Virtualization in Fedora 11 includes major changes, and new features, that continue to support KVM, Xen, and many other virtual machine platforms.

+ <title>Improved VNC Authentication for Virtual Machine Management</title>
<para>
- 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.
+ Fedora 11 introduces the ability to use the SASL protocol for authenticating VNC connection to KVM and QEMU virtual machines. SASL is a pluggable system, allowing many different authentication mechanisms to be configured without changing the application code. The use of SASL, in combination with existing TLS encryption support, will allow clients like vinagre, virt-viewer and virt-manager 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 VNC server. This new authentication capability obsoletes the traditional VNC password scheme which is not sufficiently secure.

+ <title>Improved Graphical Console for Virtual Machines</title>
<para>
- This feature aims to improve the user experiance for virtual guests' graphical console, by providing an accurate mouse pointer and higher screen resolution, without requiring manual configuration.
+ Previous Fedora virtual guest consoles were limited to a screen resolution of 800x600, and the PS2 mouse pointer operated in relative coordinate mode. This prevented the guest pointer from tracking the local client pointer one for one.
</para>
<para>
+ Fedora 11 provides more accurate mouse pointer positioning and higher screen resolutions for virtual machine consoles. Fedora 11 guests default to a screen resolution of at least 1024x768, and are provided with a USB tablet in absolute coordinate mode. This results in a mouse pointer which tracks the local client pointer one for one.

+ <title>QEMU Updated to 0.10.0 </title>
+ <para>
+ QEMU is a generic and open source machine emulator and virtualizer.
+ </para>
+ <para>
+ When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performances.
+ </para>
+ <para>
+ When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. A host driver called the QEMU accelerator (also known as KQEMU) is needed in this case. The virtualizer mode requires that both the host and guest machine use x86 compatible processors.
