  • 2. 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 2 © 2008 Citrix Systems, Inc. — All rights reserved
