(2) download volume. resource count of primary storage is not changed.
(3) expunge the vm, the volume will be Expunged state as there is a volume snapshot on secondary storage. The resource count of primary storage decreased.
(4) update resource count of the account (or domain), the resource count of primary storage is reset to the value in step (2).

Feature Specification: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=95653548
Live storage migration on KVM under these conditions:
From source and destination hosts within the same cluster
From NFS primary storage to NFS cluster-wide primary storage
Source NFS and destination NFS storage mounted on hosts
In order to enable this functionality, database should be updated in order to enable live storage capacibilty for KVM, if previous conditions are met. This is due to existing conflicts between qemu and libvirt versions. This has been tested on CentOS 6 hosts.
Additional notes:
To use this feature set the storage_motion_supported=1 in the hypervisor_capability table for KVM. This is done by default as the feature may not work in some environments, read below.
This feature of online storage+VM migration for KVM will only work with CentOS6 and possible Ubuntu as KVM hosts but not with CentOS7 due to:
https://bugs.centos.org/view.php?id=14026https://bugzilla.redhat.com/show_bug.cgi?id=1219541
On CentOS7 the error we see is: " error: unable to execute QEMU command 'migrate': this feature or command is not currently supported" (reference https://ask.openstack.org/en/question/94186/live-migration-unable-to-execute-qemu-command-migrate/). Reading through various lists looks like the migrate feature with qemu may be available with paid versions of RHEL-EV but not centos7 however this works with CentOS6.
Fix for CentOS 7:
Create repo file on /etc/yum.repos.d/:
[qemu-kvm-rhev]
name=oVirt rebuilds of qemu-kvm-rhev
baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/
mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-el7Server

With this patch b766bf7
we started tracking disks in attaching state so that other attach request can fail gracefully. However this missed the case where disks were in allocated state but attach was requested.
For the use case where users want to attach disk in allocated state but not ready, we need to have allocated-attaching transition as well. We must take care of returning to the original state - allocated or ready - when attach request has completed.
For the use case of unstarted vm's the disk must proceed as follows - "Allocated" -> Attaching -> Allocated. When VM is started, the disk is "created" and pool is assigned. For the use case of started VMs it's more trivial and disk proceeds as follows - Ready -> Attaching -> Ready.
Test this by creating a VM with "startvm=false", create a disk and try attaching it in allocated state. It would give an exception on latest 4.11 but will be fixed on this patch.

* 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!)
* formatting and cleanups
* fix imports that were wrongly changed during rebase
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
- remove custom <build> configuration in pom.xml

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.

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.
