Citrix XenServer
Citrix lists its corporate headquarters in Fort Lauderdale, Florida, United States.
What it is
Citrix XenServer is an enterprise virtualization platform for running workloads across on-premises and hybrid environments. Its hypervisor pools compute, storage, and networking resources so they can be allocated to virtual machines. Hosts run XenServer OS on dedicated 64-bit x86 bare-metal servers, with x86_64 listed as the guest architecture. The platform supports VM snapshots, GPU acceleration, high availability, and live migration between hosts. High availability policies can restart virtual machines on another host after a failure, while live migration supports maintenance with minimal or no downtime. XenServer is designed to integrate with existing networking and storage infrastructure, and a resource pool can contain up to 32 hosts. XenCenter provides desktop management on supported Windows systems; a standalone remote CLI can be installed on RPM-based Linux distributions. XenServer 9 requires TLS connections for new management-interface installations. GPU pass-through supports NVIDIA, AMD, and Intel GPUs, while NVIDIA vGPU support for XenServer 9 is preview status. Pricing is on request, with a 90-day trial and no free plan.
