VM Settings

This page provides detailed controls and settings for managing a Virtual Machine (VM).

The VM Settings tab offers full control over your VM environment, including storage, networking, OS, firewall, and more.

VM Settings Tab Overview​

The left-hand sidebar contains key configuration options:

  • Block Storage (Volumes): Manage attached volumes and create snapshots
  • Change Plan: Upgrade or customize your VM specs (downgrades not supported)
  • Change Hostname: Rename the VM; this triggers a reboot
  • Change OS: Reinstall the operating system (this erases all data)
  • Reset Password: Regain access by resetting the root/admin password
  • Change Startup Script: Automate tasks that run on boot
  • Firewall: Configure inbound/outbound rules
  • Networks: Manage public/private network settings
  • Port Forwarding: Forward traffic to internal services
  • SSH Keys: Add/manage keys for password-less access

Block Storage (Volumes)​

Manage attached volumes, view current storage, and create or delete snapshots.

tip

This section helps monitor disk allocation and manage backups.

Change Plan​

Upgrade your VM by selecting a predefined plan or customizing one.

warning

Downgrading a plan or reducing disk size is not supported and may risk data loss.

Choose from:

  • Standard configurations
  • Custom plans with CPU/RAM/storage tailored to your needs

Change Hostname​

Modify the hostname your VM uses on the OS and network level.

info

Changing the hostname will reboot your instance.

Change OS​

Reinstall or change the operating system.

danger

Changing the OS will erase all current data.
Ensure you’ve taken snapshots or backups before continuing.

Reset Password​

Use this to reset your root/admin password if you've lost access.

  • The instance will reboot
  • New credentials will be set after the reboot completes
tip

Useful in case of login failure or expired credentials

Change Startup Script​

Set or edit a script that executes every time the VM starts.

  • Automate provisioning
  • Set custom environment variables
  • Install software on boot

Firewall​

Control which ports and protocols are allowed to reach your VM:

  • Allow only trusted traffic
  • Protect against unauthorized access
  • Define rules by IP, protocol, and port

Networks​

Configure public and private networks:

  • Assign or release public IPs
  • Switch between isolated or VPC-style networking
  • Adjust DNS or gateway configs

Port Forwarding​

Expose internal services by forwarding ports:

  • Host web servers, APIs, databases
  • Public Port → VM Internal Port
  • Custom NAT rules

SSH Keys​

Manage SSH keys that allow secure access to your VM:

  • Add new keys
  • Revoke old or unused ones
  • Secure remote login without using a password

Conclusion​

The VM Settings tab is your hub for full virtual machine control.
From storage to network, from security to automation — you can fine-tune every detail of your VM to fit your project’s needs.
