Xen Virtualization on SUSE Linux Enterprise Server 11 ®
SUSE Linux Enterprise Server ® Virtualization at Novell ® Host and Management Guest OS Management SUSE Linux Tools Enterprise Server Xen, KVM (SLES) “The Perfect Guest” “Novell is a Virtualization “Novell is an Operating Solution Provider” System Vendor” 16 © Novell, Inc. All rights reserved.
SUSE Linux Enterprise Server 11 ® Xen Virtualization • Integrated Xen hypervisor provides reliable, high performance virtualization • Xen 3.3.1 delivers advanced virtualization capabilities • Lowest cost solution – Host is included with OS, and you get unlimited VMs per system • Additional management solutions are available • Supports latest Intel processor and chipset-level virtualization advances – Intel VT FlexPriority – Intel VT FlexMigration – Intel VT for Direct I/O 17 © Novell, Inc. All rights reserved.
SUSE Linux Enterprise Server 11 ® Virtualization Host • Upgrade to Xen 3.3.1 delivers – Architectural improvements: better scalability, performance and security – Enhanced power management – Improved graphical capabilities • Open source management tools (virt-manager) • KVM technical preview • New paravirtualized drivers for Windows Vista and Windows Server 2008 18 © Novell, Inc. All rights reserved.
Xen Terminology
Xen Community Terminology • Domain: A container for a running virtual machine. Colloquially, the VM itself • Domain 0: The first domain container created. Privileged to 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 end services to virtual drivers. Typically this is dom0. • Physical Driver: A device driver that talks directly to the hardware • Virtual Driver: A device driver in a domU that fulfills requests by going to the physical driver in the driver domain 20 © Novell, Inc. All rights reserved.
Novell /Industry Terminology ® • Hypervisor: The entity that enables virtualization • Full-virtual: A VM mode that can run a native, unmodified operating 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 support virtualization technology, such as Intel VT or AMD-V. Required for fully virtual mode • Standard Computer: A computer that does not contain processor(s) that support virtualization technology and therefore can run VMs only in paravirtual mode • Native Operation System: A typical operating system that is not optimized for the paravirtual VM environment and must run in fully virtual mode or on “bare metal” 21 © Novell, Inc. All rights reserved.
Novell Terminology ® • VM Server: A server running Xen, or some other hypervisor, 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. All rights reserved.
Virtualization Modes and Xen Architecture
Virtualization Modes Full-Virtual – VMs can run native (unmodified) OS Apps Apps – Requires the need to trap and emulate all privileged instructions*, or emulate everything Operating Operating System System – Performance is negatively impacted Virtual Virtual – Also know as “HVM” virtual machines Machine Machine (full-virtual) (full-virtual) – Requires VT enabled CPU Virtualization Layer *Some processors are difficult to HW Platform fully virtualize such as traditional x86 24 © Novell, Inc. All rights reserved.
Virtualization Modes Paravirtual – Higher performance than full-virtualization Apps Apps – Hypervisor is supplemented with Operating Operating Management API an API that provides an assist for System System certain situations Virtual Virtual Machine Machine – Requires hardware dependent API (full-virtual) (full-virtual) portions of the VM OS to be modified to become aware of the Virtualization Layer virtualization layer – Allows VMs to avoid hard to HW Platform virtualize instructions by replacing them with a procedure call that provides the same functionality 25 © Novell, Inc. All rights reserved.
Virtualization Modes Virtualization Layer Enlightened Virtualization HW Platform – Hybrid of full and paravirtualization Apps Apps – OS is “enlightened” to know about paravirtual hypercalls Management API Operating Operating – Some parts of the OS can use System System paravirtual hypercalls other parts Virtual Virtual must use trap and emulation Native Machine Machine API (full-virtual) (full-virtual) – Performance is improved Adapter Requires VT enabled CPU Native – Virtualization Layer API HW Platform *For Windows Server 2008, enlightenment requires a 64 bit Xen Hypervisor 26 © Novell, Inc.

    Xen Community Terminology • Domain: A container for a running virtual machine. Colloquially, the VM itself • Domain 0: The first domain container created. Privileged to 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 end services to virtual drivers. Typically this is dom0. • Physical Driver: A device driver that talks directly to the hardware • Virtual Driver: A device driver in a domU that fulfills requests by going to the physical driver in the driver domain 20 © 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, unmodified operating 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 support virtualization technology, such as Intel VT or AMD-V. Required for fully virtual mode • Standard Computer: A computer that does not contain processor(s) that support virtualization technology and therefore can run VMs only in paravirtual mode • Native Operation System: A typical operating system that is not optimized for the paravirtual VM environment and must run in fully virtual mode or on “bare metal” 21 © Novell, Inc. All rights reserved.
  • 22.
    Novell Terminology ® • VM Server: A server running Xen, or some other hypervisor, 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. All rights reserved.

    Virtualization Modes and Xen Architecture
  • 24.
    Virtualization Modes Full-Virtual – VMs can run native (unmodified) OS Apps Apps – Requires the need to trap and emulate all privileged instructions*, or emulate everything Operating Operating System System – Performance is negatively impacted Virtual Virtual – Also know as “HVM” virtual machines Machine Machine (full-virtual) (full-virtual) – Requires VT enabled CPU Virtualization Layer *Some processors are difficult to HW Platform fully virtualize such as traditional x86 24 © Novell, Inc. All rights reserved.
  • 25.
    Virtualization Modes Paravirtual – Higher performance than full-virtualization Apps Apps – Hypervisor is supplemented with Operating Operating Management API an API that provides an assist for System System certain situations Virtual Virtual Machine Machine – Requires hardware dependent API (full-virtual) (full-virtual) portions of the VM OS to be modified to become aware of the Virtualization Layer virtualization layer – Allows VMs to avoid hard to HW Platform virtualize instructions by replacing them with a procedure call that provides the same functionality 25 © Novell, Inc. All rights reserved.
  • 26.
    Virtualization Modes Virtualization Layer Enlightened Virtualization HW Platform – Hybrid of full and paravirtualization Apps Apps – OS is “enlightened” to know about paravirtual hypercalls Management API Operating Operating – Some parts of the OS can use System System paravirtual hypercalls other parts Virtual Virtual must use trap and emulation Native Machine Machine API (full-virtual) (full-virtual) – Performance is improved Adapter Requires VT enabled CPU Native – Virtualization Layer API HW Platform *For Windows Server 2008, enlightenment requires a 64 bit Xen Hypervisor 26 © Novell, Inc.
