I had it successfully tested with WinXP as guest on WinXP and Gentoo
2005.0 (with and without kqemu and with VNC) hosts. Hibernate works
fine. Congratulation !!!

Hi -
For anyone running Windows 2000 on Qemu, I've developed a fix that
makes APM - and therefore Windows 2000 shutdown - correctly 'power
off' (i.e. close) Qemu.
I needed to patch the BIOS - which didn't implement the APM 1.2 16-bit
protected mode interface that Windows 2000 apparently requires.
Afterwards, as my Windows 2000 installation didn't have the APM driver
installed, I simply needed to install it by going Control Panel =>
Add/Remove Hardware & Next => Add/Troubleshoot a device => Add a new
device & Next => No, I want to select the hardware from a list & Next
=> NT Apm/Legacy Support & Next => Next (again) a few times.
Afterwards, I did Control Panel => Power Options, chose the APM tab
and made sure the Advanced Power Management support checkbox was
ticked. I also chose the Hibernate tab and enabled Hibernate Support
too. After rebooting, Windows 2000 now correctly instructs Qemu to
shutdown at the appropriate moment. No patches to Qemu were required.
What doesn't work yet is Standby and Suspend, although I've
generalised the APM Bios to support both of them. When attempting
Standby (which doesn't always appear as an option - a problem I'm
aware of), Windows tries to go into Standby but then reports that "the
device driver for the device is preventing this machine from entering
standby. Please close all applications and try again. If the problem
persists, you may need to update this driver." I don't know why this
should be. By contrast, Suspend doesn't ever appear as an option - but
it would be nice to make this trigger the Qemu savevm/loadvm facility.
You can find the Bios source patch as well as a precompiled
patched-binary bios (for those who don't want to download the Bochs
source) at
http://www.praguespringpeople.org/Struan/Software/BochsBIOS/. Simply
copy bios.bin-patchedAPM1.2 over your /usr/local/share/qemu/bios.bin
(or better over pc-bios/bios.bin in your Qemu source directory and
then do 'make install').
