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.
