concerned about attackers taking control of the guest and potentially
exploiting a QEMU security bug to compromise the host.

------------
+QEMU binaries
+-------------
By default, qemu-system-x86_64 is searched in $PATH to run the guest. If there
isn't one, or if it is older than 2.10, the test won't work. In this case,
provide the QEMU binary in env var: ``QEMU=/path/to/qemu-2.10+``.
+Likewise the path to qemu-img can be set in QEMU_IMG environment variable.

This machine type is very old and unmaintained. Users should use the 'malta'
machine type instead.

These machine types are very old and likely can not be used for live migration
from old QEMU versions anymore. A newer machine type should be used instead.

+When Xen is in use, this option controls whether Intel integrated graphics

+@item kernel-irqchip=on|off|split
+Controls KVM in-kernel irqchip support. The default is full acceleration of the
+interrupt controllers. On x86, split irqchip reduces the kernel attack
+surface, at a performance cost for non-MSI interrupts. Disabling the in-kernel
+irqchip completely is not recommended except for debugging purposes.

+Controls the size (in MiB) of the TCG translation block cache.
@item thread=single|multi
Controls number of TCG threads. When the TCG is multi-threaded there will be one
thread per vCPU therefor taking advantage of additional host cores. The default
the recommended is 320x240, 640x480, 800x640.
A timeout could be passed to bios, guest will pause for @var{rb_timeout} ms
-when boot failed, then reboot. If @option{reboot-timeout} is not set,

+when boot failed, then reboot. If @var{rb_timeout} is '-1', guest will not
+reboot, qemu passes '-1' to bios by default. Currently Seabios for X86

+# (* a blank line)?
+# * (Description:)? (Description of function)?
+# * (section header: (section description)? )*
+# (*)?*/
+#
+# So .. the trivial example would be:
+#
+# /**
+# * my_function
+# */
+#
+# If the Description: header tag is omitted, then there must be a blank line
+# after the last parameter specification.
+# e.g.
+# /**
+# * my_function - does my stuff
+# * @my_arg: its mine damnit
+# *
+# * Does my stuff explained.
+# */
+#
+# or, could also use:
+# /**
+# * my_function - does my stuff
+# * @my_arg: its mine damnit
+# * Description: Does my stuff explained.
+# */
+# etc.
+#
+# Besides functions you can also write documentation for structs, unions,
+# enums and typedefs. Instead of the function name you must write the name
+# of the declaration; the struct/union/enum/typedef must always precede
+# the name. Nesting of declarations is not supported.
+# Use the argument mechanism to document members or constants.
+# e.g.
+# /**
+# * struct my_struct - short description
+# * @a: first member
+# * @b: second member
+# *
+# * Longer description
+# */
+# struct my_struct {
+# int a;
+# int b;
+# /* private: */
+# int c;
+# };
+#
+# All descriptions can be multiline, except the short function description.
+#
+# For really longs structs, you can also describe arguments inside the
+# body of the struct.
+# eg.
+# /**
+# * struct my_struct - short description
+# * @a: first member
+# * @b: second member
+# *
+# * Longer description
+# */
+# struct my_struct {
+# int a;
+# int b;
+# /**
+# * @c: This is longer description of C
+# *
+# * You can use paragraphs to describe arguments
+# * using this method.
+# */
+# int c;
+# };
+#
+# This should be use only for struct/enum members.
+#
+# You can also add additional sections. When documenting kernel functions you
+# should document the "Context:" of the function, e.g. whether the functions
+# can be called form interrupts. Unlike other sections you can end it with an
+# empty line.
+# A non-void function should have a "Return:" section describing the return
+# value(s).
+# Example-sections should contain the string EXAMPLE so that they are marked
+# appropriately in DocBook.
+#
+# Example:
+# /**
+# * user_function - function that can only be called in user context
+# * @a: some argument
+# * Context: !in_interrupt()
+# *
+# * Some description
+# * Example:
+# * user_function(22);
+# */

+# All descriptive text is further processed, scanning for the following special
+# patterns, which are highlighted appropriately.
+#
+# 'funcname()' - function
+# '$ENVVAR' - environmental variable

-TODO-list:
-
-CPU common:
-- Unimplemented features/bugs:
- - Delay slot handling may fail sometimes (branch end of page, delay
- slot next page)
- - Atomical instructions
- - CPU features should match real CPUs (also ASI selection)
-- Optimizations/improvements:
- - Condition code/branch handling like x86, also for FPU?
- - Remove remaining explicit alignment checks
- - Global register for regwptr, so that windowed registers can be
- accessed directly
- - Improve Sparc32plus addressing
- - NPC/PC static optimisations (use JUMP_TB when possible)? (Is this
- obsolete?)
- - Synthetic instructions
- - MMU model dependent on CPU model
- - Select ASI helper at translation time (on V9 only if known)
- - KQemu/KVM support for VM only
- - Hardware breakpoint/watchpoint support
- - Cache emulation mode
- - Reverse-endian pages
- - Faster FPU emulation
