LXD vs Virtualizor

LXD is an open-source platform for managing system containers and virtual machines on Linux. It brings LXC-based containers and KVM-based virtual machines together, with images for many Linux distributions and Windows virtual machines. Management options include a command line, REST API, web UI and third-party tools; the same HTTP API supports local and remote access. An official web UI is available by default starting with LXD 5.21.0 LTS. Features include resource limits, scheduled and expiring snapshots, projects, hardware passthrough, live migration and advanced networking. Containers run unprivileged by default, and virtual machines support UEFI Secure Boot and vTPM. LXD can run from a laptop to a data-center deployment; documentation describes clusters of up to 50 servers with thousands of instances. LXD is free, with the open-source plan listed at free. Ubuntu Pro Personal is also free for up to five physical Ubuntu systems. Enterprise workstation and server subscriptions are $25 a year and $500 a year, respectively.

Virtualizor is a self-hosted, web-based control panel for hosting providers running VPS and cloud infrastructure. It connects operators, customers, and hypervisors on server nodes, with API access for provisioning and management workflows. Supported hypervisors include OpenVZ, OpenVZ 7, Xen PV, Xen HVM, XenServer, Linux KVM, LXC, Proxmox, and Virtuozzo; Docker and bare-metal management are also described. Administrators can create, start, stop, rebuild, clone, and migrate virtual machines. Browser-accessible noVNC and VNC consoles are provided, alongside RDP and serial console access. Templates cover Linux, Windows, and Webuzo systems. Integrations include WHMCS, Blesta, HostBill, and ClientExec modules, plus PHP and Python SDKs. Security controls include login limits, bans, LDAP, two-factor authentication, and IP allowlists. Backuply adds scheduled incremental backups, remote uploads, rotation, and restores.
