This is a pair of Xen para-virtual frontend device drivers: drivers/video/xen-fbfront.c provides a framebuffer, and drivers/input/xen-kbdfront provides keyboard and mouse. The backends run in dom0 user space. I started with the Xen version at http://xenbits.xensource.com/linux-2.6.18-xen.hg?rev/ca05cf1a9bdc Differences to that Xen version, for those who care: * Rewritten on top of fb deferred

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
