kaf24@1070 1 XEN NOTICE
kaf24@1070 2 ==========
kaf24@1070 3
kaf24@1070 4 This copyright does *not* cover guest operating systems that use
kaf24@1070 5 Xen services via normal hypercalls - this is merely considered normal
kaf24@1070 6 use of Xen, and does *not* fall under the heading of "derived work".
kaf24@1070 7 Also note that the GPL below is copyrighted by the Free Software
kaf24@1070 8 Foundation, but the instance of code that it refers to (the Xen
kaf24@1070 9 virtual machine monitor) is copyrighted by me and others who actually
kaf24@1070 10 wrote it.
kaf24@1070 11
kaf24@1070 12 Further note that the guest-OS interfacing header files, which
kaf24@1070 13 includes all files within the subdirectory include/hypervisor-ifs, are
kaf24@1070 14 *not* covered by the GPL but by a much weaker license:
kaf24@1070 15 include/hypervisor-ifs/COPYING
kaf24@1070 16
kaf24@1070 17 Also note that the only valid version of the GPL as far as Xen is
kaf24@1070 18 concerned is _this_ particular version of the license (i.e., *only*
kaf24@1070 19 v2, not v2.2 or v3.x or whatever), unless explicitly otherwise
kaf24@1070 20 stated.

kaf24@804 26 GNU GENERAL PUBLIC LICENSE
kaf24@804 27 Version 2, June 1991
kaf24@804 28
kaf24@804 29 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
kaf24@804 30 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
kaf24@804 31 Everyone is permitted to copy and distribute verbatim copies
kaf24@804 32 of this license document, but changing it is not allowed.
kaf24@804 33
kaf24@804 34 Preamble
kaf24@804 35
kaf24@804 36 The licenses for most software are designed to take away your
kaf24@804 37 freedom to share and change it. By contrast, the GNU General Public
kaf24@804 38 License is intended to guarantee your freedom to share and change free
kaf24@804 39 software--to make sure the software is free for all its users. This
kaf24@804 40 General Public License applies to most of the Free Software
kaf24@804 41 Foundation's software and to any other program whose authors commit to
kaf24@804 42 using it. (Some other Free Software Foundation software is covered by
kaf24@804 43 the GNU Library General Public License instead.) You can apply it to
kaf24@804 44 your programs, too.
kaf24@804 45
kaf24@804 46 When we speak of free software, we are referring to freedom, not
kaf24@804 47 price. Our General Public Licenses are designed to make sure that you
kaf24@804 48 have the freedom to distribute copies of free software (and charge for
kaf24@804 49 this service if you wish), that you receive source code or can get it
kaf24@804 50 if you want it, that you can change the software or use pieces of it
kaf24@804 51 in new free programs; and that you know you can do these things.
kaf24@804 52
kaf24@804 53 To protect your rights, we need to make restrictions that forbid
kaf24@804 54 anyone to deny you these rights or to ask you to surrender the rights.
kaf24@804 55 These restrictions translate to certain responsibilities for you if you
kaf24@804 56 distribute copies of the software, or if you modify it.
kaf24@804 57
kaf24@804 58 For example, if you distribute copies of such a program, whether
kaf24@804 59 gratis or for a fee, you must give the recipients all the rights that
kaf24@804 60 you have. You must make sure that they, too, receive or can get the
kaf24@804 61 source code. And you must show them these terms so they know their
kaf24@804 62 rights.
kaf24@804 63
kaf24@804 64 We protect your rights with two steps: (1) copyright the software, and
kaf24@804 65 (2) offer you this license which gives you legal permission to copy,
kaf24@804 66 distribute and/or modify the software.
kaf24@804 67
kaf24@804 68 Also, for each author's protection and ours, we want to make certain
kaf24@804 69 that everyone understands that there is no warranty for this free
kaf24@804 70 software. If the software is modified by someone else and passed on, we
kaf24@804 71 want its recipients to know that what they have is not the original, so
kaf24@804 72 that any problems introduced by others will not reflect on the original
kaf24@804 73 authors' reputations.
kaf24@804 74
kaf24@804 75 Finally, any free program is threatened constantly by software
kaf24@804 76 patents. We wish to avoid the danger that redistributors of a free
kaf24@804 77 program will individually obtain patent licenses, in effect making the
kaf24@804 78 program proprietary. To prevent this, we have made it clear that any
kaf24@804 79 patent must be licensed for everyone's free use or not licensed at all.
kaf24@804 80
kaf24@804 81 The precise terms and conditions for copying, distribution and
kaf24@804 82 modification follow.
kaf24@804 83
kaf24@804 84 GNU GENERAL PUBLIC LICENSE
kaf24@804 85 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
kaf24@804 86
kaf24@804 87 0. This License applies to any program or other work which contains
kaf24@804 88 a notice placed by the copyright holder saying it may be distributed
kaf24@804 89 under the terms of this General Public License. The "Program", below,
kaf24@804 90 refers to any such program or work, and a "work based on the Program"
kaf24@804 91 means either the Program or any derivative work under copyright law:
kaf24@804 92 that is to say, a work containing the Program or a portion of it,
kaf24@804 93 either verbatim or with modifications and/or translated into another
kaf24@804 94 language. (Hereinafter, translation is included without limitation in
kaf24@804 95 the term "modification".) Each licensee is addressed as "you".
kaf24@804 96
kaf24@804 97 Activities other than copying, distribution and modification are not
kaf24@804 98 covered by this License; they are outside its scope. The act of
kaf24@804 99 running the Program is not restricted, and the output from the Program
kaf24@804 100 is covered only if its contents constitute a work based on the
kaf24@804 101 Program (independent of having been made by running the Program).
kaf24@804 102 Whether that is true depends on what the Program does.
kaf24@804 103
kaf24@804 104 1. You may copy and distribute verbatim copies of the Program's
kaf24@804 105 source code as you receive it, in any medium, provided that you
kaf24@804 106 conspicuously and appropriately publish on each copy an appropriate
kaf24@804 107 copyright notice and disclaimer of warranty; keep intact all the
kaf24@804 108 notices that refer to this License and to the absence of any warranty;
kaf24@804 109 and give any other recipients of the Program a copy of this License
kaf24@804 110 along with the Program.
kaf24@804 111
kaf24@804 112 You may charge a fee for the physical act of transferring a copy, and
kaf24@804 113 you may at your option offer warranty protection in exchange for a fee.
kaf24@804 114
kaf24@804 115 2. You may modify your copy or copies of the Program or any portion
kaf24@804 116 of it, thus forming a work based on the Program, and copy and
kaf24@804 117 distribute such modifications or work under the terms of Section 1
kaf24@804 118 above, provided that you also meet all of these conditions:
kaf24@804 119
kaf24@804 120 a) You must cause the modified files to carry prominent notices
kaf24@804 121 stating that you changed the files and the date of any change.
kaf24@804 122
kaf24@804 123 b) You must cause any work that you distribute or publish, that in
kaf24@804 124 whole or in part contains or is derived from the Program or any
kaf24@804 125 part thereof, to be licensed as a whole at no charge to all third
kaf24@804 126 parties under the terms of this License.
kaf24@804 127
kaf24@804 128 c) If the modified program normally reads commands interactively
kaf24@804 129 when run, you must cause it, when started running for such
kaf24@804 130 interactive use in the most ordinary way, to print or display an
kaf24@804 131 announcement including an appropriate copyright notice and a
kaf24@804 132 notice that there is no warranty (or else, saying that you provide
kaf24@804 133 a warranty) and that users may redistribute the program under
kaf24@804 134 these conditions, and telling the user how to view a copy of this
kaf24@804 135 License. (Exception: if the Program itself is interactive but
kaf24@804 136 does not normally print such an announcement, your work based on
kaf24@804 137 the Program is not required to print an announcement.)
kaf24@804 138
kaf24@804 139 These requirements apply to the modified work as a whole. If
kaf24@804 140 identifiable sections of that work are not derived from the Program,
kaf24@804 141 and can be reasonably considered independent and separate works in
kaf24@804 142 themselves, then this License, and its terms, do not apply to those
kaf24@804 143 sections when you distribute them as separate works. But when you
kaf24@804 144 distribute the same sections as part of a whole which is a work based
kaf24@804 145 on the Program, the distribution of the whole must be on the terms of
kaf24@804 146 this License, whose permissions for other licensees extend to the
kaf24@804 147 entire whole, and thus to each and every part regardless of who wrote it.
kaf24@804 148
kaf24@804 149 Thus, it is not the intent of this section to claim rights or contest
kaf24@804 150 your rights to work written entirely by you; rather, the intent is to
kaf24@804 151 exercise the right to control the distribution of derivative or
kaf24@804 152 collective works based on the Program.
kaf24@804 153
kaf24@804 154 In addition, mere aggregation of another work not based on the Program
kaf24@804 155 with the Program (or with a work based on the Program) on a volume of
kaf24@804 156 a storage or distribution medium does not bring the other work under
kaf24@804 157 the scope of this License.
kaf24@804 158
kaf24@804 159 3. You may copy and distribute the Program (or a work based on it,
kaf24@804 160 under Section 2) in object code or executable form under the terms of
kaf24@804 161 Sections 1 and 2 above provided that you also do one of the following:
kaf24@804 162
kaf24@804 163 a) Accompany it with the complete corresponding machine-readable
kaf24@804 164 source code, which must be distributed under the terms of Sections
kaf24@804 165 1 and 2 above on a medium customarily used for software interchange; or,
kaf24@804 166
kaf24@804 167 b) Accompany it with a written offer, valid for at least three
kaf24@804 168 years, to give any third party, for a charge no more than your
kaf24@804 169 cost of physically performing source distribution, a complete
kaf24@804 170 machine-readable copy of the corresponding source code, to be
kaf24@804 171 distributed under the terms of Sections 1 and 2 above on a medium
kaf24@804 172 customarily used for software interchange; or,
kaf24@804 173
kaf24@804 174 c) Accompany it with the information you received as to the offer
kaf24@804 175 to distribute corresponding source code. (This alternative is
kaf24@804 176 allowed only for noncommercial distribution and only if you
kaf24@804 177 received the program in object code or executable form with such
kaf24@804 178 an offer, in accord with Subsection b above.)
kaf24@804 179
kaf24@804 180 The source code for a work means the preferred form of the work for
kaf24@804 181 making modifications to it. For an executable work, complete source
kaf24@804 182 code means all the source code for all modules it contains, plus any
kaf24@804 183 associated interface definition files, plus the scripts used to
kaf24@804 184 control compilation and installation of the executable. However, as a
kaf24@804 185 special exception, the source code distributed need not include
kaf24@804 186 anything that is normally distributed (in either source or binary
kaf24@804 187 form) with the major components (compiler, kernel, and so on) of the
kaf24@804 188 operating system on which the executable runs, unless that component
kaf24@804 189 itself accompanies the executable.
kaf24@804 190
kaf24@804 191 If distribution of executable or object code is made by offering
kaf24@804 192 access to copy from a designated place, then offering equivalent
kaf24@804 193 access to copy the source code from the same place counts as
kaf24@804 194 distribution of the source code, even though third parties are not
kaf24@804 195 compelled to copy the source along with the object code.
kaf24@804 196
kaf24@804 197 4. You may not copy, modify, sublicense, or distribute the Program
kaf24@804 198 except as expressly provided under this License. Any attempt
kaf24@804 199 otherwise to copy, modify, sublicense or distribute the Program is
kaf24@804 200 void, and will automatically terminate your rights under this License.
kaf24@804 201 However, parties who have received copies, or rights, from you under
kaf24@804 202 this License will not have their licenses terminated so long as such
kaf24@804 203 parties remain in full compliance.
kaf24@804 204
kaf24@804 205 5. You are not required to accept this License, since you have not
kaf24@804 206 signed it. However, nothing else grants you permission to modify or
kaf24@804 207 distribute the Program or its derivative works. These actions are
kaf24@804 208 prohibited by law if you do not accept this License. Therefore, by
kaf24@804 209 modifying or distributing the Program (or any work based on the
kaf24@804 210 Program), you indicate your acceptance of this License to do so, and
kaf24@804 211 all its terms and conditions for copying, distributing or modifying
kaf24@804 212 the Program or works based on it.
kaf24@804 213
kaf24@804 214 6. Each time you redistribute the Program (or any work based on the
kaf24@804 215 Program), the recipient automatically receives a license from the
kaf24@804 216 original licensor to copy, distribute or modify the Program subject to
kaf24@804 217 these terms and conditions. You may not impose any further
kaf24@804 218 restrictions on the recipients' exercise of the rights granted herein.
kaf24@804 219 You are not responsible for enforcing compliance by third parties to
kaf24@804 220 this License.
kaf24@804 221
kaf24@804 222 7. If, as a consequence of a court judgment or allegation of patent
kaf24@804 223 infringement or for any other reason (not limited to patent issues),
kaf24@804 224 conditions are imposed on you (whether by court order, agreement or
kaf24@804 225 otherwise) that contradict the conditions of this License, they do not
kaf24@804 226 excuse you from the conditions of this License. If you cannot
kaf24@804 227 distribute so as to satisfy simultaneously your obligations under this
kaf24@804 228 License and any other pertinent obligations, then as a consequence you
kaf24@804 229 may not distribute the Program at all. For example, if a patent
kaf24@804 230 license would not permit royalty-free redistribution of the Program by
kaf24@804 231 all those who receive copies directly or indirectly through you, then
kaf24@804 232 the only way you could satisfy both it and this License would be to
kaf24@804 233 refrain entirely from distribution of the Program.
kaf24@804 234
kaf24@804 235 If any portion of this section is held invalid or unenforceable under
kaf24@804 236 any particular circumstance, the balance of the section is intended to
kaf24@804 237 apply and the section as a whole is intended to apply in other
kaf24@804 238 circumstances.
kaf24@804 239
kaf24@804 240 It is not the purpose of this section to induce you to infringe any
kaf24@804 241 patents or other property right claims or to contest validity of any
kaf24@804 242 such claims; this section has the sole purpose of protecting the
kaf24@804 243 integrity of the free software distribution system, which is
kaf24@804 244 implemented by public license practices. Many people have made
kaf24@804 245 generous contributions to the wide range of software distributed
kaf24@804 246 through that system in reliance on consistent application of that
kaf24@804 247 system; it is up to the author/donor to decide if he or she is willing
kaf24@804 248 to distribute software through any other system and a licensee cannot
kaf24@804 249 impose that choice.
kaf24@804 250
kaf24@804 251 This section is intended to make thoroughly clear what is believed to
kaf24@804 252 be a consequence of the rest of this License.
kaf24@804 253
kaf24@804 254 8. If the distribution and/or use of the Program is restricted in
kaf24@804 255 certain countries either by patents or by copyrighted interfaces, the
kaf24@804 256 original copyright holder who places the Program under this License
kaf24@804 257 may add an explicit geographical distribution limitation excluding
kaf24@804 258 those countries, so that distribution is permitted only in or among
kaf24@804 259 countries not thus excluded. In such case, this License incorporates
kaf24@804 260 the limitation as if written in the body of this License.
kaf24@804 261
kaf24@804 262 9. The Free Software Foundation may publish revised and/or new versions
kaf24@804 263 of the General Public License from time to time. Such new versions will
kaf24@804 264 be similar in spirit to the present version, but may differ in detail to
kaf24@804 265 address new problems or concerns.
kaf24@804 266
kaf24@804 267 Each version is given a distinguishing version number. If the Program
kaf24@804 268 specifies a version number of this License which applies to it and "any
kaf24@804 269 later version", you have the option of following the terms and conditions
kaf24@804 270 either of that version or of any later version published by the Free
kaf24@804 271 Software Foundation. If the Program does not specify a version number of
kaf24@804 272 this License, you may choose any version ever published by the Free Software
kaf24@804 273 Foundation.
kaf24@804 274
kaf24@804 275 10. If you wish to incorporate parts of the Program into other free
kaf24@804 276 programs whose distribution conditions are different, write to the author
kaf24@804 277 to ask for permission. For software which is copyrighted by the Free
kaf24@804 278 Software Foundation, write to the Free Software Foundation; we sometimes
kaf24@804 279 make exceptions for this. Our decision will be guided by the two goals
kaf24@804 280 of preserving the free status of all derivatives of our free software and
kaf24@804 281 of promoting the sharing and reuse of software generally.
kaf24@804 282
kaf24@804 283 NO WARRANTY
kaf24@804 284
kaf24@804 285 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
kaf24@804 286 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
kaf24@804 287 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
kaf24@804 288 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
kaf24@804 289 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
kaf24@804 290 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
kaf24@804 291 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
kaf24@804 292 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
kaf24@804 293 REPAIR OR CORRECTION.
kaf24@804 294
kaf24@804 295 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
kaf24@804 296 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
kaf24@804 297 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
kaf24@804 298 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
kaf24@804 299 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
kaf24@804 300 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
kaf24@804 301 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
kaf24@804 302 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
kaf24@804 303 POSSIBILITY OF SUCH DAMAGES.
kaf24@804 304
kaf24@804 305 END OF TERMS AND CONDITIONS
kaf24@804 306
kaf24@804 307 How to Apply These Terms to Your New Programs
kaf24@804 308
kaf24@804 309 If you develop a new program, and you want it to be of the greatest
kaf24@804 310 possible use to the public, the best way to achieve this is to make it
kaf24@804 311 free software which everyone can redistribute and change under these terms.
kaf24@804 312
kaf24@804 313 To do so, attach the following notices to the program. It is safest
kaf24@804 314 to attach them to the start of each source file to most effectively
kaf24@804 315 convey the exclusion of warranty; and each file should have at least
kaf24@804 316 the "copyright" line and a pointer to where the full notice is found.
kaf24@804 317
kaf24@804 318 <one line to give the program's name and a brief idea of what it does.>
kaf24@804 319 Copyright (C) <year> <name of author>

kaf24@804 321 This program is free software; you can redistribute it and/or modify
kaf24@804 322 it under the terms of the GNU General Public License as published by

kaf24@804 329 GNU General Public License for more details.
kaf24@804 330
kaf24@804 331 You should have received a copy of the GNU General Public License

kaf24@804 335
kaf24@804 336 Also add information on how to contact you by electronic and paper mail.
kaf24@804 337
kaf24@804 338 If the program is interactive, make it output a short notice like this
kaf24@804 339 when it starts in an interactive mode:
kaf24@804 340
kaf24@804 341 Gnomovision version 69, Copyright (C) year name of author
kaf24@804 342 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
kaf24@804 343 This is free software, and you are welcome to redistribute it
kaf24@804 344 under certain conditions; type `show c' for details.
kaf24@804 345
kaf24@804 346 The hypothetical commands `show w' and `show c' should show the appropriate

kaf24@804 361 This General Public License does not permit incorporating your program into
kaf24@804 362 proprietary programs. If your program is a subroutine library, you may
kaf24@804 363 consider it more useful to permit linking proprietary applications with the
kaf24@804 364 library. If this is what you want to do, use the GNU Library General
kaf24@804 365 Public License instead of this License.
