| == Virtualization == | | == AArch64 QEMU/KVM VM installation with libvirt and virt-manager support == |
| | You may now use '''libvirt''' and '''virt-manager''' to install a virtual machine on the AArch64 architecture with the KVM hypervisor. |
|
| |
|
| Virtualization in Fedora 11 includes major changes, and new features, that continue to support KVM, Xen, and many other virtual machine platforms.
| | Instructions are available here: |
|
| | * https://fedoraproject.org/wiki/Architectures/AArch64/Install_with_QEMU |
| === Improved VNC Authentication for Virtual Machine Management ===
| | * https://fedoraproject.org/wiki/QA:Testcase_Virt_AArch64_on_x86 |
| Fedora 11 introduces the ability to use the <code>SASL</code> protocol
| |
| for authenticating <code>VNC</code> connection to <code>KVM</code>
| |
| and <code>QEMU</code> virtual machines. <code>SASL</code> is a pluggable
| |
| system, allowing many different authentication mechanisms to be configured
| |
| without changing the application code. The use of <code>SASL</code>, in
| |
| combination with existing <code>TLS</code> encryption support, will allow clients like
| |
| <code>vinagre</code>, <code>virt-viewer</code> and <code>virt-manager</code>
| |
| to securely connect to remote virtual machine consoles hosted on Fedora
| |
| servers. In environments where Kerberos is deployed, this further allows for
| |
| secure single sign on to the <code>VNC</code> server. This new authentication
| |
| capability obsoletes the traditional <code>VNC</code> password scheme which
| |
| is not sufficiently secure.
| |
|
| |
|
| For further details refer to the [[Features/VirtVNCAuth|Virtualization VNC Authentication]] wiki page
| | == UEFI VMs installation with libvirt and virt-manager support == |
| | UEFI install options are now automatically available if UEFI/OVMF binaries are installed. |
|
| |
|
| === Improved Graphical Console for Virtual Machines ===
| | Instructions are available here: |
| Previous Fedora virtual guest consoles were limited to a screen
| |
| resolution of 800x600, and the <code>PS2</code> mouse pointer operated in
| |
| relative coordinate mode. This prevented the guest pointer from tracking
| |
| the local client pointer one for one.
| |
|
| |
|
| Fedora 11 provides more accurate mouse pointer positioning and higher
| | * https://fedoraproject.org/wiki/QA:Testcase_Virtualization_UEFI |
| screen resolutions for virtual machine consoles.
| | * https://fedoraproject.org/wiki/Using_UEFI_with_QEMU |
| Fedora 11 guests default to a screen resolution of at least 1024x768,
| |
| and are provided with a <code>USB</code> tablet in absolute coordinate
| |
| mode. This results in a mouse pointer which tracks the local client pointer one
| |
| for one.
| |
|
| |
|
| For further details refer to the [[Features/VirtImprovedConsole|Improved Graphical Console for Virtual Guests]] wiki page
| | == RBD and Gluster support with virt-install and virt-manager == |
|
| |
|
| === KVM PCI Device Assignment ===
| | '''virt-manager''' and '''virt-install''' is now supported for RBD and Gluster storage. Both tools can now |
| {{Admon/warning|Work in progress.|Feature is 95% complete.}}
| | easily use pre-configured gluster and rbd storage volumes. |
| Fedora 11 expands its virtualization capabilities to include <code>KVM</code> PCI device assignment support. <code>KVM</code> users can now give virtual machines exclusive access to physical PCI devices using Fedora's virtualization toools, including the Virtual Machine Manager application.
| |
| | |
| {{Admon/note|Hardware requirements|Intel <code>VT-d</code> or AMD <code>IOMMU</code> hardware platform support is required in order for this feature to be available.}}
| |
| | |
| For further details refer to the [[Features/KVM_PCI_Device_Assignment|KVM PCI Device Assignment]] wiki page.
| |
| | |
| === SVirt Mandatory Access Control ===
| |
| Fedora 11 integrates SELinux's Mandatory Access Control with Virtualization. Virtual machines can now be much more effectively isolated from the host and one another, giving the increased assurance that security flaws cannot be exploited by malicious guests.
| |
| | |
| For further details refer to the [[Features/SVirt_Mandatory_Access_Control|SVirt Mandatory Access Control]] wiki page.
| |
| | |
| === Other Improvements ===
| |
| | |
| Fedora also includes the following virtualization improvements:
| |
| | |
| ==== libvirt Updated to 0.6.1 ====
| |
| | |
| The <code>libvirt</code> package provides an API and tools to interact with the virtualization capabilities of recent versions of Linux (and other OSes). The <code>libvirt</code> software is designed to be a common denominator among all virtualization technologies with support for the following:

| |
| * Redesigned 'New Virtual Machine' wizard

| ==== virtinst Updated to 0.400.2 ====
| |
| The <code>python-virtinst</code> package contains tools for installing and manipulating multiple VM guest image formats.
| |
| | |
| '''New features and improvements since 0.400.0:''' | |
| * New <code>virt-clone</code> option <code>--original-xml</code>, allows cloning a guest from an xml file, rather than require an existing, defined guest.
| |
| * New <code>virt-install</code> option <code>--import</code>, allows creating a guest from an existing disk image, bypassing any OS install phase.
| |
| * New <code>virt-install</code> option <code>--host-device</code>, for connecting a physical host device to the guest.
| |
| * Allow specifying 'cache' value via <code>virt-install</code>'s <code>--disk</code> options (Ben Kochie)
| |
| * New <code>virt-install</code> option <code>--nonetworks</code> (John Levon)
| |
| * Add <code>virt-image</code> to <code>vmx</code> format support to <code>virt-convert</code>, replacing <code>virt-pack</code> (Joey Boggs)
| |
| * Add disk checksum support to <code>virt-image</code> (Joey Boggs)
| |
| * Enhanced URL install support: Debian Xen paravirt, Ubuntu kernel and boot.iso, Mandriva kernel, and Solaris Xen Paravirt (Guido Gunther, John Levon, Cole Robinson)
| |
| * Expanded test suite
| |
| * Numerous bug fixes, cleanups, and improvements

| |
| | |
| ==== Xen Updated to 3.3.1 ====
| |
| Fedora 11 supports booting as a domU guest, but will not function as a dom0 host until such support is provided in the upstream kernel. Support for a <code>pv_ops</code> dom0 is targeted for Xen 3.4.
| |
| | |
| '''Changes since 3.3.0:'''
| |
| * Xen 3.3.1 is a maintenance release in the 3.3 series.
| |
| | |
| For further details refer to:
| |
| | |
| * http://www.xen.org/download/roadmap.html -- Xen roadmap
| |
| * http://xenbits.xen.org/paravirt_ops/patches.hg/ -- paravirt_ops patch queue
| |
| | |
| === Xen Kernel Support ===
| |
| | |
| The <code>kernel</code> package in Fedora 11 supports booting as a guest domU, but will not function as a dom0 until such support is provided upstream. The most recent Fedora release with dom0 support is Fedora 8.
| |
| | |
| Booting a Xen domU guest within a Fedora 11 host requires the KVM based <code>xenner</code>. Xenner runs the guest kernel and a small Xen emulator together as a KVM guest.
| |
| | |
| {{Admon/important | KVM requires hardware virtualization features in the host system.| Systems lacking hardware virtualization do not support Xen guests at this time. }}
