- Virtualization in Fedora 8 supports both Xen and KVM virtualization
- platforms. The <systemitem class="library">libvirt</systemitem> API
- and its corresponding tools, <application>virt-manager</application>
- and <command>virsh</command>, 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 9 includes major changes, and new features, that continue to support the Xen and KVM platforms.

+ <title>Kernel Integration Improvements</title>
+ <para>
+ Previously, the Xen kernel was created by forward-porting Xen bits from the 2.6.18 kernel into the current Fedora kernel. This task was arduous and labor intensive, and resulted in the Xen kernel being several releases behind the bare-metal kernel. The inclusion of paravirt ops now makes this process unnecessary. Once paravirt ops is merged upstream, Xen will no longer require a separate kernel.

+ Fullyvirtualized Linux guests now have 3 possible installation methods:

+ The latter allows for fully automated installation through the use of kickstart files. This provides parity between Xen HVM and KVM guests in terms of installation methods.

+ <title>Improved Storage Management</title>
+ <para>
+ Previously, Fedora introduced the ability to manage existing guest domains remotely using <package>libvirt</package>. It was not possible to create new guests due to the lack of storage management capabilities. In Fedora 9, new storage management can create and delete storage volumes from a remote host using <package>libvirt</package>.

+<section id="sn-PolicyKit-Integration">
+ <title>PolicyKit Integration</title>
+ <para>
+ Previously, the <command>virt-manager</command> application ran as root when managing a local hypervisor, and used <command>consolehelper</command> to authenticate from a desktop session. Running GTK applications as root is bad practice. PolicyKit integration now permits running <command>virt-manager</command> as a regular user.

+<section id="sn-Improved-Remote-Authentication">
+ <title>Improved Remote Authentication</title>
+ <para>
+ Previously, Fedora introduced support for secure remote management using TLS/SSL, and x509 certificates. Fedora 9 improves remote management capabilities by adding support for authentication by password database, Kerberos domain controller, or system authentication using PAM. This feature applies to all tools using <package>libvirt</package>.
