>                 Key: CLOUDSTACK-9620
>                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9620
>             Project: CloudStack
>          Issue Type: Improvement
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: KVM, Management Server, VMware, XenServer
>    Affects Versions: 4.11.0.0
>         Environment: KVM, vSphere, and XenServer
>            Reporter: Mike Tutkowski
>            Assignee: Mike Tutkowski
>             Fix For: 4.11.0.0
>
>
> 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
> Enable cluster-scoped managed storage
> Add support for VMware dynamic discovery
