A Virtualizor license lets you turn your own physical server into a platform for creating and selling virtual private servers, managed from a web panel instead of the command line. Virtualizor, made by Softaculous, handles creating VPSs from ready-made operating system templates, resource limits, IP allocation, statistics and an end-user panel for each customer. Tremhost sells Virtualizor licences for $3 a month or $34 a year.
What Virtualizor does
Without a panel, every VPS on a host server is built and maintained by hand: allocating disk and memory, attaching IP addresses, installing an operating system and giving the customer a way to reboot or reinstall. Virtualizor puts all of that into two web interfaces:
- An admin panel where you add host servers (nodes), define plans with CPU, RAM, storage and bandwidth limits, manage IP pools and create, suspend or delete VPSs.
- An end-user panel where each customer can start, stop and reboot their VPS, reinstall the operating system from a template, open a console and view usage graphs.
It also includes ready-made Linux and Windows templates, so a new VPS is deployed from an image rather than installed from an ISO, and real-time statistics for each node and each virtual machine.
Supported virtualisation
Virtualizor works with several virtualisation technologies, including KVM, Xen, OpenVZ, LXC, Virtuozzo and Proxmox. For most new deployments, KVM is the common choice because each VPS runs its own kernel, which lets customers run Docker and any Linux distribution or Windows. Container technologies such as LXC and OpenVZ are lighter but share the host kernel, which limits what customers can change.
Who needs a Virtualizor licence
- Hosting companies selling VPS who want an automated panel for customers.
- Agencies and developers splitting one large dedicated server into separate machines for staging, production and client projects.
- Organisations that want to give departments their own servers on shared hardware, with clear resource limits.
If you only need one VPS, you do not need Virtualizor: rent a VPS directly. The panel is for people who own or rent the physical server and want to divide it.
Features that matter when you sell VPS
Plans and resource limits
Create plans such as 2 cores, 4 GB RAM and 60 GB storage, then deploy VPSs from them in a few clicks. Limits stop one customer from consuming the whole node.
IP management
Define IPv4 and IPv6 pools and Virtualizor assigns addresses automatically when a VPS is created.
Billing and automation
Virtualizor includes its own billing module with hourly charging, and integrates with WHMCS, so orders can create, suspend and terminate VPSs automatically. An API lets you connect your own systems.
Backups and high availability
You can schedule VPS backups to local or remote storage. On supported setups, high-availability clustering can restart virtual machines on another node if one host fails, which removes a single point of failure.
What you need before you install
- A dedicated server with hardware virtualisation support enabled in the BIOS, and enough RAM and storage for the VPSs you plan to host.
- A clean supported Linux installation. Check Virtualizor’s documentation for the current list of supported host operating systems for your chosen virtualisation type.
- Additional IP addresses for your VPSs, routed to the server by your provider.
- Storage planned in advance, such as LVM or file-based storage, because changing it later is disruptive.
- The licence, tied to the server’s main IP address.
If you need hardware, Tremhost’s dedicated servers are configured to your specification. Ask the team for a clean operating system and the extra IP addresses you need before you plan a VPS business on one.
Planning capacity on a node
Decide how far you will divide each server before you sell the first VPS. Keep some memory and CPU for the host itself and for Virtualizor. Be cautious about overselling RAM: if every customer uses their full allocation at once, the node starts swapping and every VPS slows down. Disk space is easier to monitor but fills faster than expected once backups and snapshots are counted. Start with conservative plans, watch the node statistics for a few weeks, and adjust. It is easier to add capacity than to explain to customers why their servers are slow.

Frequently asked questions
Is Virtualizor a hypervisor?
No. It is a management panel. The hypervisor, such as KVM, does the virtualisation; Virtualizor controls it.
Can customers reinstall their own operating system?
Yes. The end-user panel lets them reinstall from the templates you make available.
Can I run cPanel inside a Virtualizor VPS?
Yes. Each VPS is a separate server, so it can run cPanel with its own VPS licence.
Do I need Virtualizor on a Tremhost VPS?
No. Tremhost VPS plans already come with their own VPS panel. Virtualizor is for your own physical servers.
What happens if the licence lapses?
Existing virtual machines generally keep running, but you lose access to the panel until you renew, so renew on time.
