This is an update to the Linux part of the Xen PVFB. Linux Xen PVFB 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. Their backends run in dom0 user space. Parts in this patch series: 1. Enable Xen console by default in domU 2. Pointer z-axis (mouse wheel) support 3. Module aliases to support module autoloading 4. Zero unused bytes in events sent to backend 5. Dynamic mode support...

Hello all Xen devels, I''m writing howto''s in brazilian portuguese language about Xen-3.3.0 stubdom, pv-grub and others configurations. Following what is written in xen-3.3.0/stubdom/README, I tried start a HVM but without success. When I start the virtual machine calling ''xm create hvmtest'' command, in a few seconds the virtual machine is dead (see

Hey Daniel, I was looking at the xen-fbfront and a bit of Googling showed me that: http://xen.1045712.n5.nabble.com/PATCH-Add-grant-references-for-fbfront-kbdfront-td3332068.html you had posted patches for those two drivers to use grants. Are those patches still applicable? Shoudl they be rebased on top v3.13? Is there are a backend that uses it? Thanks!

I have spotted another couple of bugs when testing with xl on 4.1.0-rc and a xen/next-2.6.38 based kernel. If I use pygrub as a boot loader and run xl create -c host then the console disconnects once pygrub is finished. I can reconnect to the console session but it is a bit annoying to have to do so. If I set vfb = [ ''sdl'' ] in the configuration file, then I can type in the

Hello, Sometimes the backend of PVFB knows that it doesn''t need permanent refresh, when the window is minimized for instance (no refresh at all), or the administration tools know that the window is thumnailed, and so a slow refresh rate is fine. Also, some users may want to tune the refresh rate according to the smoothness they would like, balanced with the CPU time that requires.
