Security-conscious teams testing agent guardrails
Use a VPS when policies, permissions, logs, and runtime isolation need to be reviewed separately from daily local workstations.
How to Self-Host NemoClaw on a VPS
This guide explains how to self-host NemoClaw on a VPS so the runtime can live in a persistent remote environment instead of depending on a local machine. Virtarix provides the VPS infrastructure: NVMe storage, full root access, global locations, and an always-on server environment. You bring your own NemoClaw setup, provider access, API keys, repositories, tools, and configuration.
Who This Guide Is For
This page is for users who want NemoClaw-related experiments to run inside a narrow, controlled VPS boundary instead of a local workstation.
Operators who need isolated policy experiments
Keep guardrail tests, command permissions, OpenShell-related requirements, and rollback notes in a dedicated server environment.
Builders evaluating NemoClaw-related reference stacks
Use a disposable or tightly controlled VPS while comparing repository instructions, dependencies, and early-preview limitations.
Users who want a narrow VPS boundary for autonomous-agent tooling
Virtarix supplies self-managed VPS infrastructure; you install, configure, monitor, harden, and validate NemoClaw yourself.
What You Need Before You Start
Before selecting a plan or installing NemoClaw, confirm the server access, runtime path, credentials, firewall exposure, and recovery routine needed for the deployment.
A Linux VPS suitable for the current NemoClaw and OpenShell prerequisites; Ubuntu is the practical target for this guide.
SSH access to the server.
Root or sudo access.
Basic terminal knowledge.
Git and the package managers required by NemoClaw.
Docker installed and running before the NemoClaw installer. Installing Docker may require elevated privileges on Linux.
Node.js and npm as documented NemoClaw dependencies. The installer can install Node.js through nvm and NemoClaw through npm into user-local directories, but verify the active shell path before continuing.
Other runtimes only when your selected provider, tools, or repositories require them.
Your own API keys, provider accounts, model access, repositories, and configuration.
A domain name and firewall rules if you expose a web interface or webhook endpoint.
Backups or snapshots before production use or major upgrades.
Choose the NemoClaw Runtime Path
Before running commands, decide how NemoClaw should be installed, updated, restarted, and recovered on the VPS. Use current upstream documentation as the authority for exact versions and flags.
Recommended VPS Requirements
Minimum starting point for a NemoClaw test environment:
Recommended Architecture
The VPS is the runtime layer. You connect over SSH, configure NemoClaw, keep logs and runtime state on the server, and control API or model provider access yourself. For sizing context, return to NemoClaw VPS hosting before moving from test to production use.
User
Operator or developer controlling the workflow.
SSH
Secure access into the server.
Virtarix VPS
Runtime, storage, network, and package layer.
NemoClaw runtime
NemoClaw runtime layer for the workflow.
API/model provider
External model access and provider credentials.
Repositories, tools, and integrations
Code, automation tools, messaging gateways, and webhooks.
Step-by-Step Setup Flow
Follow this sequence as a practical deployment checklist, but confirm NemoClaw-specific versions, installer flags, and service commands against current official documentation before production use.
Prepare the VPS, connect over SSH, and create a clean workspace before installing NemoClaw, OpenShell, and Docker-related prerequisites.
ssh root@YOUR_SERVER_IPsudo apt update && sudo apt upgrade -yLog back in as the non-root deployment user before running the NemoClaw installer. Use root or sudo for server preparation and Docker setup, not for the user-local NemoClaw install itself. Configure Docker access after Docker is installed, then open a new login session before running the installer. Add the deployment user to the Docker group only when that user is trusted for broad host control, because Docker access can effectively bypass ordinary user separation.

It is a reference stack for running OpenClaw inside OpenShell, and its documented setup expects Docker plus Node.js/npm handling through the installer path. Use official NemoClaw documentation to confirm exact versions before relying on the server setup.
NVIDIA documents a guided installer that runs as a normal user, installs NemoClaw user-locally, onboards OpenClaw into an OpenShell-managed sandbox, and requires Docker to be installed, running, and reachable from that user session first.

Why NemoClaw Benefits from a VPS
NemoClaw is security-oriented, so the VPS should be treated as a controlled boundary for policies, logs, secrets, command permissions, and runtime experiments.
Isolated policy boundary
Use a VPS to keep guardrail experiments, allowed-command decisions, and OpenShell-related dependencies separate from personal machines.
Observable security-review logs
Keep run output, service logs, policy notes, and failed authentication evidence in one server-side location.
Controlled provider and network access
Track API keys, outbound network rules, firewall policy, and exposed service ports before adding real workloads.
Preview-stage discipline
Begin with the smallest possible access surface. Track policies, command permissions, network access, provider keys, logs, and rollback steps before adding real workloads.

Security Basics for NemoClaw on a VPS
Treat the NemoClaw server as a privileged runtime. Security should be part of the setup, not a later cleanup task.
Use SSH keys where possible.
Keep root login limited.
Use a non-root user where practical.
Restrict ports.
Store provider credentials, sandbox settings, and policy material only in the NemoClaw/OpenShell configuration paths documented for your selected setup.
Avoid committing real NemoClaw config, OpenShell policy files, provider keys, sandbox settings, or credential reset notes.
Review SSH access logs, Docker/OpenShell runtime logs, policy-file changes, guarded-action audit trails, provider-key usage, and outbound network rules.
Keep packages updated.
Snapshot before major NemoClaw changes.
Monitor failed login attempts.
Rotate exposed keys.
Keep experiments separate from production systems.
Document policy files, guardrail decisions, OpenShell-related requirements, allowed commands, and outbound network rules before real workloads are added.
Privileged runtime
The server can contain policy files, guardrail decisions, OpenShell-related requirements, allowed commands, outbound network rules, and security-review logs. Harden it before production use.
Troubleshooting
Common setup problems to check before blaming the VPS or framework.
Server firewall, wrong IP, or SSH service unavailable Confirm the VPS is running, check the IP, and verify port 22 or your configured SSH port.
Wrong key, wrong user, or disabled login method
Check ~/.ssh/authorized_keys, user permissions, and your SSH config.
Base packages or runtime packages were not installed Re-run the dependency step and compare runtime versions with official NemoClaw docs.
The selected NemoClaw path expects a different Node.js, Docker, or sandbox/runtime version Use the version manager or package source recommended by upstream docs.
Docker daemon stopped or not installed
Start Docker, confirm docker info works for the deployment user, and inspect NemoClaw/OpenShell logs.
Sandbox or gateway stopped after logout Use NemoClaw/OpenShell lifecycle commands and the documented sandbox runtime path rather than wrapping unknown host commands in a service manager.
A selected nemoclaw, openshell, sandbox, webhook, or supporting tool is bound to a port already used by another process
Run ss -tulpn and move one service to a different port.
A required nemoclaw, openshell, sandbox, webhook, or supporting tool port is not open Open only the required port and keep all other ports restricted.
Configuration is absent or incomplete Compare the generated configuration with the selected deployment path and add only the secrets and paths required.
Key is wrong, expired, or lacks access Rotate the key through the provider and update the server configuration.
Logs, caches, or repositories grew over time
Check df -h, rotate logs, clean caches, and scale storage if needed.
Too many sandbox processes, OpenShell components, Docker images, or background jobs Reduce concurrency, inspect process memory, and scale the VPS if the workload is valid.

FAQ
Can I run NemoClaw on a VPS?
Yes, if the NemoClaw release supports the Linux distribution and runtime path you choose. Use this guide together with the current official documentation.
Do I need a GPU VPS for NemoClaw?
Not for the VPS runtime pattern described here. This NemoClaw guide focuses on the NemoClaw/OpenShell sandbox, Docker runtime, provider access, policy files, guarded actions, and security-review logs; verify separate hardware needs if you plan local model inference.
Does Virtarix provide API keys or model access?
No. Bring your own provider accounts, credentials, API keys, model access, repositories, and framework configuration.
What VPS size should I use for NemoClaw?
Start NemoClaw with the recommended Virtarix Cloud VPS M for a practical first deployment, then scale after measuring CPU, RAM, storage, Docker image usage, sandbox processes, policy files, OpenShell requirements, guarded actions, and security-review logs.
Can NemoClaw keep running without my local machine?
Yes, when the NemoClaw/OpenShell sandbox is installed and managed through the documented server-side lifecycle. The VPS keeps policy files, OpenShell requirements, guarded actions, Docker state, and security-review logs separate from your local desktop session.
Can I use Docker for this setup?
Yes. For the documented NemoClaw installer path, Docker must be installed and running before onboarding. Treat Docker as part of the required NemoClaw/OpenShell stack unless the official documentation for your selected path says otherwise.
Is Virtarix operating NemoClaw for me?
No. Virtarix supplies self-managed VPS infrastructure. You install, configure, update, monitor, and secure NemoClaw yourself.
