Dear Wiki user, You have subscribed to a wiki page or wiki category on "Fedora Project Wiki" for change notification. The following page has been changed by SamFolkWilliams: http://fedoraproject.org/wiki/Docs/Beats/Virtualization?action=diff&rev2=51&rev1=50 The comment on the change is: DRAFT for F9 - this will need major work ------------------------------------------------------------------------------ {{{#!html <h2>Virtualization</h2>}}} - Virtualization in Fedora [[GetVal(DocsDict,BeatsVer)]] supports both Xen and KVM virtualization platforms. The {{{libvirt}}} API and its corresponding tools, {{{virt-manager}}} and {{{virsh}}}, have been updated to support both KVM and Xen. Users can choose which virtualization platform to install, and use the same tools without regard to that choice. + Virtualization in Fedora [[GetVal(DocsDict,BeatsVer)]] has some major changes and new features that continue to support both the Xen and KVM platforms. - Xen in Fedora [[GetVal(DocsDict,BeatsVer)]] is based on version [[GetVal(DocsDict,xenVer)]]. + * para_virt ops in the kernel. Previously, the Xen kernel was created by forward-porting the Xen bits from 2.6.18 into the current Fedora kernel. This is an arduous task that was labor intensive and resulted in the Xen kernel being several releases behind the bare-metal kernel. The inclusion of para_virt ops means that this process is no longer necessary. Once para_virt ops is merged upstream, it will no longer be necessary to have a separate kernel for Xen. + * Improved storage management. Previously, Fedora introduced the ability to manage existing guest domains remotely using libvirt. It was not possible to create new guests due to lack of storage management capabilities. In Fedora [[GetVal(DocsDict,BeatsVer)]], new storage management tools add the ability to list, create and delete storage volumes from a remote host using libvirt. + * PolicyKit integration. Previously, the `virt-manager` application ran as root when managing a local hypervisor. It used `console-helper` to authentication from a desktop session. Running GTK applications as root is generally considered bad practice. By integrating with PolicyKit it is now possible to run `virt-manager` as a regular user. + * Improved remote authentication. Previously, Fedora introduced support for secure remote management using TLS/SSL and x509 certificates. Fedora [[GetVal(DocsDict,BeatsVer)]] improves remote management capabilities by adding support for authentication against a username/password database, Kerberos domain controller, or system-auth using PAM. This feature applies to all tools using libvirt. + * Introducing a P2V tool, shipping as a Live CD, which allows for the conversion of an existing bare-metal install to a virtual quest. + * Introducing `xenner` - a tool to run the Xen paravirt kernels on top of KVM + * Introducing paravirtual drivers for storage and network to KVM guests. - KVM in Fedora [[GetVal(DocsDict,BeatsVer)]] is based on version [[GetVal(DocsDict,KVMVer)]]. - - For more information on the differences between Xen and KVM, refer to http://virt.kernelnewbies.org/TechComparison. For more information on installing and using virtualization in Fedora [[GetVal(DocsDict,BeatsVer)]], refer to http://fedoraproject.org/wiki/Docs/Fedora8VirtQuickStart. - - === Changes to the Virtualization Packages === - - The following improvements have been made in the Virtualization packages in Fedora [[GetVal(DocsDict,BeatsVer)]]: - - * Secure remote management of guest domains. Features include: - * Secure remote management of guest VM lifecycle - * Secure remote access to the guest virtual consoles - * For more information on secure remote management, refer to http://fedoraproject.org/wiki/Releases/FeatureVirtSecurity. - * Introduction of '''Virt Viewer''', a lightweight, minimal UI for interacting with the graphical console of virtual machines. '''Virt Viewer''' serves as a replacement for `vncviewer`. - * The `LibVNCServer` implementation has been removed from Xen and replaced with '''QEMU'''. - * Introduction of '''GTK-VNC''', a GTK widget which provides a VNC client. For more information on '''GTK-VNC''' refer to http://gtk-vnc.sourceforge.net/. - -- Fedora-relnotes-content mailing list Fedora-relnotes-content@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-relnotes-content
