vdi epic status

This document records the dependency chain, current implementation state, and hardware/media gating status for the VDI epic (issue #69).

Status Summary​

The VDI epic is gated on hardware and media prerequisites (#129 and #132). The core Phase 1 desktop pool primitives (pkg/vdi and cmd/corral-vdi) and supporting platform adapters (pkg/snapshot, pkg/export, pkg/lifecycle, pkg/schedule, pkg/doctor) have landed and are fully covered by unit tests in CI.

Hardware & Media Blockers​

  1. GPU / Device Passthrough (#129):

    • Software-rendered desktops are a demonstration, not high-performance VDI.
    • Blocked on hosts with spare passthrough-capable devices; binding a GPU to vfio-pci on a workstation takes its physical display.
    • CI environment lacks dedicated GPU passthrough devices.

  2. Windows Guests (#132):

    • Blocked on non-redistributable Windows ISOs and virtio-win drivers (cannot be hosted in public CI repositories).
    • Long unattended installation cycles (30–60 minutes) per verification pass.

  3. Lifecycle at Pool Scale (#133):

    • Partially unblocked. pkg/lifecycle handles canonical InstanceRef power operations, and pkg/schedule manages windowed start/stop execution across contexts.

Landed Primitives & Adapters​

  • Phase 1 VDI Plugin (pkg/vdi, cmd/corral-vdi): Static pools, golden VM cloning via kubevirt.Client.Clone, label-based assignment (corral.dev/vdi-pool, corral.dev/vdi-assigned-to), and CLI lifecycle (pool create/list/delete, assign, unassign, connect).
  • In-Browser RDP Proxy: RDCleanPath proxy supporting IronRDP (ADR-0002 Phase 2).
  • Disk Snapshot Adapters (#134): Multi-backend snapshot/restore/retention in pkg/snapshot.
  • Export Adapters (#131): Per-backend disk image export in pkg/export.
  • Peer Diagnostics (#135): Multi-site reachability and console routing diagnostics in pkg/doctor.

Roadmap Recommendation​

Keep issue #69 tracked as an epic pending hardware/media resolution for #129 and #132. pkg/vdi remains active in the codebase for static pool creation and manual assignment.
