Linux operating system

Linux® virtual machines (VMs) are always supported in a paravirtualized mode.

Windows operating system

Windows VMs are always supported as hardware-based virtual machines (HVMs) with paravirtualized drivers for storage and network. The drivers are installed from the Citrix XenServer installation CDs.

If you plan to use Windows VMs running under Citrix XenServer, ensure that the server processors have hardware virtualization support, such as Intel Virtualization Technology (VT)-based processors or AMD-V-based processors.
