mike-tutkowski opened a new pull request #2298: CLOUDSTACK-9620: Enhancements for managed storage
URL: https://github.com/apache/cloudstack/pull/2298
 
 
   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
