|
| == 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 |
| === Virtualization VNC Authentication ===
| | * https://fedoraproject.org/wiki/QA:Testcase_Virt_AArch64_on_x86 |
| {{Admon/warning|Work in progress.|Feature is not yet complete.}}
| |
| Define a mapping of SASL authentication into the VNC protocol, and implement it for QEMU and GTK-VNC, providing strongly authenticated, securely encrypted remote access of virtual guest consoles.
| |
|
| |
|
| 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. |
|
| |
|
| === KVM PCI Device Assignment ===
| | Instructions are available here: |
| {{Admon/warning|Work in progress.|Feature is not yet complete.}}
| |
| Fedora 11 expands its virtualization capabilities to include KVM PCI device assignment support. KVM users can now give virtual machines exclusive access to physical PCI devices using Fedora's virtualization toools, including the Virtual Machine Manager application.
| |
|
| |
|
| Intel VT-d or AMD IOMMU hardware platform support is required in order for this feature to be available.

| | == RBD and Gluster support with virt-install and virt-manager == |
|
| |
|
| === KVM and QEMU merge ===
| | '''virt-manager''' and '''virt-install''' is now supported for RBD and Gluster storage. Both tools can now |
| {{Admon/warning|Work in progress.|Feature is not yet complete.}}
| | easily use pre-configured gluster and rbd storage volumes. |
| Fedora 11 includes a merge of the qemu and kvm RPMs. The merging of the two codebases continues upstream, but the Fedora package maintainers have chosen to merge the packages in order reduce the maintainership burden and provide better support.
| |
| | |
| For further details refer to the [[Features/KVM_and_QEMU_merge|KVM_and_QEMU_merge]] wiki page
| |
| | |
| === Shared Network Interface ===
| |
| {{Admon/warning|Work in progress.|Feature is not yet complete.}}
| |
| Fedora 11 adds the ability to configure shared network interfaces for improved virtual machine connectivity. This enables virtual machines to be bridged directly to same the physical network as the host machine.
| |
| | |
| For further details refer to the [[Features/Shared_Network_Interface|Shared Network Interface]] wiki page.
| |
| | |
| === SVirt Mandatory Access Control ===
| |
| {{Admon/warning|Work in progress.|Feature is not yet complete.}}
| |
| 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 0.6.0 ====
| |
| | |
| 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:
| |
| | |
| * The Xen hypervisor on Linux and Solaris hosts.
| |
| * The QEMU emulator
| |
| * The KVM Linux hypervisor
| |
| * The LXC Linux container system
| |
| * The OpenVZ Linux container system
| |
| * Storage on IDE/SCSI/USB disks, FibreChannel, LVM, iSCSI, and NFS
| |
| | |
| '''New features and improvements since 0.4.6:'''
| |
| * thread safety of the API and event handling
| |
| * allow QEmu domains to survive daemon restart
| |
| * extended logging capabilities
| |
| * support copy-on-write storage volumes
| |
| * support of storage cache control options for QEmu/KVM
| |
| * driver infrastructure and locking
| |
| * Test driver infrastructure
| |
| * parallelism in the daemon and associated config
| |
| * virsh help cleanups
| |
| * logrotate daemon logs
| |
| * more regression tests
| |
| * QEmu SDL graphics
| |
| * add --version flag to daemon
| |
| * memory consumption cleanup
| |
| * QEmu pid file and XML states for daemon restart
| |
| * gnulib updates
| |
| * PCI passthrough for KVM
| |
| * generic internal thread API
| |
| * RHEL-5 specific Xen configure option and code
| |
| * save domain state as string in status file
| |
| * add locking to all API entry points
| |
| * new ref counting APIs
| |
| * IP address for Xen bridges
| |
| * driver format for disk file types
| |
| * improve QEmu/KVM tun/tap performances
| |
| * enable floppies for Xen fully virt
| |
| * support VNC password settings for QEmu/KVM
| |
| * qemu driver version reporting
| |
| | |
| There were also dozens of cleanups, documentation enhancements, portability and bug fixes. For further details refer to: http://www.libvirt.org/news.html
| |
| | |
| ==== virt-manager Updated to 0.6.1 ====
| |
| The <code>virt-manager</code> package provides a GUI implementation of <code>virtinst</code> and <code>libvirt</code> functionality.
| |
| | |

| |
| | |
| ==== virtinst Updated to 0.400.1 ====
| |
| 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:''' | |
| * Add virt-image -> vmx support to virt-convert, replacing virt-pack (Joey Boggs)
| |
| * Add disk checksum support to virt-image (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)

| * http://virt-manager.et.redhat.com/
| |
| | |
| ==== 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. }}
