Hypothesis: %cr4 is a privileged register and can not be accessed from a paravirtualized xen domU? If running under xen is not support could you add a check for xen to the virtualbox kernel modules? 2) The upstream bug for this seems to be http://www.virtualbox.org/ticket/2383 -- System Information: Debian Release: 6.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/4 CPU cores) Locale: LANG=C, LC_CTYPE=fi_FI (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Versions of packages virtualbox-ose depends on: ii adduser 3.112+nmu2 add and remove users and groups ii libc6 2.11.2-7 Embedded GNU C Library: Shared lib ii libcurl3 7.21.0-1 Multi-protocol file transfer libra ii libgcc1 1:4.4.5-8 GCC support library ii libpng12-0 1.2.44-1 PNG library - runtime ii libpython2.6 2.6.6-8+b1 Shared Python runtime library (ver ii libsdl1.2debian 1.2.14-6.1 Simple DirectMedia Layer ii libssl0.9.8 0.9.8o-4 SSL shared libraries ii libstdc++6 4.4.5-8 The GNU Standard C++ Library v3 ii libvncserver0 0.9.7-2+b1 API to write one's own vnc server ii libx11-6 2:1.3.3-4 X11 client-side library ii libxcursor1 1:1.1.10-2 X cursor management library ii libxext6 2:1.1.2-1 X11 miscellaneous extension librar ii libxml2 2.7.8.dfsg-2 GNOME XML library ii libxmu6 2:1.0.5-2 X11 miscellaneous utility library ii libxt6 1:1.0.7-1 X11 toolkit intrinsics library ii python 2.6.6-3+squeeze5 interactive high-level object-orie ii python-central 0.6.16+nmu1 register and build utility for Pyt ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages virtualbox-ose recommends: ii libgl1-mesa-glx [libgl1] 7.7.1-4 A free implementation of the OpenG ii libqt4-opengl 4:4.6.3-4 Qt 4 OpenGL module ii libqtcore4 4:4.6.3-4 Qt 4 core module ii libqtgui4 4:4.6.3-4 Qt 4 GUI module ii virtualbox-ose-dkms 3.2.10-dfsg-1 x86 virtualization solution - kern ii virtualbox-ose-qt 3.2.10-dfsg-1 x86 virtualization solution - Qt b Versions of packages virtualbox-ose suggests: ii libasound2 1.0.23-2.1 shared library for ALSA applicatio ii libpulse0 0.9.21-3+b1 PulseAudio client libraries ii vde2 2.2.3-3 Virtual Distributed Ethernet pn virtualbox-guest-additions <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
