1. 🔎 Introduction
Virtual Machine images are the foundation of a scalable cloud platform. With the right templates, administrators can provision consistent environments in seconds—accelerating development, reducing errors, and maintaining compliance.
XAVS simplifies image lifecycle management by supporting:
- Pre-configured VM templates for rapid reuse
- A centralized image catalog for teams and departments
- Compatibility with major formats like
qcow2,vmdk, andraw - Safe export for backup or multi-region replication
Whether you're deploying one VM or hundreds, XAVS Image Management helps standardize and accelerate infrastructure provisioning.
2. 🧱 Architecture Overview
🔹 Image Management Components in XAVS
| Component | Role |
|---|---|
| Image Backend | Stores and serves VM images in supported formats (qcow2, etc.) |
| Catalog Layer | Organizes images with metadata, tags, and access control |
| CLI/API Tools | Enables importing, exporting, and configuring images |
| Automation Tools | Integrate with Packer/Terraform for CI-based image pipelines |
🧩 These components allow you to manage golden images, stack templates, and base OS media efficiently across your XAVS environments.
3. ✨ Key Features
-
🧱 Reusable Templates
- Create and reuse pre-installed base images for common use cases
-
📚 Enterprise Image Catalog
- Organize and tag images for departments or teams (e.g., Dev, QA, Prod)
-
🧩 Multi-Format Support
- Use images built from VMware, Packer, or ISO media
-
🔄 Export & Import
- Backup or replicate images across regions or deployments
-
⚙️ Automation Ready
- Integrate with image builders and IaC tools for consistent pipelines
4. 🧰 Use Cases
| Use Case | Description |
|---|---|
| DevOps Templates | Pre-installed images with Docker, Git, and CI agents |
| Internal Catalogs | Maintain versioned app stacks for different environments |
| Multi-Tenant Environments | Tag and restrict access to images per department or tenant |
| Backup & Portability | Export images for DR or cross-region migration |
5. 🔗 Example Templates & Commands
🔹 A. Creating a Template from an Existing VM
openstack server image create --name mern-template <VM_ID>Creates a reusable image of the running instance after configuration and cleanup.
🔹 B. Organizing the Image Catalog
openstack image set --property app_stack=mern mern-template
openstack image set --tag devops mern-templateAdd searchable metadata and tags to structure your internal image catalog.
🔹 C. Importing Custom Images
openstack image create \
--disk-format qcow2 \
--container-format bare \
--file ./custom-mern.qcow2 \
--public mern-templateSupports importing from image builders like Packer or conversion tools from VMware.
🔹 D. Exporting & Saving Images
openstack image save --file ubuntu-22.04.qcow2 ubuntu-22.04Useful for creating external backups, transferring across regions, or archival.
6. 🤖 Automation and Operational Fit
-
CI/CD with Packer
- Automate daily/weekly image builds from Git-controlled templates
-
Terraform Integration
- Refer to image IDs during VM provisioning with IaC consistency
-
Versioning & Metadata
- Track template versions via properties (e.g.,
build_version=1.3.2)
- Track template versions via properties (e.g.,
-
Multi-Region Replication
- Export/import workflows enable syncing image catalogs across XAVS zones
