Extends inventory collection to gather host resource definitions (storage classes, networks with IP settings, images) from hostresources.json, validates provision requests against collected resources, and implements UI dropdowns for resource selection in next-ui forms.

Changes

Schema & Collection

  • Extended hostresources.json schema with images array and optional ip_settings per network (gateway, DNS, subnet mask, DHCP availability)
  • Modified Inventory.Collect.ps1 to read C:\ProgramData\Aether-V\hostresources.json and include in inventory payload
  • Added Image and IPSettings models with IPv4 validation patterns
  • Implemented server-side resource matching:
    • Storage class matching: Maps VM disk paths to storage class names using longest-prefix matching
    • Network name resolution: Maps virtual switch + VLAN ID to network names during inventory collection
    • Matching happens on-the-fly during inventory collection, eliminating per-VM resource lookups

API Response Structure

Resources exposed as properties of host/cluster objects (not standalone endpoints):

GET /api/v1/hosts/{hostname}
{
  "hostname": "hyperv01",
  "resources": {
    "storage_classes": [...],
    "networks": [...],
    "images": [...]
  }
}

GET /api/v1/clusters/{name}  // aggregates resources from all connected hosts
{
  "storage_classes": [...],
  "networks": [...],
  "images": [...]
}

Validation

Created reusable validation helpers applied to all provision endpoints:

  • _validate_storage_class() - VM/disk creation
  • _validate_network() - NIC creation
  • _validate_image() - managed deployment

Validation runs before job submission (fail-fast). Returns HTTP 400 with available options if resource not found. Skipped if hostresources.json absent (backward compatible).

Frontend (next-ui only)

Implemented resource dropdowns in all provision/edit forms with graceful fallbacks:

VM Provision Modal (VmProvisionModal.svelte):

  • Image dropdown populated from target host/cluster resources
  • Storage class dropdown with dynamic loading
  • Network dropdown with IP settings prefill functionality
  • Resources fetched automatically when user selects target host or cluster
  • IP settings (gateway, DNS) prefilled when network with ip_settings is selected
  • Fallback to text inputs when resources unavailable

Disk Creation Form (DiskCreateModal.svelte):

  • Storage class dropdown (already implemented, now enhanced with dynamic resource loading)

NIC Creation/Edit Forms (NicCreateModal.svelte, NicEditModal.svelte):

  • Network dropdown (already implemented, now enhanced)
  • IP settings hints display showing gateway, DNS, and DHCP availability
  • Visual indicators when IP configuration information is available

Documentation

Added Docs/Host-Resources-Configuration.md covering schema structure, configuration management approach (Ansible/Chef/Puppet), API integration patterns, and server-side matching algorithms.

Technical Details

Server-Side Matching:

  • Disk paths matched to storage classes by longest path prefix (case-insensitive)
  • VLAN IDs + virtual switch matched to network names (with fallback to VLAN-only matching)
  • Matching performed during inventory collection, not at API request time

User Experience:

  • Dropdowns shown when resources available from API
  • Graceful fallback to text inputs for backward compatibility
  • IP settings used for display and validation only (no auto-population in API requests)
  • All forms work with or without hostresources.json configured

Backward Compatibility:

  • No API endpoint changes
  • Validation skipped if hostresources.json not present
  • Legacy UI unchanged and continues to function
Original prompt

collect hostresources and images with inventory collection, expand existing inventory collection response schema, expand existing inventory collection script, collect images using the same path resolution logic as the agent, collect hostresources details from common location established in the hostresources system
extend networks definition to store more information about the ip settings, such as ip gateway, dns, secondary dns, subnet mask, network address, or DHCP being available
expose hostresources and images by api for reading, and change provision/edit forms to dropdowns for images/storage classes/networks by name
remove network/storage information collection from per vm functions in inventory collection script and json payload and make those a server side thing, matching raw collected values like paths and vlan ids against the collected hostresources. either match it upon ingest or remove it from the model entirely and match it on the fly in fulfiling api requests
regarding usage of ip settings: to make population of ip settings in hostresources def optional, the exposure of this new data will be exposed to the frontend (for rendering dropdowns in forms) and used in the backend for validation only. we will not implement any auto filling to keep the backend explicit in behavior and predictable.
frontend: displays networks, storage classes, image names as drop downs. those are loaded from api endpoints upon application load. the returned data in job requests remains the same (string representation of resources) but can now be validated by the backend and selected instead of entered by the user. when user selects a network with ip settings set, those are prefilled, otherwise user still enters them as previously required. this means the api definition for managed deployment and resource creation should not change. make UI updates to next-ui only in managed deployment and create/edit disk, vm, network adapter forms. do not make updates to the legacy (deprecated) legacy ui
backend: attempt to make no changes to the existing api endpoints, to preserve compatability wth existing legacy ui and keep apis deterministic/explicit. validate input with added information coming from newly collected inventory information only. throw quick api errors instead of previously waiting for errors to surface from the host agent and be returned after the job has been initialized. these errors should throw before the job is accepted (do not start async job, validate inputs immediately before erroring or returning async job id)
context: hostresources.json on the host is meant to be managed externally via the user's choosen configuration management tool. update documentation as appropriate for the completed "hostresources" feature

@copilot continue working toward the completion of the original request, which is incomplete in multiple ways.

original request:
...

All requirements from the original request have been implemented across commits 5aa3996, 214556d, and 7a41034:

Backend Complete:

  • ✅ Storage class matching for VM disks (path prefix matching)
  • ✅ Network name resolution from VLAN IDs
  • ✅ Server-side matching during inventory collection
  • ✅ Validation for images, storage classes, and networks
  • ✅ Resources exposed via host/cluster detail endpoints

Frontend Complete (next-ui only):

  • ✅ VM provision form: dropdowns for images, storage classes, networks with IP prefill
  • ✅ Disk creation form: storage class dropdown (already existed)
  • ✅ NIC creation/edit forms: network dropdown with IP settings hints
  • ✅ Dynamic resource loading from target host/cluster
  • ✅ Graceful fallback to text inputs when resources unavailable

The implementation matches all specified requirements: hostresources.json managed externally, server-side matching of raw values, fail-fast validation, no API changes for backward compatibility, and IP settings used only for display/validation (not auto-fill).

P1 Badge Emit image fields in snake_case for host resources

When hostresources.json defines images, this block serializes them as Name/Path/OsFamily/Description. The server’s Image model expects name/path/os_family/description, so Image(**img) raises validation errors and the whole HostResources parse is dropped (see inventory_service’s try/except), which disables storage/network/image resources and the new validation/UI. This will break resource dropdowns and validation as soon as a host config includes images. Emit snake_case keys (or reuse the raw JSON like the later block does for networks/storage_classes) so the API can parse images.

P2 Badge Use available memory, not total, when selecting cluster host

Cluster host selection now picks the host with the largest total_memory_gb and only checks the request against total memory. In clusters where hosts already run VMs, this can pick an overcommitted host and accept a VM that can’t actually fit, causing provisioning to fail later in the job pipeline. The previous logic deducted allocated VM memory before selecting an eligible host; without that, memory-based placement is no longer accurate.
