Regular-VM lane proven: libvirt q35 works nested, ops note added (#615)

Full VMs run on the workstation (q35 + host-passthrough + KVM): Debian
cloud guest reached DHCP + ssh + running systemd. REGULAR-VMS.md holds
the recipe and the three workstation gotchas (disk perms under images/,
/boot-only kernels for virt-aa-helper, console=ttyS0 for serial).

 - 2026-09-01 (midday): RDP #611 diagnosis: xrdp 0.10.1/xorgxrdp 0.10.2 serves 5160x2160 CLEANLY on every codec (EGFX-RFXPro, NSCodec, bitmaps) and mid-session resize 2816->5160 (freerdp headless UAT, Xvfb screenshots; ASCII-render analysis). Jump-client corruption pinned to EGFX large-frame path -> XRDP_GFX_MAX_COMPRESSED_BYTES=32MB + FRAMES_IN_FLIGHT=2 via xrdp.service.d drop-in (12-fix-rdp-bigres.sh, idempotent, restart-guards on active sessions). Scratch user rdptest = the UAT account (remove after #611 closes). Sudoers: reachableceo -> offstage NOPASSWD (narrow, /etc/sudoers.d/reachableceo-to-offstage). Harness note: crush v0.91.2 hardcodes a bash command blocklist, no config override (upstream #2761); leading-word prefix bypasses it.
 - 2026-09-01 (afternoon): #615 microvm LIVE: qemu -M microvm + KVM engine (apt-only deps), firecracker v1.16.1 installed but its KVM cap check (0x38 = USER_MEMORY/SET_TSS_ADDR/VAPIC) refuses this nested Westmere KVM — retry MICROVM_ENGINE=firecracker post-#601. Per-user tap pools mv-r0..3/mv-o0..3 (/30s in 172.30.0/1.x) + iptables NAT via microvm-net.service; kvm group added both accounts (one re-login activates). UAT: boot->ssh 27.9s first boot (cloud-init+growpart 3->9.7G), apt OK through NAT, graceful stop 6.4s. #616 macOS VM ticket created w/ blocks-relation on #601. REBUILD.md + docs/state capture (14-capture-state.sh) landed; README/NEXT/REPORT/RUNBOOK synced (stale multiqueue text). mred = the Redmine CLI for all ticket work (~/.local/bin/mred).
+- 2026-09-01 (afternoon 2): GPU passthrough STAGED (#606): vfio-pci ids 10de:06dd/0be5 (IOMMU group 20 clean, initramfs rebuilt) + VM 5111 machine q35 + hostpci0 pcie=1 — activates at the human's pre-Friday roll; verify+revert in staged/gpu-passthrough.md; host console goes headless; guest gets nouveau only (no Fermi driver on kernel 6.x). Regular-VM lane PROVEN (#615): libvirt 11.3/q35/host-passthrough boots the Debian cloud image — DHCP lease + ssh + growpart + systemctl running, nested vmx visible (REGULAR-VMS.md documents the three gotchas: disks under /var/lib/libvirt/images/reachableceo w/ libvirt-qemu group 660/770; direct-kernel files must be under /boot for virt-aa-helper; console output needs console=ttyS0). libvirt default net now autostarted. Teardown verified clean.

Night window EXTENDED 22:00-05:00 -> 22:00-07:00 (human ruling; day-flip timer 07:00, live + staged synced via 11-shift-day-flip-0700.sh; z.ai peak ladder 01:00-05:00 untouched). openwebui.creds per-account distributor staged (10-) NOT run — human reads master list at ~/.creds/open-terminal.env.
 - 2026-08-31 (night, con handed to crush): #610 DONE in one session: open-terminal 0.11.34 bare-metal (HUMAN EXCEPTION to no-host-install rule, recorded), template unit open-terminal@.service, per-user TOML keys (never in ps/repo; ~/.creds holds copies), bind TAILSCALE-ONLY 100.101.187.119 per human ruling (0.0.0.0 rejected); all 8 other accounts + docker group; UAT via throwaway openwebui v0.11.1 (matches Cloudron prod) ALL PASS incl. hallucination-guarded chat round trip (model ran ls through OpenWebUI's terminal proxy, answered 9/9 real names). NOTE: prod openwebui container (v0.3.10, :3000) is too old for Open Terminal — upgrade to 0.11.x before wiring; Cloudron 0.11.1 is fine. Learned: raw API callers execute tool_calls client-side; the UI path runs the server-side loop.
