Citrix XenServer
Citrix XenServer is an enterprise virtualization platform for workloads across on-premises and hybrid environments.
What Citrix XenServer is
Citrix XenServer is an enterprise virtualization platform for workloads across on-premises and hybrid environments. Its hypervisor pools compute, storage, and networking resources for allocation to virtual machines. Hosts run XenServer OS on dedicated 64-bit x86 bare-metal servers, and the listed guest architecture is x86_64. XenServer supports VM snapshots, GPU acceleration, high-availability policies, and live migration between hosts. High availability can restart virtual machines on another host if one fails; live migration supports maintenance with minimal or no downtime. The platform is designed to integrate with existing storage and networking infrastructure, and a resource pool can contain up to 32 hosts. XenCenter runs on supported Windows systems, while a standalone remote CLI can be installed on RPM-based Linux distributions. XenServer 9 disables HTTP on the management interface for new installations and requires TLS connections. GPU pass-through supports NVIDIA, AMD, and Intel GPUs; NVIDIA vGPU support for XenServer 9 is a preview and not fully supported. Pricing is available on request, and a 90-day trial is offered without official support.
