Product & Deployment

Details on VPS specs, provisioning time, and featured services

Q01 Does KVMNODE provide virtual machines or real physical hardware?

Real hardware in the cloud, not a VM. KVMNODE gives you exclusive access to real physical hardware in the cloud β€” fundamentally different from VMs or containers that share resources.

Every device is delivered with full permissions, including complete root access and low-level hardware access. CPU, memory, and disk I/O are all truly dedicated β€” never shared with other users. You can freely install any OS and software, and run any workload.

Physical-level access means you can run Docker, K8s, custom kernel modules, low-level network configurations, and any application requiring full system capabilities β€” with no restrictions.
Q02 How soon can I access my instance after purchase?

We use afully automated provisioning workflow. After a successful payment, system initialization typically completes within 3–10 minutes, and SSH connection details are sent by email.

The console Instances page also updates in real time. If you have not received the email within 15 minutes, check your spam folder or contact support via ticket.

During peak periods (e.g., large-volume orders), provisioning may occasionally take longer β€” normally not exceeding 30 minutes.
Q03 Are resources oversold?

No overselling. CPU and memory resources are strictly allocated per the purchased plan, guaranteed as dedicated.

Disk I/O also has QoS protection. High-performance NVMe SSD with dedicated I/O quotas ensures stable service performance unaffected by neighboring instances.

If you suspect a performance anomaly, submit a benchmark result via ticket. We will investigate the host load within 2 hours.
Q04 Does KVMNODE support OS reinstallation or version changes?

Yes. Since you have full control of the device, you can reinstall the OS at any time. We support major Linux distributions including Ubuntu, Debian, and CentOS Stream, and you can also mount a custom image for installation.

If you need help with a specific minor version or encounter issues, submit a ticket and our engineers will typically respond within 1–2 hours.

OS reinstallation will wipe all data on the disk. This action is irreversible β€” please back up any important files beforehand.
Q05 Can I install any software and modify system configurations?

Yes. Your device is delivered withfull root access. You are free to install software, configure firewalls, and load kernel modules.

Docker, K8s, Nginx, MySQL, Python, Node.js, and other development and ops tools can all be installed quickly via the package manager. We do not restrict your workload type, as long as you comply with the Terms of Service (no illegal activity or malicious attacks).

Network & Nodes

Questions about bandwidth, IP, latency, and data centers

3 Articles
Q01 Are bandwidth and IP dedicated?

Fully dedicated. Each VPS is allocated 1Gbps dedicated uplink bandwidth with unmetered traffic (within the fair use policy).

Each VPS also comes with a dedicated public IPv4 address β€” no port restrictions or spam blacklist risks from shared IPs. Ideal for directly exposing web services or building a private API.

If you need additional IPv4 addresses, contact us via ticket. Extra IPs can be provisioned on demand (billed monthly).
Q02 Which data center regions are available?

KVMNODE operates its own nodes at core hubs across Asia-Pacific and North America, covering 6 regions:

  • πŸ‡ΈπŸ‡¬
    Singapore
    ~40ms
  • πŸ‡―πŸ‡΅
    Japan β€” Tokyo
    ~35ms
  • πŸ‡°πŸ‡·
    South Korea β€” Seoul
    ~45ms
  • πŸ‡­πŸ‡°
    Hong Kong, China
    ~8ms
  • πŸ‡ΊπŸ‡Έ
    US West (Silicon Valley)
    ~120ms
  • πŸ‡ΊπŸ‡Έ
    US East (Virginia)
    ~150ms

Latency figures above are reference values measured from major cities in mainland China. Actual latency varies by network environment.

Q04 Is DDoS protection available?

Our data center infrastructure providesbaseline DDoS protection against common volumetric attacks. All inbound traffic is filtered at the network layer before reaching your VPS.

If your business requires enterprise-grade DDoS protection (scrubbing centers, high-protection IPs, etc.), we recommend layering Cloudflare or another CDN service on top β€” fully compatible with the KVMNODE VPS.

Remote Access & Management

SSH, VNC connection, and server management operations

5 Articles
Q01 How do I connect to my VPS via SSH?

After your VPS is provisioned, you will receive the IP address and initial SSH password in both the console and by email. Connect using any terminal tool:

# Basic SSH connection command
ssh root@<Your VPS IP> -p 22

On first connection, enter yes to confirm the host fingerprint, then paste the initial password. It is strongly recommended to configure SSH public key authentication and disable password login after the first login:

# Upload your local public key to the server
ssh-copy-id root@<Your VPS IP>
Q02 How do I access a graphical interface via VNC?

The console provides a browser-based Web VNC β€” no client installation required. Click "Open VNC" in the Instance Details section to access the graphical interface directly.

You can also connect using a native VNC client (e.g., RealVNC Viewer, TightVNC). The address and port are available on the Instance Details page in the console.

VNC graphical interface is best suited for diagnosing SSH login failures, system boot issues, and similar scenarios. For routine management, SSH is recommended.
Q03 How do I restart or shut down my VPS?

There are two ways to manage the power state of your VPS:

  1. In-system command (recommended): After logging in via SSH, run:
    reboot # Restart
    shutdown -h now # Shutdown
  2. Console operation: Log in to the KVMNODE console β†’ Instance Details β†’ click [Restart] or [Force Shutdown]. This is a hard reset β€” prefer in-system commands when possible.
Q04 How do I change the SSH password or port?

After logging in via SSH, you can freely change the password and port configuration:

# Change the current user password
passwd
# Change the SSH port (edit sshd_config)
nano /etc/ssh/sshd_config
# Find Port 22 and change it to your custom port, e.g. Port 2222
systemctl restart sshd
After changing the port, test the connection in a new terminal window before closing the old one β€” to avoid locking yourself out.
Q05 How do I check the hardware specs of my VPS?

There are two ways to view the full configuration specs:

  1. Console: Log in to the KVMNODE console β†’ Instance Details. The dashboard page shows a summary of CPU, memory, storage, IP, and other specs.
  2. Command line: Run the following commands via SSH:
# View CPU information
lscpu
# View memory usage
free -h
# View disk information
df -h

Billing & Support

Order status, renewal, refunds, and customer support

4 Articles
Q01 How do I check order status, expiry dates, and renewal history?

After logging in to the console, select "Billing" from the left navigation to view all transaction history and order details.

The instance list prominently displays the "Next Expiry Date". Weekly/monthly/quarterly subscriptions auto-generate a renewal invoice before expiry. To cancel, click [Do Not Renew] before the expiry date.

Daily purchases are one-time charges that expire automatically β€” no auto-renewal and no manual cancellation needed.
Q02 Can I get a refund if I cancel early?

We offer the following refund policy:

  • 24-hour no-questions-asked refund: If provisioning fails or the instance is unreachable due to our fault within 24 hours of activation, a full refund is available.
  • Pro-rated refund: For voluntary cancellation during a subscription, a refund is issued proportional to the remaining days (minus days used and a 5% processing fee).
  • Non-refundable: Daily billing orders are non-refundable after payment.

All refund requests must be submitted via the ticket system. Include "Refund Request - Order #" in the ticket title.

Q03 What payment methods are supported?

The following payment methods are currently supported. Available options are loaded in real time on the order page:

  • Credit card: Visa and Mastercard supported (processed via Stripe).
  • Cryptocurrency: Bitcoin, USDT, and other major cryptocurrencies supported.
All payments are processed through secure channels. We do not store your full payment card details.
Q04 How do I contact customer support?

We offer 24/7 ticket support with a guaranteed 24-hour first response.

Log in to the console β†’ "Tickets" β†’ "New Ticket" and select the appropriate category (Technical Issue / Billing / Sales Inquiry).

You can also email us directly at:[email protected]
