[HVM][SVM] Check if SVM is disabled by the BIOS before enabling it.

Newer BIOS implementations will be able to disable the SVM feature,
although an additional test of an MSR (VMCR 0xC0010114 bit 4) is
necessary (set equals disabled). Bit 4 of MSR 0xc0010114 returns 0
(SVM enabled) on machines with older BIOS' without the SVM disable
feature support.

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

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