Simone aadab2d49b docs: Linux-guest benchmark (RUNBOOK §10) + Windows-host benchmark plan

§10: single-job Measure-CIBenchmark on LinuxBuild2404 (DHCP, 10 iter) on the
Linux host — boot total 8.82s avg, near-deterministic even on DHCP (IP-acquire
7.45s, σ≈0.01). Guest-vs-guest table: Linux guest ~63% faster boot total than
the Windows static-IP guest (§8) on the same host.

plans/benchmark-windows-host.md: dual-boot plan to collect the symmetric
Windows-host numbers (§11 Win static, §12 Linux DHCP, §13 concurrent burn-in)
so the host×guest×IP-mode matrix is complete and Linux-vs-Windows is a
column-for-column comparison. Includes Windows paths, Credential Manager
prereqs, and the BaseClean-Linux snapshot caveat.

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

Boot in Windows; verificare VMware Workstation + vmrun.exe in C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe.
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.
Credenziali in Windows Credential Manager (non keyring file): target BuildVMGuest (guest WinRM) e GiteaPAT (clone in-VM). Verifica: cmdkey /list | findstr /i "BuildVMGuest GiteaPAT".
Chiave SSH guest Linux presente: F:\CI\keys\ci_linux (per §12/§13 lato LinuxBuild2404).
Gitea raggiungibile (http://10.10.20.11:3100) e repo Simone/burnin-dummy con build.ps1 + build.sh (per §13).
F:\CI\BuildVMs\ privo di cloni orfani e F:\CI\ip-pool.json (se esiste) pulito — stesso caveat lease stale del Linux host (RUNBOOK §9 / TODO §2.8). Reset se serve: powershell Set-Content -Path 'F:\CI\ip-pool.json' -Value '{}' -NoNewline

3. §11 — WinBuild2025 static IP (pair §8)

.\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

10 iter completate, tabella per-fase stampata.
Confronto vs §8 (Linux host static): atteso clone/start simili, IP-acquire dominato da ci-static-ip.ps1 (~21.8 s floor, indipendente dall'host). Delta host atteso piccolo sulle fasi non-IP.

4. §12 — LinuxBuild2404 DHCP (pair §10)

.\scripts\Measure-CIBenchmark.ps1 `
  -TemplatePath 'F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx' `
  -SnapshotName BaseClean-Linux `
  -GuestOS Linux `
  -Iterations 10

10 iter completate.
Confronto vs §10 (Linux host, Lin guest DHCP, boot total 8.82 s): isola l'effetto host sul guest Linux. Se Win host ≫ 8.82 s, l'overhead è host-side (NTFS / NAT vmnet8 Windows), non guest.

5. §13 — Concurrent burn-in 4×10 (pair §9)

# 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'

Entrambi 40/40 PASS, 10/10 round.
Round avg vs §9 (Linux host: Win ~78.6 s, Lin ~70.2 s): delta = effetto host sotto concorrenza 4×.

6. Output e documentazione

Tutti i run appendono a F:\CI\Logs\benchmark.jsonl (single-job) e stampano summary (burn-in).
Copiare/annotare i risultati e aggiungere a docs/RUNBOOK.md le sezioni §11–§13 con le stesse tabelle di §8/§9/§10 e una riga finale di confronto host Linux-vs-Windows per ciascuna coppia.
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.
