[CLOUDSTACK-10454] GSoC Idea 2022 - Bypass Secondary Storage (Direct Download) on VMware &/or XenServer

• Type: New Feature
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

Background

The default way of registering / downloading templates in CloudStack involves caching them on the secondary store and then during VM deployment, the template is copied to the primary store. However, from ACS version 4.11.1 onward, a feature was added for KVM hypervisor to enable direct download to primary store. This massively reduces the usage of secondary store and also quickens the entire VM deployment process, as there is no need to copy the template from secondary to primary store. 

Requirement

We would like to propose an idea to extend this feature of direct download of templates onto primary store for other hypervisors - namely, VMware and XenServer. This would gravely benefit end-users to efficiently use the secondary storage and save overall time of VM deployment on the respective hypervisors

Relevant Skills:

Java
MySQL
Vue.js

Difficulty:

175 hours (Only VMware)
350 hours (VMware & XenServer)
