xen/xend-traditional-qemu.patch
Charles Arnold 86c3c4dd54 - bnc#837585 - xen* pkg update DISables xencommons and 
`xendomains` systemd services 
  xen.spec

- remove unneeded patch, autoload is handled by PCI device, without
  PCI device xen_platform_pci would not work anyway
  xen.sles11sp1.fate311487.xen_platform_pci.dmistring.patch

- Update our xen-3.0.4 version of unplug code in qemu-trad
  add comments about the usage of the code
  rename handler function
  reenable handlers for writing/reading from emulated PCI device

- Change unplugging of emulated devices in PVonHVM guests
  Since 3.0.4 xen-platform-pci.ko triggerd the unplug by writing
  to the PCI space of the emulated PCI device. 3.3 introduced an
  official unplug protocol. The option to unplug wit the official
  protocol is disabled per default.
  Remove our version and enable the unplug via official protocol

Subject: [PATCH] VNC: Support for ExtendedKeyEvent client message
This patch adds support for the ExtendedKeyEvent client message. This message
allows a client to send raw scan codes directly to the server. If the client
and server are using the same keymap, then it's unnecessary to use the '-k'
option with QEMU when this extension is supported.
This is extension is currently only implemented by gtk-vnc based clients
(gvncviewer, virt-manager, vinagre, etc.).
