Privilegedto affect (manage) other domains. a.k.a. dom0 Unprivileged Domain: Any domain other than domain 0.Cannot affect other domains. a.k.a. domU Driver Domain: Any domain that provides back endservices to virtual drivers. Typically this is dom0. Physical Driver: A device driver that talks directly tothe hardware Virtual Driver: A device driver in a domU that fulfillsrequests by going to the physical driver in the driver domain20 Novell, Inc. All rights reserved. 21. Novell /Industry Terminology Hypervisor: The entity that enables virtualization Full-virtual: A VM mode that can run a native, unmodifiedoperating system by emulating all hardware devices Paravirtual: A VM mode that can run a modified operating system,which cooperates with the Hypervisor VT Computer: A computer that contains processor(s) that supportvirtualization technology, such as Intel VT or AMD-V. Required forfully virtual mode Standard Computer: A computer that does not containprocessor(s) that support virtualization technology and thereforecan run VMs only in paravirtual mode Native Operation System: A typical operating system that is notoptimized for the paravirtual VM environment and must run in fullyvirtual mode or on bare metal 21 Novell, Inc. All rights reserved. 22. Novell Terminology VM Server: A server running Xen, or some otherhypervisor, capable of hosting VMs (i.e., xen + dom0)> Example: SUSE Linux Enterprise Server 10 with the Xen packages installed, booted with Xen VM: Virtual machines (domUs) Problematic terms Host, Guest, Domain Host and Guest suggest VMware's architecture Domain can be used synonymous with virtual machine in the Xen community 22 Novell, Inc.
