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.

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.

Consider this scenario:
1. User launches a VM from Template and keep it running
2. Admin logins and deleted that template [CloudPlatform does not check existing / running VM etc. while the deletion is done]
3. User resets the VM
4. CloudPlatform fails to star the VM as it cannot find the corresponding template.
It throws error as
java.lang.RuntimeException: Job failed due to exception Resource [Host:11] is unreachable: Host 11: Unable to start instance due to can't find ready template: 209 for data center 1
at com.cloud.vm.VmWorkJobDispatcher.runJob(VmWorkJobDispatcher.java:113)
at org.apache.cloudstack.framework.jobs.impl.AsyncJobManagerImpl$5.runInContext(AsyncJobManagerImpl.java:495)
Client is requesting better handing of this scenario. We need to check existing / running VM's when the template is deleted and warn admin about the possible issue that may occur.
REPRO STEPS
==================
1. Launches a VM from Template and keep it running
2. Now delete that template
3. Reset the VM
4. CloudPlatform fails to star the VM as it cannot find the corresponding template.
EXPECTED BEHAVIOR
==================
Cloud platform should throw some warning message while the template is deleted if that template is being used by existing / running VM's
ACTUAL BEHAVIOR
==================
Cloud platform does not throw as waring etc.
This closes#1644
* 4.9:
CLOUDSTACK-4858 Honors the snapshot.backup.rightafter configuration variable Unhides snapshot.backup.rightafter from global configuration
Unhides snapshot.backup.rightafter from global configuration
If snapshot.backup.rightafter is set to false (defaults to true), snapshots are
not backed up to secondary storage
The behavior is now consistent with template creation. This commit
also adds a unit test for this functionality to make sure that it will
always happen.
These tests validate that the templates get scheduled for seeding. Additionally,
if a template is already seeded, we do not try and seed it again. Tests also
validate that templates are seeded to storage pools which are available.
