# nh3-svos: host for the NEW SVOS operating system (VM 111 on nh3-pve-2, NH3)
|
|
|
|
Built 2026-10-05 at svos-dev's request, relaying Prime ("stand up a dedicated VM for it on nh3-pve-2"). It runs the
|
|
new SVOS (repo `corviduo/svoperatingsystem`): a FastAPI/uvicorn kernel (SQLite WAL, synchronous FULL, one writer),
|
|
an interface connector, an optional voice adapter and a static phone/desktop UI.
|
|
**It is a separate instance.** The existing High Seat (`svos.service` on nh3-dev, `:8770`) and Miranda are NOT
|
|
migrated by this host.
|
|
|
|
**Ownership split:** infra-ops owns the VM, OS, access, backups and ingress. svos-dev owns the application: install,
|
|
configuration, enrollment and acceptance.
|
|
|
|
| | |
|
|
|---|---|
|
|
| Address | `10.100.50.43`, VLAN 50 (nh3-servers), static via cloud-init; `nh3-svos.nh3.internal` |
|
|
| Guest | VM **111** on **nh3-pve-2**, `onboot 1`, tag `svos` |
|
|
| Shape | 4 vCPU `x86-64-v3`, 8 GiB, 100 GB on `vmstore` (local NVMe LVM-thin, discard on). nh3-pve-2 had 47 GB RAM and 946 GB vmstore free at build |
|
|
| OS | Debian 13 genericcloud, Python 3.13 + venv, SQLite 3.46, systemd-timesyncd (synced), qemu-guest-agent |
|
|
| Identities | `vh` 1000 (operator keys + lkraven@nh3-dev, so svos-dev's session can ssh in; NOPASSWD sudo from cloud-init), `infra-ops` 850, **`svc-svos` 801** (nologin; the only writer of the data root) |
|
|
| Data root | `/var/lib/svos`, svc-svos 0700, on the local root ext4. Never NFS, never shared |
|
|
| Releases | `/opt/svos` root:svc-svos 2775, with `releases/` for svos-dev's layout. The git checkout is not a runtime dependency |
|
|
| Docker | none, by design |
|
|
| Backups | nh3-pve-2 vzdump job, nightly **21:30**, `all 1` → pbs-ana namespace `nh3-pve-2` (mirrored to pbs-nh3 at 06:30), snapshot mode with guest-agent fs-freeze |
|
|
| App-consistent hook | `/etc/qemu/fsfreeze-hook.d/` exists. The guest agent runs those scripts on vzdump's freeze/thaw, which is where svos-dev's SQLite checkpoint hook belongs. Until it lands, backups are crash-consistent (fine for WAL + synchronous FULL, but not the stated requirement) |
|
|
| Monitoring | not yet. Beszel needs the native agent here (no Docker); that is pending together with nh3-albok's |
|
|
|
|
## Build (reproducible)
|
|
|
|
```bash
|
|
scripts/elway infra-ops@10.100.250.62 --playbook playbooks/nh3-pve-2-cloudinit-vm.yaml --var vmid=111 \
|
|
--var name=nh3-svos --var ip=10.100.50.43/24 --var cores=4 --var memory=8192 --var disk=100G --var tags=svos \
|
|
--var "description=..."
|
|
scripts/elway vh@10.100.50.43 --playbook playbooks/bootstrap-infra-ops-user.yaml
|
|
scripts/elway infra-ops@10.100.50.43 --playbook playbooks/nh3-svos-host.yaml
|
|
```
|
|
|
|
## Ingress / auth: NOT built yet, proposal pending (Prime + svos-dev)
|
|
|
|
App listeners stay private (loopback or a Unix socket). The front door has to give the browser **HTTPS**: the UI and the
|
|
voice adapter need a secure context for the microphone. It also has to give the kernel's adapter a **verified identity**
|
|
in `Tailscale-User-Login`, with any browser-supplied copy stripped. See the svos-dev thread of 2026-10-05.
