  879 +When using a 2.6 guest Linux kernel, you should add the option

  904 +@subsubsection Windows 2000 disk full problems
  905 +
  906 +Currently (release 0.6.0) QEMU has a bug which gives a @code{disk
  907 +full} error during installation of some releases of Windows 2000. The
  908 +workaround is to stop QEMU as soon as you notice that your disk image
  909 +size is growing too fast (monitor it with @code{ls -ls}). Then
  910 +relaunch QEMU to continue the installation. If you still experience
  911 +the problem, relaunch QEMU again.
  912 +
  913 +Future QEMU releases are likely to correct this bug.

  915 +@subsubsection Windows XP security problems

  917 +Some releases of Windows XP install correctly but give a security
  918 +error when booting:
  919 +@example
  920 +A problem is preventing Windows from accurately checking the
  921 +license for this computer. Error code: 0x800703e6.
  922 +@end example
  923 +The only known workaround is to boot in Safe mode
  924 +without networking support.
  925 +
  926 +Future QEMU releases are likely to correct this bug.
