to the instance.

This feature allows using templates and ISOs avoiding secondary storage as intermediate cache on KVM. The virtual machine deployment process is enhanced to supported bypassed registered templates and ISOs, delegating the work of downloading them to primary storage to the KVM agent instead of the SSVM agent.
Template and ISO registration:
- When hypervisor is KVM, a checkbox is displayed with 'Direct Download' label.
- API methods registerTemplate and registerISO are both extended with this new parameter directdownload.
- On template or ISO registration, no download job is sent to SSVM agent, CloudStack would only persist an entry on template_store_ref indicating that template or ISO has been marked as 'Direct Download' (bypassing Secondary Storage). These entries are persisted as:
template_id = Template or ISO id on vm_template table
store_id NULL
download_state = BYPASSED
state = Ready
(Note: these entries allow users to deploy virtual machine from registered templates or ISOs)
- An URL validation command is sent to a random KVM host to check if template/ISO location can be reached. Metalink are also supported by this feature. In case of a metalink, it is fetched and URL check is performed on each of its URLs.
- Checksum should be provided as indicated on #2246: {ALGORITHM}CHKSUMHASH
- After template or ISO is registered, it would be displayed in the UI
Virtual machine deployment:
When a 'Direct Download' template is selected for deployment, CloudStack would delegate template downloading to destination storage pool via destination host by a new pluggable download manager.
Download manager would handle template downloading depending on URL protocol. In case of HTTP, request headers can be set by the user via vm_template_details. Those details should be persisted as:
Key: HTTP_HEADER
Value: HEADERNAME:HEADERVALUE
In case of HTTPS, a new API method is added uploadTemplateDirectDownloadCertificate to allow user importing a client certificate into all KVM hosts' keystore before deployment.
After template or ISO is downloaded to primary storage, usual entry would be persisted on template_spool_ref indicating the mapping between template/ISO and storage pool.
This fixes the following:
- Unchecked thread growth in RemoteEndHostEndPoint
- Potential NPE while finding EP for a storage/scope
Unbounded thread growth can be reproduced with following findings:
- Every unreachable template would produce 6 new threads (in a single
ScheduledExecutorService instance) spaced by 10 seconds
- Every reachable template url without the template would produce 1 new
thread (and one ScheduledExecutorService instance), it errors out quickly without
causing more thread growth.
- Every valid url will produce upto 10 threads as the same ep (endpoint
instance) will be reused to query upload/download (async callback)
progresses.
Every RemoteHostEndPoint instances creates its own
ScheduledExecutorService instance which is why in the jstack dump, we
see several threads that share the prefix RemoteHostEndPoint-{1..10}
(given poolsize is defined as 10, it uses suffixes 1-10).
This fixes the discovered thread leakage with following notes:
- Instead of ScheduledExecutorService instance, a cached pool could be
used instead and was implemented, and with `static` scope to be reused
among other future RemoteHostEndPoint instances.
- It was not clear why we would want to wait when we've Answers returned
from the remote EP, and therefore a scheduled/delayed Runnable was
not required at all for processing answers. ScheduledExecutorService
was therefore not really required, moved to ExecutorService instead.
- Another benefit of using a cached pool is that it will shutdown
threads if they are not used in 60 seconds, and they get re-used for
future runnable submissions.
- Caveat: the executor service is still unbounded, however, the use-case
that this method is used for short jobs to check upload/download
progresses fits the case here.
- Refactored CmdRunner to not use/reference objects from parent class.

Snapshots are not deleted resulting unexpected storage consumption in case of VMware.
Steps to reproduce this issue :
In VMware setup, create a snapshot of volume say Snap1.
After successful creation of snapshot Snap1, create new snapshot of same volume say Snap2.snapshots
While Snap2 is in BackingUp state, delete Snap1.
Snap1 will disappear from Web UI, but when we check secondary storage, files associated with Snap1 still persists even after cleanup job is performed.
In snapshot_store_ref table in DB, Snap1 will be in ready state instead of Destroyed.
Also, in snapshots table, status of Snap1 will be Destroyed but removed column will be null and will never change to the date of snapshot removal.
Fix for this issue :
In VMware, snapshot chain is not maintained, instead full snapshot is taken every time.
So, it makes sense not to assign parent snapshot id for the snapshot. In this way, every snapshot will be individual and can be deleted successfully whenever required.
This PR adds an ability to Pass a new parameter, locationType,
to the “createSnapshot” API command. Depending on the locationType,
we decide where the snapshot should go in case of managed storage.
There are two possible values for the locationType param
1) `Standard`: The standard operation for managed storage is to
keep the snapshot on the device. For non-managed storage, this will
be to upload it to secondary storage. This option will be the
default.
2) `Archive`: Applicable only to managed storage. This will
keep the snapshot on the secondary storage. For non-managed
storage, this will result in an error.
The reason for implementing this feature is to avoid a single
point of failure for primary storage. Right now in case of managed
storage, if the primary storage goes down, there is no easy way
to recover data as all snapshots are also stored on the primary.
This features allows us to mitigate that risk.
