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.
This fixes the agreed upon url on download.cloudstack.org in various
sql files and misc scripts.

CLOUDSTACK-9619: Updates for SAN-assisted snapshotsThis PR is to address a few issues in #1600 (which was recently merged to master for 4.10).
In StorageSystemDataMotionStrategy.performCopyOfVdi we call getSnapshotDetails. In one such scenario, the source snapshot in question is coming from secondary storage (when we are creating a new volume on managed storage from a snapshot of ours thats on secondary storage).
This usually worked in the regression tests due to a bit of "luck": We retrieve the ID of the snapshot (which is on secondary storage) and then try to pull out its StorageVO object (which is for primary storage). If you happen to have a primary storage that matches the ID (which is the ID of a secondary storage), then getSnapshotDetails populates its Map<String, String> with inapplicable data (that is later ignored) and you dont easily see a problem. However, if you dont have a primary storage that matches that ID (which I didnt today because I had removed that primary storage), then a NullPointerException is thrown.
I have fixed that issue by skipping getSnapshotDetails if the source is coming from secondary storage.
While fixing that, I noticed a couple more problems:
1) We can invoke grantAccess on a snapshot thats actually on secondary storage (this doesnt amount to much because the VolumeServiceImpl ignores the call when its not for a primary-storage driver).
2) We can invoke revokeAccess on a snapshot thats actually on secondary storage (this doesnt amount to much because the VolumeServiceImpl ignores the call when its not for a primary-storage driver).
I have corrected those issues, as well.
I then came across one more problem:
When using a SAN snapshot and copying it to secondary storage or creating a new managed-storage volume from a snapshot of ours on secondary storage, we attach to the SR in the XenServer code, but detach from it in the StorageSystemDataMotionStrategy code (by sending a message to the XenServer code to perform an SR detach). Since we know to detach from the SR after the copy is done, we should detach from the SR in the XenServer code (without that code having to be explicitly called from outside of the XenServer logic).
I went ahead and changed that, as well.

CLOUDSTACK-9627 Fix template sync for region store.When using a region store like Swift or S3 as secondary storage,
the `zoneId` can be null. This causes an exception when we try
to convert it to a `long`. This fix guards against that.
Before this fix, if you restart the management server, all the templates
would change to "NOT READY" because the code which syncs the NFS cache
and the object store crashes due to the above mentioned issue.
This PR fixes that.
