[Feature]: Custom OS Icon & Category for Templates

[Dickboom]

Feature Description

Summary

Currently, the Templates page only supports a fixed set of OS categories and icons. Any non-standard OS (e.g. Anolis OS, openEuler, Rocky Linux, AlmaLinux, etc.) falls into the "Custom" bucket with a generic icon, making it hard to visually distinguish templates at a glance, especially when managing a large number of them.

This request covers two related improvements:

---

Problem / Use Case

Problem 1: No custom OS icon support

When a template is created from a non-mainstream distribution, ProxCenter displays a generic/default icon. There is no way to assign a custom icon to a template or override the auto-detected one.

Expected behavior: Users should be able to upload or specify a custom icon (e.g. PNG/SVG) for a template, which is then displayed in the template list and detail view.

---

Problem 2: Fixed OS category list — custom OSes all grouped under "Custom"

The Templates page groups templates by OS category using a hardcoded list. Any OS not in that list is lumped into a single "Custom" category, which becomes cluttered and unhelpful when you have multiple different custom distributions.

Expected behavior: Users should be able to define their own OS categories (e.g. "Anolis OS", "openEuler", "Internal Build") and assign templates to them. These custom categories should appear alongside the built-in ones in the category filter/sidebar.

---

Use Case

I use Anolis OS 8.9 (a RHEL-compatible distro maintained by Alibaba Cloud) as my primary OS template. It currently shows a generic icon and is grouped under "Custom" alongside unrelated templates. Being able to give it a proper icon and its own category would make the template library much easier to navigate.

Proposed Solution

Suggested Implementation

• Add an "Edit Template Metadata" action on each template card/row
• Allow setting:
  • Custom icon: file upload (PNG/SVG) or URL input
  • OS category: free-text input or select from existing + option to create new
• Custom categories should be persisted (in ProxCenter's own DB, not in Proxmox)
• The category filter on the Templates page should dynamically include user-defined categories
• Fallback to auto-detection if no custom value is set

Hi @Dickboom, thanks for the detailed write-up.

A couple of things up front, then one question so we scope this correctly.

On custom categories (Problem 2): In the Templates > Catalog view, the "category" you see is the image's vendor, and that field is already free text when you add or edit a custom image. If you set the vendor to Anolis OS, it gets its own filter chip alongside the built-in ones, so you are not limited to the fixed list there. The genuine gap today is the icon: a custom vendor currently falls back to a generic image icon, with no way to upload or point to your own. So Problem 1 (custom icon) is the real missing piece for catalog images, while Problem 2 is largely already possible for them.

One clarification we need: ProxCenter has two different "template" surfaces, and they behave very differently:

1. Templates > Catalog — cloud images you add and manage inside ProxCenter (stored in ProxCenter's own database). This is where the free-text vendor/category above applies, and where a custom-icon field would be a natural addition.
2. VM templates on your Proxmox nodes — guests you converted to templates, shown in the Inventory. These are read live from Proxmox; ProxCenter keeps no per-template metadata for them today, so there is currently nowhere to attach a custom icon or category.

Your Anolis OS 8.9 example ("my primary OS template") sounds like case 2, a VM template on your node, rather than a catalog cloud image. That distinction matters a lot for how we would implement this. Note too that Rocky Linux and AlmaLinux are already recognized in the catalog, so if you are seeing them under "Custom", that also points toward case 2.

Could you confirm:

• Which of the two surfaces you are looking at? A screenshot of where you see the generic icon / "Custom" grouping would be ideal.
• Your ProxCenter version?

That will let us scope the icon and category work accurately. Thanks!
