Everything for the ultix-streaming (VM 5111, pfv-tsys5) performance pass: full report + host audit results, staged/gated configs, guest prep + host one-shot + post-reboot-fix + netcheck lifecycle scripts, grow-root manual runbook, rolling tracking HUD, questions v1, and the gateway boot-race hardening units. Applied and verified live 2026-08-31; open work is tracked in Redmine project 55 as #601-#607. [#602] 💘 Generated with Crush Assisted-by: Crush:glm-5.2

Today: two commands, one reboot wave
1. On the VM (ultix-streaming, any time before step 2):
sudo ~/optimize/1-guest-prep.sh
Installs everything (kernel tunables, BBR, THP, cgroup slices, PSI collector, day/night timers, docker daemon.json, sddm autologin, no autolock). Docker restarts once. Touches NO storage.
2. From your desk (dry-run first if you like, then execute):
ssh root@pfv-tsys5.knel.net 'bash -s' < ~/optimize/2-host-one-shot.sh
ssh root@pfv-tsys5.knel.net 'bash -s -- --go' < ~/optimize/2-host-one-shot.sh
Graceful stop of 5111, ssd/discard/multiqueue/onboot flags, CPU priority over the sectestbed fleet, start 5111, then reboots every other running VM. No disk resizing, no host reboot (NFS role).
3. Say "done" here; I verify everything read-only and report.
Separate, whenever you choose (fully manual, step-by-step with checks):
root growth 279G -> ~505G via ~/optimize/GROW-ROOT-RUNBOOK.md. No script
runs it; no boot triggers it; you type every command yourself.
Rollback: apply-guest backs up every file it touches; qm flags are individually reversible.
Friday still owns: CPU/RAM swap (host power-off -> plan the NFS outage for -02 first), second USB3 card reseat, q35 + 20 vCPU / 128G reshape, GPUs.
