Cloudmin turns a Linux server into your own cloud. Create and run virtual machines from your browser, on hardware you control. It runs inside Webmin on libvirt and QEMU/KVM, so every machine is a normal libvirt guest and nothing is locked in.

Install it on a fresh Rocky Linux, AlmaLinux, Debian or Ubuntu host. Pick a cloud image, fill in one form, and the machine boots. Snapshots, clones, backups and consoles are built in, along with statistics charts and notifications by email, chat or webhook.

Cloudmin GPL is free: one host, as many machines as you like. Cloudmin Pro adds SSH key management, setup scripts, cloud backups and image capture. Managing many hosts from one place is coming in Cloudmin Connect.

Run Virtualmin? Pick a Virtualmin template and the whole hosting stack installs inside the new machine.

Cloudmin Features

One place to create, run, protect and reach KVM virtual machines on a Linux host.

KVM virtual machines managed through libvirt, so your usual tools keep working
Verified cloud images for AlmaLinux, Rocky Linux, Debian, Ubuntu, Fedora and more, plus your own images and ISOs
Templates and resource plans that fill one creation form, including accounts, SSH keys and networking
Virtualmin templates that install a complete hosting stack inside a new guest
Snapshots and full clones with fresh identities, from stopped or running guests
Scheduled backups to local, SSH and S3 destinations, with verified restore and cloud storage in Pro
SSH terminals, serial consoles and a graphical console, all in your browser
NAT, routed and isolated networks, and guided host bridges with automatic rollback
Directory, NFS, LVM and LVM-thin storage pools with free-space checks before every disk operation
Live status, resource charts and alerts for the host and every guest
Delegate single machines to Webmin users, with separate grants for power, consoles and terminals
Risky work runs in isolated workers without root, and every long task is a recoverable job

Cloudmin does not build its own hypervisor. It uses the libvirt and QEMU packages your distribution already ships, and adds the jobs, permissions, images and consoles a host needs. Nothing locks you in. The standard tools keep working on the same machines.

Built for safety, speed and control

Cloudmin makes a single KVM host easy to run without hiding Linux from you. Cloudmin Connect will grow it into a multi-host platform on the same foundation.

A short path to a running guest

Install Cloudmin, pick an image and click Create. The installer sets up libvirt, a network, storage and firmware, and checks that the host is ready.

Built on libvirt, not around it

Cloudmin never builds raw QEMU command lines or scrapes virsh output. Libvirt stays the source of truth, so other tools and your own scripts see the same machines.

Safe by design

Creation, cloning, backups and restores run as jobs that survive an interruption. Downloads, disk inspection and consoles run without root, so a bad image cannot take the host with it.

Virtualmin inside every guest

Choose a Virtualmin GPL or Pro template. Cloudmin installs the hosting stack inside the new machine and opens its Webmin through the host, even behind NAT.

Open source core, unlimited guests

Cloudmin GPL manages one host with as many virtual machines as it can carry. Pro adds SSH key management, setup scripts, cloud backups and image capture, with tenancy to follow. Cloudmin Connect will bring many hosts together.

The same API for people and scripts

The web interface, the command line and remote clients use one JSON API with signed requests, Webmin permissions and audit logging. Automate Cloudmin the way you already automate Virtualmin.
