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 The comment on the change is: Updating with basic stuff for Fedora 7 ------------------------------------------------------------------------------ {{{#!html <h2>Virtualization</h2>}}} - Virtualization in Fedora is based on Xen 3.0.2, and is integrated within the Fedora installer. Refer to [http://fedoraproject.org/wiki/Tools/Xen] for more information about Xen. + Virtualization in Fedora is based on Xen 3.0.4, and is integrated within the Fedora installer. Refer to [http://fedoraproject.org/wiki/Tools/Xen] for more information about Xen. = Types of Virtualization = - Under Fedora * using Xen 3.0.2, both paravirtualization and full virtualization can be implemented. Full virtualization requires a VT-capable processor. Paravirtualization does not require special hardware, but does require the guest OS to be modified. To learn more about how to configure and use Xen, refer to [http://fedoraproject.org/wiki/FedoraXenQuickstartFC6]. + Under Fedora * using Xen 3.0.4, both paravirtualization and full virtualization can be implemented. Full virtualization requires a VT-capable processor. Paravirtualization does not require special hardware, but does require the guest OS to be modified. To learn more about how to configure and use Xen, refer to [http://fedoraproject.org/wiki/FedoraXenQuickstartFC6]. = Guest Operating Systems = - The Fedora 6 development team has tested Xen with Fedora Core 6 and Red Hat Enterprise Linux 5 Beta1 guests. Other guests have not been tested. With paravirtualization, however, users can expect reasonable success running any Linux guest OS that was built for Xen 3.0.2. With full virtualization using VT hardware, users can expect reasonable success with a larger variety of operating systems, including some proprietary operating systems. + The Fedora 7 development team has tested Xen with Fedora Core 7 and Red Hat Enterprise Linux 5 Beta2 guests. Other guests have not been tested. With paravirtualization, however, users can expect reasonable success running any Linux guest OS that was built for Xen 3.0.4. With full virtualization using VT hardware, users can expect reasonable success with a larger variety of operating systems, including some proprietary operating systems. = Changes to the Xen Packages = - In Fedora a single kernel supports both the host and the guest operating systems. In previous versions, there was one kernel, `kernel-xenU`, for the host or hypervisor and a separate kernel, `kernel-xen0`, for the guests. In Fedora the `kernel-xen` package is the only kernel needed. + The following improvements have been made in the Virtualization packages in Fedora 7: - Fedora introduces `virt-manager`, a GUI application for installing and managing virtual machines. Features of `virt-manager` include: + * virt-manager and virsh can now work with inactive domains. Previously, only xm could handle inactive domains + * The mouse cursor problems with the virtual frame buffer have been fixed, for a better user experience in GUI modes + * Misc. other small improvements and fixes have been made. - * Integrated graphical framebuffer. Both the GUI installer and the guest operating system's graphical environment can be accessed from `virt-manager` without the need for VNC. - - * An embedded serial console viewer. The console can now be accessed from `virt-manager` without opening a separate terminal and using `xm console`. - - * CPU and memory management. The vCPUs and memory of active guest operating systems can be adjusted on the fly. - - * Extended RFB protocol handler. If the guest operating system changes screen resolution, the `virt-manager` graphical console adjusts its size accordingly. - - In Fedora there are two methods to install a guest OS: via the command line using the `xenguest-install` program, or via the GUI application `virt-manager`. - - [[Admonition("note","xenguest-install Script Renamed","The xenguest-install script was named xenguest-install.py in previous versions.")]] - - Xen log messages are stored under `/var/log/xen`, which separates Xen related log messages from other system messages. - - [[Admonition("important","i386 Guest Kernels Require PAE","PAE support in the CPU is required by i386 guests. Some older computers might not have this functionality.")]] - -- Fedora-relnotes-content mailing list Fedora-relnotes-content@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-relnotes-content
