Summary
This blueprint proposes adding support to Nova for the use of VMware vSphere as a compute provider.
Requirements
R1. Support VMware vSphere as a compute provider within Nova. Deployment architecture is restricted to ESXi (i.e. ESX is not supported). VM storage is restricted to VMFS volumes on local drives. R2. Integrate with Glance, so that VM images can be streamed from there for boot on ESXi.
Assumptions
A1. The OpenStack project will not ship any VMware products or SDKs. Users will need to get the appropriate SDKs from VMware.
A2. The user will be responsible for configuring vSphere appropriately. Nova will not handle any automatic installation or configuration of the underlying hypervisor.
A3. The user will be responsible for configuring Nova with the details for each compute host. In particular, Nova will not interrogate vCenter to find compute hosts.
A4. Hosts managed by Nova will not be concurrently managed by vCenter agents or other third party. This would greatly increase the QA requirements.
A5. Hosts managed by Nova will not be subject to VMware Update Manager dynamic updates. This would greatly increase the QA requirements.
Rationale
Regarding R1's restriction to ESXi: On http://www.vmware.com/products/vsphere/esxi-and-esx/overview.html, VMware state "vSphere 4.1 and its subsequent update and patch releases are the last releases to include both ESX and ESXi hypervisor architectures. Future major releases of VMware vSphere will include only the VMware ESXi architecture. For this reason, VMware recommends that deployments of vSphere 4.x utilize the ESXi hypervisor architecture."
Design
Future
Release Note
Nova may now use VMware vSphere as a compute provider.
Discussion
Question: Does anyone want support for older versions or architectures of vSphere? Given that VMware are deprecating the ESX model in favour of ESXi, this blueprint currently proposes that we support only ESXi.
