Comparing Xen Open Source to XenServer

•Xen hypervisor is the core virtualization engine for both the open source and XenServer products

•Is supports paravirtualization and hardware virtualization assistance.  Both products offer stable, tested components

•Differences between Xen open source and XenServer include:• Xen open source code includes unstable or untested components

• Citrix XenServer products are rigorously tested and include polished features for heavy production use

• Citrix adds proprietary enterprise‐level software to the Xen hypervisor
