16 | 1f673135 | bellard | QEMU is a FAST! processor emulator using dynamic translation to |
17 | 1f673135 | bellard | achieve good emulation speed. |
18 | 1eb20527 | bellard | |
19 | 1eb20527 | bellard | QEMU has two operating modes: |

24 | 1f673135 | bellard | Full system emulation. In this mode, QEMU emulates a full system (for |
25 | 1f673135 | bellard | example a PC), including a processor and various peripherials. It can |
26 | 1f673135 | bellard | be used to launch different Operating Systems without rebooting the |
27 | 1f673135 | bellard | PC or to debug system code. |
28 | 1eb20527 | bellard | |
29 | 0806e3f6 | bellard | @item |
30 | 1f673135 | bellard | User mode emulation (Linux host only). In this mode, QEMU can launch |
31 | 1f673135 | bellard | Linux processes compiled for one CPU on another CPU. It can be used to |
32 | 1f673135 | bellard | launch the Wine Windows API emulator (@url{http://www.winehq.org}) or |
33 | 1f673135 | bellard | to ease cross-compilation and cross-debugging. |

36 | 1eb20527 | bellard | |
37 | 1f673135 | bellard | As QEMU requires no host kernel driver to run, it is very safe and |
38 | 1eb20527 | bellard | easy to use. |
39 | 322d0c66 | bellard | |
40 | 52c00a5f | bellard | For system emulation, the following hardware targets are supported: |
41 | 52c00a5f | bellard | @itemize |

77 | 0806e3f6 | bellard | |
78 | 0806e3f6 | bellard | @c man begin DESCRIPTION |
79 | 0806e3f6 | bellard | |
80 | 52c00a5f | bellard | The QEMU System emulator simulates a complete PC. |
81 | 0806e3f6 | bellard | |
82 | 0806e3f6 | bellard | In order to meet specific user needs, two versions of QEMU are |
83 | 0806e3f6 | bellard | available: |
84 | 0806e3f6 | bellard | |
85 | 0806e3f6 | bellard | @enumerate |
86 | 0806e3f6 | bellard | |
87 | 0806e3f6 | bellard | @item |
88 | 15a34c63 | bellard | @code{qemu-fast} uses the host Memory Management Unit (MMU) to |
89 | 15a34c63 | bellard | simulate the x86 MMU. It is @emph{fast} but has limitations because |
90 | 15a34c63 | bellard | the whole 4 GB address space cannot be used and some memory mapped |
91 | 15a34c63 | bellard | peripherials cannot be emulated accurately yet. Therefore, a specific |
92 | 3eb2619f | bellard | guest Linux kernel can be used (@xref{linux_compile}) as guest |
93 | 3eb2619f | bellard | OS. |
94 | 3eb2619f | bellard | |
95 | 3eb2619f | bellard | Moreover there is no separation between the host and target address |
96 | 3eb2619f | bellard | spaces, so it offers no security (the target OS can modify the |
97 | 3eb2619f | bellard | @code{qemu-fast} code by writing at the right addresses). |
98 | 0806e3f6 | bellard | |
99 | 0806e3f6 | bellard | @item |
100 | 3eb2619f | bellard | @code{qemu} uses a software MMU. It is about @emph{two times slower} |
101 | 3eb2619f | bellard | but gives a more accurate emulation and a complete separation between |
102 | 3eb2619f | bellard | the host and target address spaces. |
103 | 0806e3f6 | bellard | |
104 | 0806e3f6 | bellard | @end enumerate |
105 | 0806e3f6 | bellard | |
106 | 0806e3f6 | bellard | QEMU emulates the following PC peripherials: |

150 | ec410fc9 | bellard | |
151 | 0806e3f6 | bellard | @c man begin OPTIONS |
152 | 9d4520d0 | bellard | @var{disk_image} is a raw hard disk image for IDE hard disk 0. |
153 | ec410fc9 | bellard | |
154 | ec410fc9 | bellard | General options: |
155 | ec410fc9 | bellard | @table @option |
156 | 2be3bc02 | bellard | @item -fda file |
157 | 2be3bc02 | bellard | @item -fdb file |
158 | be3edd95 | bellard | Use @var{file} as floppy disk 0/1 image (@xref{disk_images}). You can |
159 | be3edd95 | bellard | use the host floppy by using @file{/dev/fd0} as filename. |
160 | 2be3bc02 | bellard | |
161 | ec410fc9 | bellard | @item -hda file |
162 | ec410fc9 | bellard | @item -hdb file |
163 | 181f1558 | bellard | @item -hdc file |
164 | 181f1558 | bellard | @item -hdd file |
165 | 2be3bc02 | bellard | Use @var{file} as hard disk 0, 1, 2 or 3 image (@xref{disk_images}). |
166 | 1f47a922 | bellard | |
167 | 181f1558 | bellard | @item -cdrom file |
168 | 181f1558 | bellard | Use @var{file} as CD-ROM image (you cannot use @option{-hdc} and and |
169 | be3edd95 | bellard | @option{-cdrom} at the same time). You can use the host CD-ROM by |
170 | be3edd95 | bellard | using @file{/dev/cdrom} as filename. |
171 | 181f1558 | bellard | |
172 | 1f673135 | bellard | @item -boot [a|c|d] |
173 | 1f673135 | bellard | Boot on floppy (a), hard disk (c) or CD-ROM (d). Hard disk boot is |
174 | 2be3bc02 | bellard | the default. |
175 | 1f47a922 | bellard | |
176 | 181f1558 | bellard | @item -snapshot |
177 | 1f47a922 | bellard | Write to temporary files instead of disk image files. In this case, |
178 | 1f47a922 | bellard | the raw disk image you use is not written back. You can however force |
179 | 1f47a922 | bellard | the write back by pressing @key{C-a s} (@xref{disk_images}). |
180 | ec410fc9 | bellard | |
181 | ec410fc9 | bellard | @item -m megs |
182 | 15a34c63 | bellard | Set virtual RAM size to @var{megs} megabytes. Default is 128 MB. |
183 | ec410fc9 | bellard | |
184 | 0806e3f6 | bellard | @item -nographic |
185 | 0806e3f6 | bellard | |
186 | 0806e3f6 | bellard | Normally, QEMU uses SDL to display the VGA output. With this option, |
187 | 0806e3f6 | bellard | you can totally disable graphical output so that QEMU is a simple |
188 | 0806e3f6 | bellard | command line application. The emulated serial port is redirected on |
189 | 0806e3f6 | bellard | the console. Therefore, you can still use QEMU to debug a Linux kernel |
190 | 0806e3f6 | bellard | with a serial console. |
191 | 0806e3f6 | bellard | |
192 | 3d11d0eb | bellard | @item -k language |
193 | 3d11d0eb | bellard | |
194 | 3d11d0eb | bellard | Use keyboard layout @var{language} (for example @code{fr} for |
195 | 3d11d0eb | bellard | French). This option is only needed where it is not easy to get raw PC |
196 | 3d11d0eb | bellard | keycodes (e.g. on Macs or with some X11 servers). You don't need to |
197 | 3d11d0eb | bellard | use it on PC/Linux or PC/Windows hosts. |
198 | 3d11d0eb | bellard | |
199 | 3d11d0eb | bellard | The available layouts are: |
200 | 3d11d0eb | bellard | @example |
201 | 3d11d0eb | bellard | ar de-ch es fo fr-ca hu ja mk no pt-br sv |
202 | 3d11d0eb | bellard | da en-gb et fr fr-ch is lt nl pl ru th |
203 | 3d11d0eb | bellard | de en-us fi fr-be hr it lv nl-be pt sl tr |
204 | 3d11d0eb | bellard | @end example |
205 | 3d11d0eb | bellard | |
206 | 3d11d0eb | bellard | The default is @code{en-us}. |
207 | 3d11d0eb | bellard | |
208 | a8c490cd | bellard | @item -enable-audio |
209 | a8c490cd | bellard | |
210 | a8c490cd | bellard | The SB16 emulation is disabled by default as it may give problems with |
211 | a8c490cd | bellard | Windows. You can enable it manually with this option. |
212 | a8c490cd | bellard | |
213 | 15a34c63 | bellard | @item -localtime |
214 | 15a34c63 | bellard | Set the real time clock to local time (the default is to UTC |
215 | 15a34c63 | bellard | time). This option is needed to have correct date in MS-DOS or |
216 | 15a34c63 | bellard | Windows. |
217 | 15a34c63 | bellard | |
218 | d63d307f | bellard | @item -full-screen |
219 | d63d307f | bellard | Start in full screen. |
220 | d63d307f | bellard | |
221 | f7cce898 | bellard | @item -pidfile file |
222 | f7cce898 | bellard | Store the QEMU process PID in @var{file}. It is useful if you launch QEMU |
223 | f7cce898 | bellard | from a script. |
224 | f7cce898 | bellard | |

231 | 1f673135 | bellard | @item -n script |
232 | 52c00a5f | bellard | Set TUN/TAP network init script [default=/etc/qemu-ifup]. This script |
233 | 52c00a5f | bellard | is launched to configure the host network interface (usually tun0) |
234 | 1f673135 | bellard | corresponding to the virtual NE2000 card. |
235 | 1f673135 | bellard | |
236 | 1f673135 | bellard | @item -macaddr addr |
237 | 1f673135 | bellard | |
238 | 1f673135 | bellard | Set the mac address of the first interface (the format is |
239 | 1f673135 | bellard | aa:bb:cc:dd:ee:ff in hexa). The mac address is incremented for each |
240 | 1f673135 | bellard | new network interface. |
241 | 1f673135 | bellard | |
242 | 52c00a5f | bellard | @item -tun-fd fd |
243 | 52c00a5f | bellard | Assumes @var{fd} talks to a tap/tun host network interface and use |
244 | 52c00a5f | bellard | it. Read @url{http://bellard.org/qemu/tetrinet.html} to have an |
245 | 52c00a5f | bellard | example of its use. |
246 | 52c00a5f | bellard | |
247 | 52c00a5f | bellard | @item -user-net |
248 | 15a34c63 | bellard | Use the user mode network stack. This is the default if no tun/tap |
249 | 15a34c63 | bellard | network init script is found. |
250 | 52c00a5f | bellard | |
251 | 9bf05444 | bellard | @item -tftp prefix |
252 | 9bf05444 | bellard | When using the user mode network stack, activate a built-in TFTP |
253 | 9bf05444 | bellard | server. All filenames beginning with @var{prefix} can be downloaded |
254 | 9bf05444 | bellard | from the host to the guest using a TFTP client. The TFTP client on the |
255 | 9bf05444 | bellard | guest must be configured in binary mode (use the command @code{bin} of |
256 | 9bf05444 | bellard | the Unix TFTP client). The host IP address on the guest is as usual |
257 | 9bf05444 | bellard | 10.0.2.2. |
258 | 9bf05444 | bellard | |
259 | 2518bd0d | bellard | @item -smb dir |
260 | 2518bd0d | bellard | When using the user mode network stack, activate a built-in SMB |
261 | 2518bd0d | bellard | server so that Windows OSes can access to the host files in @file{dir} |
262 | 2518bd0d | bellard | transparently. |
263 | 2518bd0d | bellard | |
264 | 2518bd0d | bellard | In the guest Windows OS, the line: |
265 | 2518bd0d | bellard | @example |
266 | 2518bd0d | bellard | 10.0.2.4 smbserver |
267 | 2518bd0d | bellard | @end example |
268 | 2518bd0d | bellard | must be added in the file @file{C:\WINDOWS\LMHOSTS} (for windows 9x/Me) |
269 | 2518bd0d | bellard | or @file{C:\WINNT\SYSTEM32\DRIVERS\ETC\LMHOSTS} (Windows NT/2000). |
270 | 2518bd0d | bellard | |
271 | 2518bd0d | bellard | Then @file{dir} can be accessed in @file{\\smbserver\qemu}. |
272 | 2518bd0d | bellard | |
273 | 2518bd0d | bellard | Note that a SAMBA server must be installed on the host OS in |
274 | 2518bd0d | bellard | @file{/usr/sbin/smbd}. QEMU was tested succesfully with smbd version |
275 | 2518bd0d | bellard | 2.2.7a from the Red Hat 9. |
276 | 2518bd0d | bellard | |
277 | 9bf05444 | bellard | @item -redir [tcp|udp]:host-port:[guest-host]:guest-port |
278 | 9bf05444 | bellard | |
279 | 9bf05444 | bellard | When using the user mode network stack, redirect incoming TCP or UDP |
280 | 9bf05444 | bellard | connections to the host port @var{host-port} to the guest |
281 | 9bf05444 | bellard | @var{guest-host} on guest port @var{guest-port}. If @var{guest-host} |
282 | 9bf05444 | bellard | is not specified, its value is 10.0.2.15 (default address given by the |
283 | 9bf05444 | bellard | built-in DHCP server). |
284 | 9bf05444 | bellard | |
285 | 9bf05444 | bellard | For example, to redirect host X11 connection from screen 1 to guest |
286 | 9bf05444 | bellard | screen 0, use the following: |
287 | 9bf05444 | bellard | |
288 | 9bf05444 | bellard | @example |
289 | 9bf05444 | bellard | # on the host |
290 | 9bf05444 | bellard | qemu -redir tcp:6001::6000 [...] |
291 | 9bf05444 | bellard | # this host xterm should open in the guest X11 server |
292 | 9bf05444 | bellard | xterm -display :1 |
293 | 9bf05444 | bellard | @end example |
294 | 9bf05444 | bellard | |
295 | 9bf05444 | bellard | To redirect telnet connections from host port 5555 to telnet port on |
296 | 9bf05444 | bellard | the guest, use the following: |

611 | 1f47a922 | bellard | @section Disk Images |
612 | 1f47a922 | bellard | |
613 | acd935ef | bellard | Since version 0.6.1, QEMU supports many disk image formats, including |
614 | acd935ef | bellard | growable disk images (their size increase as non empty sectors are |
615 | acd935ef | bellard | written), compressed and encrypted disk images. |
616 | 1f47a922 | bellard | |
617 | acd935ef | bellard | @subsection Quick start for disk image creation |
618 | acd935ef | bellard | |
619 | acd935ef | bellard | You can create a disk image with the command: |
620 | 1f47a922 | bellard | @example |
621 | acd935ef | bellard | qemu-img create myimage.img mysize |
622 | 1f47a922 | bellard | @end example |
623 | acd935ef | bellard | where @var{myimage.img} is the disk image filename and @var{mysize} is its |
624 | acd935ef | bellard | size in kilobytes. You can add an @code{M} suffix to give the size in |
625 | acd935ef | bellard | megabytes and a @code{G} suffix for gigabytes. |
626 | acd935ef | bellard | |
627 | acd935ef | bellard | @xref{qemu_img_invocation} for more information. |
628 | 1f47a922 | bellard | |
629 | 1f47a922 | bellard | @subsection Snapshot mode |
630 | 1f47a922 | bellard | |
631 | 1f47a922 | bellard | If you use the option @option{-snapshot}, all disk images are |
632 | 1f47a922 | bellard | considered as read only. When sectors in written, they are written in |
633 | 1f47a922 | bellard | a temporary file created in @file{/tmp}. You can however force the |
634 | acd935ef | bellard | write back to the raw disk images by using the @code{commit} monitor |
635 | acd935ef | bellard | command (or @key{C-a s} in the serial console). |

642 | 9d4fb82e | bellard | @section Network emulation |
643 | 9d4fb82e | bellard | |
644 | 9d4fb82e | bellard | QEMU simulates up to 6 networks cards (NE2000 boards). Each card can |
645 | 9d4fb82e | bellard | be connected to a specific host network interface. |
646 | 9d4fb82e | bellard | |
647 | 9d4fb82e | bellard | @subsection Using tun/tap network interface |
648 | 9d4fb82e | bellard | |
649 | 9d4fb82e | bellard | This is the standard way to emulate network. QEMU adds a virtual |
650 | 9d4fb82e | bellard | network device on your host (called @code{tun0}), and you can then |
651 | 9d4fb82e | bellard | configure it as if it was a real ethernet card. |
652 | 9d4fb82e | bellard | |
653 | 9d4fb82e | bellard | As an example, you can download the @file{linux-test-xxx.tar.gz} |
654 | 9d4fb82e | bellard | archive and copy the script @file{qemu-ifup} in @file{/etc} and |
655 | 9d4fb82e | bellard | configure properly @code{sudo} so that the command @code{ifconfig} |
656 | 9d4fb82e | bellard | contained in @file{qemu-ifup} can be executed as root. You must verify |
657 | 9d4fb82e | bellard | that your host kernel supports the TUN/TAP network interfaces: the |
658 | 9d4fb82e | bellard | device @file{/dev/net/tun} must be present. |
659 | 9d4fb82e | bellard | |
660 | 9d4fb82e | bellard | See @ref{direct_linux_boot} to have an example of network use with a |
661 | 9d4fb82e | bellard | Linux distribution. |
662 | 9d4fb82e | bellard | |
663 | 9d4fb82e | bellard | @subsection Using the user mode network stack |
664 | 9d4fb82e | bellard | |
665 | 443f1376 | bellard | By using the option @option{-user-net} or if you have no tun/tap init |
666 | 443f1376 | bellard | script, QEMU uses a completely user mode network stack (you don't need |
667 | 443f1376 | bellard | root priviledge to use the virtual network). The virtual network |
668 | 443f1376 | bellard | configuration is the following: |
669 | 9d4fb82e | bellard | |
670 | 9d4fb82e | bellard | @example |
671 | 9d4fb82e | bellard | |
672 | 9d4fb82e | bellard | QEMU Virtual Machine <------> Firewall/DHCP server <-----> Internet |
673 | 9d4fb82e | bellard | (10.0.2.x) | (10.0.2.2) |
674 | 9d4fb82e | bellard | | |
675 | 2518bd0d | bellard | ----> DNS server (10.0.2.3) |
676 | 2518bd0d | bellard | | |
677 | 2518bd0d | bellard | ----> SMB server (10.0.2.4) |
678 | 9d4fb82e | bellard | @end example |
679 | 9d4fb82e | bellard | |
680 | 9d4fb82e | bellard | The QEMU VM behaves as if it was behind a firewall which blocks all |
681 | 9d4fb82e | bellard | incoming connections. You can use a DHCP client to automatically |
682 | 9d4fb82e | bellard | configure the network in the QEMU VM. |
683 | 9d4fb82e | bellard | |
684 | 9d4fb82e | bellard | In order to check that the user mode network is working, you can ping |
685 | 9d4fb82e | bellard | the address 10.0.2.2 and verify that you got an address in the range |
686 | 9d4fb82e | bellard | 10.0.2.x from the QEMU virtual DHCP server. |
687 | 9d4fb82e | bellard | |
688 | b415a407 | bellard | Note that @code{ping} is not supported reliably to the internet as it |
689 | b415a407 | bellard | would require root priviledges. It means you can only ping the local |
690 | b415a407 | bellard | router (10.0.2.2). |
691 | b415a407 | bellard | |
692 | 9bf05444 | bellard | When using the built-in TFTP server, the router is also the TFTP |
693 | 9bf05444 | bellard | server. |
694 | 9bf05444 | bellard | |
695 | 9bf05444 | bellard | When using the @option{-redir} option, TCP or UDP connections can be |
696 | 9bf05444 | bellard | redirected from the host to the guest. It allows for example to |
697 | 9bf05444 | bellard | redirect X11, telnet or SSH connections. |

710 | 1f673135 | bellard | |
711 | 1f673135 | bellard | @item Optional: If you want network support (for example to launch X11 examples), you |
712 | 1f673135 | bellard | must copy the script @file{qemu-ifup} in @file{/etc} and configure |
713 | 1f673135 | bellard | properly @code{sudo} so that the command @code{ifconfig} contained in |
714 | 1f673135 | bellard | @file{qemu-ifup} can be executed as root. You must verify that your host |
715 | 1f673135 | bellard | kernel supports the TUN/TAP network interfaces: the device |
716 | 1f673135 | bellard | @file{/dev/net/tun} must be present. |
717 | 1f673135 | bellard | |
718 | 1f673135 | bellard | When network is enabled, there is a virtual network connection between |
719 | 1f673135 | bellard | the host kernel and the emulated kernel. The emulated kernel is seen |
720 | 1f673135 | bellard | from the host kernel at IP address 172.20.0.2 and the host kernel is |
721 | 1f673135 | bellard | seen from the emulated kernel at IP address 172.20.0.1. |

926 | da415d54 | bellard | @section GDB usage |
927 | da415d54 | bellard | |
928 | da415d54 | bellard | QEMU has a primitive support to work with gdb, so that you can do |
929 | 0806e3f6 | bellard | 'Ctrl-C' while the virtual machine is running and inspect its state. |
930 | da415d54 | bellard | |
931 | 9d4520d0 | bellard | In order to use gdb, launch qemu with the '-s' option. It will wait for a |
932 | da415d54 | bellard | gdb connection: |
933 | da415d54 | bellard | @example |
934 | 6c9bf893 | bellard | > qemu -s -kernel arch/i386/boot/bzImage -hda root-2.4.20.img -append "root=/dev/hda" |
935 | da415d54 | bellard | Connected to host network interface: tun0 |

937 | da415d54 | bellard | @end example |
938 | da415d54 | bellard | |
939 | da415d54 | bellard | Then launch gdb on the 'vmlinux' executable: |
940 | da415d54 | bellard | @example |
941 | da415d54 | bellard | > gdb vmlinux |
942 | da415d54 | bellard | @end example |
943 | da415d54 | bellard | |
944 | da415d54 | bellard | In gdb, connect to QEMU: |
945 | da415d54 | bellard | @example |
946 | 6c9bf893 | bellard | (gdb) target remote localhost:1234 |
947 | da415d54 | bellard | @end example |
948 | da415d54 | bellard | |
949 | da415d54 | bellard | Then you can use gdb normally. For example, type 'c' to launch the kernel: |
950 | da415d54 | bellard | @example |
951 | da415d54 | bellard | (gdb) c |
952 | da415d54 | bellard | @end example |

969 | 1a084f3d | bellard | |
970 | 15a34c63 | bellard | To have access to SVGA graphic modes under X11, use the @code{vesa} or |
971 | 15a34c63 | bellard | the @code{cirrus} X11 driver. For optimal performances, use 16 bit |
972 | 15a34c63 | bellard | color depth in the guest and the host OS. |
973 | 1a084f3d | bellard | |
974 | e3371e62 | bellard | When using a 2.6 guest Linux kernel, you should add the option |
975 | e3371e62 | bellard | @code{clock=pit} on the kernel command line because the 2.6 Linux |
976 | e3371e62 | bellard | kernels make very strict real time clock checks by default that QEMU |
977 | e3371e62 | bellard | cannot simulate exactly. |
978 | e3371e62 | bellard | |
979 | 1a084f3d | bellard | @subsection Windows |
980 | 1a084f3d | bellard | |
981 | 1a084f3d | bellard | If you have a slow host, using Windows 95 is better as it gives the |
982 | 1a084f3d | bellard | best speed. Windows 2000 is also a good choice. |

985 | e3371e62 | bellard | |
986 | e3371e62 | bellard | QEMU emulates a Cirrus Logic GD5446 Video |
987 | 15a34c63 | bellard | card. All Windows versions starting from Windows 95 should recognize |
988 | 15a34c63 | bellard | and use this graphic card. For optimal performances, use 16 bit color |
989 | 15a34c63 | bellard | depth in the guest and the host OS. |
990 | 1a084f3d | bellard | |
991 | e3371e62 | bellard | @subsubsection CPU usage reduction |
992 | e3371e62 | bellard | |
993 | e3371e62 | bellard | Windows 9x does not correctly use the CPU HLT |
994 | 15a34c63 | bellard | instruction. The result is that it takes host CPU cycles even when |
995 | 15a34c63 | bellard | idle. You can install the utility from |
996 | 15a34c63 | bellard | @url{http://www.user.cityline.ru/~maxamn/amnhltm.zip} to solve this |
997 | 15a34c63 | bellard | problem. Note that no such tool is needed for NT, 2000 or XP. |

999 | e3371e62 | bellard | @subsubsection Windows 2000 disk full problems |
1000 | e3371e62 | bellard | |
1001 | e3371e62 | bellard | Currently (release 0.6.0) QEMU has a bug which gives a @code{disk |
1002 | e3371e62 | bellard | full} error during installation of some releases of Windows 2000. The |
1003 | e3371e62 | bellard | workaround is to stop QEMU as soon as you notice that your disk image |
1004 | e3371e62 | bellard | size is growing too fast (monitor it with @code{ls -ls}). Then |
1005 | e3371e62 | bellard | relaunch QEMU to continue the installation. If you still experience |
1006 | e3371e62 | bellard | the problem, relaunch QEMU again. |
1007 | e3371e62 | bellard | |
1008 | e3371e62 | bellard | Future QEMU releases are likely to correct this bug. |

1011 | e3371e62 | bellard | |
1012 | e3371e62 | bellard | Some releases of Windows XP install correctly but give a security |

1017 | e3371e62 | bellard | @end example |
1018 | e3371e62 | bellard | The only known workaround is to boot in Safe mode |

1129 | 1f673135 | bellard | In order to launch a Linux process, QEMU needs the process executable |
1130 | 1f673135 | bellard | itself and all the target (x86) dynamic libraries used by it. |
1131 | 386405f7 | bellard | |
1132 | 1f673135 | bellard | @itemize |
1133 | 386405f7 | bellard | |
1134 | 1f673135 | bellard | @item On x86, you can just try to launch any process by using the native |
1135 | 1f673135 | bellard | libraries: |
1136 | 386405f7 | bellard | |
1137 | 1f673135 | bellard | @example |
1138 | 1f673135 | bellard | qemu-i386 -L / /bin/ls |
1139 | 1f673135 | bellard | @end example |
1140 | 386405f7 | bellard | |
1141 | 1f673135 | bellard | @code{-L /} tells that the x86 dynamic linker must be searched with a |
1142 | 1f673135 | bellard | @file{/} prefix. |
1143 | 386405f7 | bellard | |
1144 | 1f673135 | bellard | @item Since QEMU is also a linux process, you can launch qemu with qemu (NOTE: you can only do that if you compiled QEMU from the sources): |
1145 | 386405f7 | bellard | |
1146 | 1f673135 | bellard | @example |
1147 | 1f673135 | bellard | qemu-i386 -L / qemu-i386 -L / /bin/ls |
1148 | 1f673135 | bellard | @end example |
1149 | 386405f7 | bellard | |
1150 | 1f673135 | bellard | @item On non x86 CPUs, you need first to download at least an x86 glibc |
1151 | 1f673135 | bellard | (@file{qemu-runtime-i386-XXX-.tar.gz} on the QEMU web page). Ensure that |
1152 | 1f673135 | bellard | @code{LD_LIBRARY_PATH} is not set: |
1153 | df0f11a0 | bellard | |
1154 | 1f673135 | bellard | @example |
1155 | 1f673135 | bellard | unset LD_LIBRARY_PATH |
1156 | 1f673135 | bellard | @end example |
1157 | 1eb87257 | bellard | |
1158 | 1f673135 | bellard | Then you can launch the precompiled @file{ls} x86 executable: |
1159 | 1eb87257 | bellard | |
1160 | 1f673135 | bellard | @example |
1161 | 1f673135 | bellard | qemu-i386 tests/i386/ls |
1162 | 1f673135 | bellard | @end example |
1163 | 1f673135 | bellard | You can look at @file{qemu-binfmt-conf.sh} so that |
1164 | 1f673135 | bellard | QEMU is automatically launched by the Linux kernel when you try to |
1165 | 1f673135 | bellard | launch x86 executables. It requires the @code{binfmt_misc} module in the |
1166 | 1f673135 | bellard | Linux kernel. |
1167 | 1eb87257 | bellard | |
1168 | 1f673135 | bellard | @item The x86 version of QEMU is also included. You can try weird things such as: |
1169 | 1f673135 | bellard | @example |
1170 | 1f673135 | bellard | qemu-i386 /usr/local/qemu-i386/bin/qemu-i386 /usr/local/qemu-i386/bin/ls-i386 |
1171 | 1f673135 | bellard | @end example |

1178 | 386405f7 | bellard | |
1179 | 1f673135 | bellard | @item Ensure that you have a working QEMU with the x86 glibc |
1180 | 1f673135 | bellard | distribution (see previous section). In order to verify it, you must be |
1181 | 1f673135 | bellard | able to do: |
1182 | 386405f7 | bellard | |
1183 | 1f673135 | bellard | @example |
1184 | 1f673135 | bellard | qemu-i386 /usr/local/qemu-i386/bin/ls-i386 |
1185 | 1f673135 | bellard | @end example |
1186 | 386405f7 | bellard | |
1187 | 1f673135 | bellard | @item Download the binary x86 Wine install |
1188 | 1f673135 | bellard | (@file{qemu-XXX-i386-wine.tar.gz} on the QEMU web page). |
1189 | 386405f7 | bellard | |
1190 | 1f673135 | bellard | @item Configure Wine on your account. Look at the provided script |
1191 | 1f673135 | bellard | @file{/usr/local/qemu-i386/bin/wine-conf.sh}. Your previous |

1193 | 386405f7 | bellard | |
1194 | 1f673135 | bellard | @item Then you can try the example @file{putty.exe}: |
1195 | 386405f7 | bellard | |
1196 | 1f673135 | bellard | @example |
1197 | 1f673135 | bellard | qemu-i386 /usr/local/qemu-i386/wine/bin/wine /usr/local/qemu-i386/wine/c/Program\ Files/putty.exe |
