Phase B is closed (checklist Passi 1–9 [x], benchmark matrix §6–§14 recorded). Move the two finished working docs into the dated archive: plans/PhaseB-user-checklist.md → plans/archived/2026-06-07/ plans/benchmark-windows-host.md → plans/archived/2026-06-07/ plans/ now holds only the forward-looking plans (idea-3 Phase C pwsh removal, idea-4 Phase D ESXi, ideas-overview). Fixed the live links that pointed at the moved/relocated files: idea-3 §4, idea-2 §8 (relative path), and ideas-overview (idea-1/idea-2 now under archived/, Phase A+B marked ✅).

# Plan — Windows-host benchmarks (comparable to Linux-host §6–§10)
|
||
|
||
> **Scopo**: la macchina è dual-boot (Windows ⇄ Linux, stesso hardware).
|
||
> Le baseline RUNBOOK §6–§10 sono quasi tutte sul **Linux host**. Questo
|
||
> plan raccoglie i numeri mancanti sul **Windows host** per chiudere la
|
||
> matrice host × guest × IP-mode e rendere il confronto Linux-vs-Windows
|
||
> completo e simmetrico.
|
||
>
|
||
> **Prerequisito**: riavviare la macchina nel boot entry **Windows**.
|
||
> Tutto gira su Windows PowerShell 5.1 o pwsh 7; usare la stessa
|
||
> `Measure-CIBenchmark.ps1` / `Test-CapacityBurnIn.ps1` del repo (sono
|
||
> cross-platform, i default path passano a `F:\CI\...` quando `$IsWindows`).

## 1. Cosa esiste già e cosa manca
|
||
|
||
| RUNBOOK § | Host | Guest | IP mode | Stato |
|
||
| --------- | ----- | -------------- | --------------------- | ------------ |
|
||
| §6 | Win | WinBuild2025 | DHCP | ✓ 2026-05-17 |
|
||
| §7 | Linux | WinBuild2025 | DHCP | ✓ |
|
||
| §8 | Linux | WinBuild2025 | static | ✓ |
|
||
| §9 | Linux | Win + Linux | burn-in (static pool) | ✓ |
|
||
| §10 | Linux | LinuxBuild2404 | DHCP | ✓ |
|
||
|
||
**Mancanti sul Windows host** (target di questo plan):
|
||
|
||
| Nuovo § | Host | Guest | IP mode | Pair-with |
|
||
| ------- | ---- | -------------- | ------------ | --------- |
|
||
| §11 | Win | WinBuild2025 | static | §8 |
|
||
| §12 | Win | LinuxBuild2404 | DHCP | §10 |
|
||
| §13 | Win | Win + Linux | burn-in 4×10 | §9 |
|
||
|
||
§6 copre già Win×Win×DHCP. Opzionale: ri-eseguirlo nella stessa sessione per
|
||
coerenza (stesso disco/fragmentazione del momento).
|
||
|
||
---
|
||
|
||
## 2. Prerequisiti sul Windows host
|
||
|
||
- [x] Boot in Windows; verificare VMware Workstation + `vmrun.exe` in
|
||
`C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe`.
|
||
- [x] Template fully powered-off con snapshot integri:
|
||
```powershell
|
||
& 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' -T ws listSnapshots 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx'
|
||
& 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' -T ws listSnapshots 'F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx'
|
||
```
|
||
Attesi: `BaseClean` e `BaseClean-Linux`. ✓ (anche `PostInstall` su Win)
|
||
- [x] Credenziali in **Windows Credential Manager** (non keyring file):
|
||
target `BuildVMGuest` (guest WinRM, user `ci_build`) e `GiteaPAT`
|
||
(user `Simone`). Verificato.
|
||
- [x] Chiave SSH guest Linux presente: `F:\CI\keys\ci_linux` (per §12/§13
|
||
lato LinuxBuild2404).
|
||
- [x] Gitea raggiungibile (`http://10.10.20.11:3100`, HTTP 200) e repo
|
||
`Simone/burnin-dummy` con `build.ps1` + `build.sh` (verificato via API).
|
||
- [x] `F:\CI\BuildVMs\` privo di cloni orfani e `F:\CI\ip-pool.json` assente
|
||
(pulito). Reset se serve:
|
||
```powershell
|
||
Set-Content -Path 'F:\CI\ip-pool.json' -Value '{}' -NoNewline
|
||
```
|
||
|
||

|
||
|
||
## 3. §11 — WinBuild2025 static IP (pair §8)
|
||
|
||
```powershell
|
||
.\scripts\Measure-CIBenchmark.ps1 `
|
||
-TemplatePath 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx' `
|
||
-SnapshotName BaseClean `
|
||
-StaticIP 192.168.79.200 -Netmask 255.255.255.0 `
|
||
-Iterations 10
|
||
```
|
||
- [x] 10 iter completate, tabella per-fase stampata. **Boot total avg 29.75 s.**
|
||
- [x] Confronto vs §8 (Linux host static): IP-floor confermato host-independent
|
||
(22.81 s vs 21.77 s, +5 %). Penalità host: clone +58 % (NTFS), Ready +4.7 s
|
||
(WinRM re-bind dopo NIC reconfig), destroy +82 % (bimodale), boot +24 %.
|
||
Vedi RUNBOOK §11. **Nota**: primo tentativo fallito (timeout 300 s/iter) —
|
||
template Windows privo dell'agent `ci-static-ip`; risolto copiando i
|
||
template dal Linux host (parità template).
|
||
|
||
## 4. §12 — LinuxBuild2404 DHCP (pair §10)
|
||
|
||
```powershell
|
||
.\scripts\Measure-CIBenchmark.ps1 `
|
||
-TemplatePath 'F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx' `
|
||
-SnapshotName BaseClean-Linux `
|
||
-GuestOS Linux `
|
||
-Iterations 10
|
||
```
|
||
- [x] 10 iter completate. **Boot total avg 13.51 s.**
|
||
- [x] Confronto vs §10 (Linux host, 8.82 s): **+53 %** host-side — clone +191 %
|
||
(NTFS), IP-acquire +52 % (NAT vmnet8 Windows + guestinfo). Guest Linux resta
|
||
deterministico (IP σ ≈ 0.05 s). Vedi RUNBOOK §12.
|
||
|
||
## 5. §13 — Concurrent burn-in 4×10 (pair §9)
|
||
|
||
```powershell
|
||
# WinBuild2025
|
||
.\scripts\Test-CapacityBurnIn.ps1 `
|
||
-Parallelism 4 -Rounds 10 `
|
||
-TemplatePath 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx' `
|
||
-RepoUrl 'http://10.10.20.11:3100/Simone/burnin-dummy.git' `
|
||
-CloneBaseDir 'F:\CI\BuildVMs\' `
|
||
-ArtifactBaseDir 'F:\CI\Artifacts\' `
|
||
-VmrunPath 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' `
|
||
-BuildCommand 'powershell -ExecutionPolicy Bypass -File .\build.ps1'
|
||
|
||
# LinuxBuild2404 (snapshot OBBLIGATORIO, default è BaseClean=Windows)
|
||
.\scripts\Test-CapacityBurnIn.ps1 `
|
||
-Parallelism 4 -Rounds 10 `
|
||
-TemplatePath 'F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx' `
|
||
-SnapshotName BaseClean-Linux `
|
||
-RepoUrl 'http://10.10.20.11:3100/Simone/burnin-dummy.git' `
|

-CloneBaseDir 'F:\CI\BuildVMs\' `
|
||
-ArtifactBaseDir 'F:\CI\Artifacts\' `
|
||
-VmrunPath 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' `
|
||
-GuestOS Linux `
|
||
-BuildCommand 'bash build.sh'
|
||
```
|
||
- [~] **Linux 40/40 PASS (10/10 round). Windows 36/40 (7/10 round).** I 4 fail
|
||
Windows = fault WinRM transitori (round 6–8: connect-timeout 5986 +
|
||
WSManFault "shell not found") sotto 4× concorrenza; auto-recuperati (slot IP
|
||
rilasciati, 0 cloni orfani, round 9–10 di nuovo puliti). Linux/SSH 0 fault.
|
||
- [x] Round avg vs §9 (Win ~78.6 s, Lin ~70.2 s): Windows host Win ~91.6 s
|
||
(round PASS) **+16 %** + instabilità WinRM; Lin 96.4 s **+37 %**.
|
||
Vedi RUNBOOK §13. **Pre-req scoperti**: (1) parità template, (2) prod venv
|
||
F:\CI\python\venv stale (pre-`ip_pool`) → reinstallato `pip install .`,
|
||
(3) `CI_VENV_PYTHON` da settare (bug shim `$IsWindows` su PS 5.1+StrictMode).
|
||
|
||
---
|
||
|
||
## 6. Output e documentazione
|
||
|
||
- Tutti i run appendono a `F:\CI\Logs\benchmark.jsonl` (single-job) e
|
||
stampano summary (burn-in).
|
||
- [x] Risultati aggiunti a `docs/RUNBOOK.md` §11–§13 (+ §14 matrice completa),
|
||
con confronto host Linux-vs-Windows per ciascuna coppia.
|
||
- [x] Pulizia post-run: `F:\CI\BuildVMs\` vuoto, artifact `burnin-*`
|
||
rimossi, `F:\CI\ip-pool.json` reset.
|
||

||
## 7. Matrice finale attesa (dopo questo plan)
|
||
|
||
| Host \ (Guest, mode) | Win/DHCP | Win/static | Lin/DHCP | burn-in 4×10 |
|
||
| -------------------- | -------- | ---------- | -------- | ------------ |
|
||
| **Linux** | §7 | §8 | §10 | §9 |
|
||
| **Windows** | §6 | §11 | §12 | §13 |
|
||
|
||
Confronto colonna-per-colonna = **effetto host** a guest+mode costanti.
|
||
Confronto riga-per-riga = **effetto guest/IP-mode** a host costante.
