The overview

What KVM is for

This web-based control plane offers browser-first provisioning and lifecycle management for KVM-powered virtual machines. It enables engineers to deploy, configure, and monitor isolated Linux guest environments directly from a web interface, abstracting underlying hypervisor commands for efficient infrastructure operations.

Who it helps

Useful ways to use KVM

01
Rapid Development Environment Provisioning
Quickly spin up isolated Linux VMs for testing new code, replicating production issues, or experimenting with different distributions without local hypervisor setup
02
Production VM Fleet Management
Oversee and manage a fleet of -backed production servers, perform routine maintenance, initiate live migrations for host upgrades, and monitor resource health across the infrastructure
03
Scalable Infrastructure Deployment
Deploy and scale virtualized infrastructure for applications and services with granular control over guest resources, optimizing costs and performance without significant upfront hardware investment

A practical path

How to use KVM

Provision a New Instance

Navigate to the 'Instances' section in the web portal, click 'Create New VM', and select your desired OS image (e.g., Ubuntu Server, CentOS Stream) and resource allocation (vCPUs, RAM, disk size)

Quick answers

Frequently asked questions

1What KVM features are exposed via the web interface?⌄

The web interface provides access to core KVM capabilities including VM creation, deletion, start/stop/reboot, snapshot management, live migration (if host supports), virtual network configuration, and storage volume attachment. Advanced `virsh` commands or direct QEMU parameters are typically abstracted or exposed through specific UI elements.

2Can I upload my own custom OS images or ISOs?⌄

Yes, the platform includes an 'Image Library' where you can upload custom ISO files or pre-built QCOW2 images. These can then be used as installation media or base images for new KVM instances.

3How is network isolation handled for KVM guests?⌄

Each KVM instance is provisioned with virtual network interfaces connected to isolated virtual networks or VLANs, configurable through the web portal. This ensures tenant separation and allows for custom firewall rules and routing within your virtual infrastructure.

4What is the pricing model for KVM instances?⌄

Pricing is typically based on a pay-as-you-go model, charged hourly for allocated vCPU, RAM, and storage resources. Data transfer and additional services like managed backups or dedicated IP addresses may incur separate charges. Specific rates are detailed on the 'Billing' page.

5Is API access available for programmatic VM management?⌄

Yes, a RESTful API is provided for full programmatic control over KVM instance provisioning, management, and monitoring. This allows for integration with CI/CD pipelines, infrastructure-as-code tools, and custom automation scripts.
