Virtualizor is a web-based VPS control panel from Softaculous. Hosting providers use it to create and manage virtual private servers on their own hardware, while customers use its end-user panel to control their VPS. This guide explains how Virtualizor works before you install or use it.
Before you start
- Basic knowledge of how a VPS works.
- Check the official Virtualizor site for current licence pricing and supported OS versions.
Master and slave architecture
- Master server: runs the admin panel, database and API. It can also host VPSs itself.
- Slave servers: additional hypervisor nodes registered with the master. The master sends them commands to create, start, stop or rebuild VPSs.
- Servers can be grouped (for example by location) so plans place VPSs on the right nodes.
Set up guides: install the master and add a slave node.
Supported virtualization
Virtualizor's main platform is KVM, and it also supports container technologies such as OpenVZ and LXC, plus some other hypervisors depending on version. Each server is installed for one virtualization type. See KVM vs OpenVZ vs LXC.
Admin panel features
- Plans: CPU, RAM, disk, bandwidth, network speed and IP counts.
- IP pools: IPv4 and IPv6 ranges assigned automatically, with reverse DNS support.
- Storage: file, LVM, LVM-thin, ZFS and other storage types per server.
- OS templates and ISOs: ready templates plus custom ISO uploads.
- Backups: scheduled VPS backups to local or remote destinations.
- Users and resellers: admin ACLs and reseller limits.
End-user panel features
- Start, stop, restart and power off.
- VNC or noVNC console, rescue mode and OS reinstall.
- Root password and hostname changes, rDNS, firewall rules, bandwidth graphs.
- API access for automation.

Billing automation
Virtualizor integrates with WHMCS and other billing systems through modules: when a customer pays, the VPS is created automatically, and it is suspended or terminated on non-payment. See sell VPS with WHMCS and Virtualizor.
