-@section QEMU Accelerator Module

-The QEMU Accelerator Module (KQEMU) is an optional part of QEMU currently only
-available for Linux 2.4 or 2.6 x86 hosts. It enables QEMU to run x86
-code much faster. Provided it is installed on your PC (see
-@ref{kqemu_install}), QEMU will automatically use it.
-
-WARNING: as with any alpha stage kernel driver, KQEMU may cause
-arbitrary data loss on your PC, so you'd better backup your sensitive
-data before using it.
-
-When using KQEMU, QEMU will create a big hidden file containing the
-RAM of the virtual machine. For best performance, it is important that
-this file is kept in RAM and not on the hard disk. QEMU uses the
-@file{/dev/shm} directory to create this file because @code{tmpfs} is
-usually mounted on it (check with the shell command
-@code{df}). Otherwise @file{/tmp} is used as fallback. You can use the
-@var{QEMU_TMPDIR} shell variable to set a new directory for the QEMU
-RAM file.
-
-KQEMU has only been tested with Linux 2.4, Linux 2.6 and Windows 2000
-as guest OSes. If your guest OS do not work with KQEMU, you can
-dynamically disable KQEMU with the @option{-no-kqemu} option.

-@subsection QEMU Accelerator Installation
-
-If you use x86 Linux, the compilation of the QEMU Accelerator Kernel
-Module (KQEMU) is automatically activated provided you have the
-necessary kernel headers. If nonetheless the compilation fails, you
-can disable its compilation with the @option{--disable-kqemu} option.
-
-If you are using a 2.6 host kernel, then all the necessary kernel
-headers should be already installed. If you are using a 2.4 kernel,
-then you should verify that properly configured kernel sources are
-installed and compiled. On a Redhat 9 distribution for example, the
-following must be done:
-@example
-1) Install the kernel-source-xxx package
-2) cd /usr/src/linux-xxx
-3) make distclean
-4) Copy /boot/config-vvv in .config (use uname -r to know your configuration name 'vvv')
-5) Edit the Makefile to change the EXTRAVERSION line to match your
- current configuration name:
- EXTRAVERSION = -custom
-to
- EXTRAVERSION = -8 # This is an example, it can be -8smp too
-5) make menuconfig # Just save the configuration
-6) make dep bzImage
-@end example
-
-The installation of KQEMU is not fully automatic because it is highly
-distribution dependent. When launching
-@example
-make install
-@end example
-
-KQEMU is installed in /lib/modules/@var{kernel_version}/misc. The
-device @file{/dev/kqemu} is created with read/write access rights for
-everyone. If you fear security issues, you can restrict the access
-rights of @file{/dev/kqemu}.
-
-If you want that KQEMU is installed automatically at boot time, you can add
-
-@example
-# Load the KQEMU kernel module
-/sbin/modprobe kqemu
-@end example
-
-in @file{/etc/rc.d/rc.local}.
-
-If your distribution uses udev (like Fedora), the @file{/dev/kqemu} is
-not created automatically (yet) at every reboot. You can add the
-following in @file{/etc/rc.d/rc.local}:
-
-@example
-# Create the KQEMU device
-mknod /dev/kqemu c 250 0
-chmod 666 /dev/kqemu
