Following use cases mentioned in the FS is not supported (according to the comments in https://issues.apache.org/jira/browse/CLOUDSTACK-684 ): * Admin can place a limit on the number of stored snapshots per user * Users can create snapshots manually or by setting up automatic recurring snapshot policies** Snapshots can be created on an hourly, daily, weekly, or monthly interval. One snapshot policy can be set up per VM * With each snapshot schedule, users can also specify the number of scheduled snapshots to be retained** Older snapshots that exceed the retention limit are automatically deleted. * This user-defined limit must be equal to or lower than the global limit set by the CloudStack administrator. * The limit applies only to those snapshots that are taken as part of an automatic recurring snapshot policy. Additional manual snapshots can be created and retained Can the FS be updated to reflect this? [mice] already added in the limitation section 2. Supported Hypervisor: Could you confirm the list of hypervisors that will be supported for this feature? From the discussions in the email thread , I see that KVM implementation has dependencies on libvirt-java and for Xenserver there is dependency on volume snapshot design being improved. Because of the above restrictions , Can you confirm that Vmware will the only hypervisor that is supported? [mice] For current master branch, VMware and Xenserver are supported. KVM support depends on un-released libvirt-java. 3. Is there a known limit on the number of snapshots that can be created for a VM specific to each hypervisor ? [mice] for Vmware/Xenserver, the official max snapshot chain is 32 4. VM Snapshot List - Support query by keyword . Can you elaborate on how we can set a keyword for a VM Snapshot? listVMSnapshot() does not have a parameter for this . [mice] Sorry FS is outdated, query by keyword has not been implemented because from my point of view, this use case is not so obviously demanded (query by vm_id is the most common use case) I will update the FS and if there are some request for query by keyword, it will be implemented later. 5. Database Schema for vm_snapshots does not list vm_id. Vm_id should be part of the vm_snapshots table , correct ? [mice] vm_id is already a column of table vm_snapshots (FS is a bit outdated). Please re-check it in database. -Thanks Sangeetha
