In their own words
Citrix XenServer
Citrix XenServer is an enterprise virtualization platform for workloads in on-premises and hybrid environments. Its hypervisor pools compute, storage, and networking resources and allocates them to virtual machines. Hosts require XenServer OS on dedicated 64-bit x86 bare-metal servers, and the listed guest architecture is x86_64. The platform supports snapshots, GPU acceleration, high-availability policies, and live migration between hosts. A pool can contain up to 32 hosts. XenCenter runs on supported Windows systems; a standalone remote CLI can be installed on RPM-based Linux distributions. XenServer 9 uses a custom control-domain operating system, and new installations disable HTTP on the management interface, requiring TLS. GPU pass-through supports NVIDIA, AMD, and Intel GPUs; NVIDIA vGPU support for XenServer 9 is preview-only and not fully supported. XenServer is paid, with pricing available on request and a 90-day trial that does not include official support. The listed trial edition supports a three-host pool.
Virtualizor

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.
