This is another method that is causing Jenkins to fail for almost a month
This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.
The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.

* Primary Storage count for an account does not decrease when a Data Disk is deleted
When a data disk is created and not attached in a running VM, the "deleteVolume" will not decrement the count for used primary storage in the VMs accounting information. The property that is not being decremented is called "primarystoragetotal"; this information can be retrieved via "listAccounts" API method.
Steps to reproduce this issue:
1 - Create an account, deploy a VM in it
2 - Check the primary storage count for the account with listAccounts API
3 - Create a data disk
4 - Check the primary storage count for the account with listAccounts API
5 - Delete the Data disk
6 - Check the primary storage count for the account with listAccounts API - It is the same as before deleting the data disk (it should not be the same as the value in step 2!)

* [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

For instance, the class DatadiskTO is supposed to be in com.cloud.agent.api.to package. However, the folder structure it was placed in is com.cloud.agent.api.api.to.
Skip tests for cloud-plugin-hypervisor-ovm3:
For some unknown reason, there are quite a lot of broken test cases for cloud-plugin-hypervisor-ovm3. They might have appeared after some dependency upgrade and was overlooked by the person updating them. I checked them to see if they could be fixed, but these tests are not developed in a clear and clean manner. On top of that, we do not see (at least I) people using OVM3-hypervisor with ACS. Therefore, I decided to skip them.

Allowed zone-wide primary storage based on a custom plug-in to be added via the GUI in a KVM-only environment (previously this only worked for XenServer and VMware)
Added support for root disks on managed storage with KVM
Added support for volume snapshots with managed storage on KVM
Enable creating a template directly from a volume (i.e. without having to go through a volume snapshot) on KVM with managed storage
Only allow the resizing of a volume for managed storage on KVM if the volume in question is either not attached to a VM or is attached to a VM in the Stopped state.
Included support for Reinstall VM on KVM with managed storage
Enabled offline migration on KVM from non-managed storage to managed storage and vice versa
Included support for online storage migration on KVM with managed storage (NFS and Ceph to managed storage)
Added support to download (extract) a managed-storage volume to a QCOW2 file
When uploading a file from outside of CloudStack to CloudStack, set the min and max IOPS, if applicable.
Included support for the KVM auto-convergence feature
The compression flag was actually added in version 1.0.3 (1000003) as opposed to version 1.3.0 (1003000) (changed this to reflect the correct version)
On KVM when using iSCSI-based managed storage, if the user shuts a VM down from the guest OS (as opposed to doing so from CloudStack), we need to pass to the KVM agent a list of applicable iSCSI volumes that need to be disconnected.
Added a new Global Setting: kvm.storage.live.migration.wait
For XenServer, added a check to enforce that only volumes from zone-wide managed storage can be storage motioned from a host in one cluster to a host in another cluster (cannot do so at the time being with volumes from cluster-scoped managed storage)
Don’t allow Storage XenMotion on a VM that has any managed-storage volume with one or more snapshots.
Enabled for managed storage with VMware: Template caching, create snapshot, delete snapshot, create volume from snapshot, and create template from snapshot
Added an SIOC API plug-in to support VMware SIOC
When starting a VM that uses managed storage in a cluster other than the one it last was running in, we need to remove the reference to the iSCSI volume from the original cluster.
Added the ability to revert a volume to a snapshot
Enabled cluster-scoped managed storage
Added support for VMware dynamic discovery
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.
Snapshot on primary storage not cleaned up after Storage migration. This happens in the following scenario:
Steps To Reproduce
Create an instance on the local storage on any host
Create a scheduled snapshot of the volume:
Wait until ACS created the snapshot. ACS is creating a snapshot on local storage and is transferring this snapshot to secondary storage. But the latest snapshot on local storage will stay there. This is as expected.
Migrate the instance to another XenServer host with ACS UI and Storage Live Migration
The Snapshot on the old host on local storage will not be cleaned up and is staying on local storage. So local storage will fill up with unneeded snapshots.
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.
