Why does Windows 7 not supported?

[fenglei]

Why can't temu support win7?Not including the matter of system
driver,this version of qemu seems to be the matter.But why?As a whole
system emulator,does qemu 0.9.1 miss sth. to run win7?

Dear fenglei,

You can start win7 in qemu 0.9.1 but not in temu, because guest drivers in temu only for  winxp. But we have beta-version guest drivers in win7. If you have win7 qemu image then could you upload it in some filestore and to give me a link. I can test this driver and if it will work i can send it to you or upload in web-site.

Thanks,
Alex

Hi,
Does QEMU 0.9.1 is able to run Windows 7? On my machine the
installation has failed. This is without even trying TEMU. If yes,
please send me the hardware details of the machine which was able to
do so.
Thanks,
Amir

I don't think so.I have even tried to install Windows 7 by using ghost clone on qemu 0.9.1.The installation is OK.But I can never start it.

Thanks,

Fenglei

Hi,

Do you think I can get that Windows 7 driver for TEMU? And if so, would it support TEMU 1.0?

Thank you!

To my knowledge, no one has yet succeeded in getting Windows 7 to boot
properly under TEMU, a limitation which is shared by the older version
of QEMU on which TEMU is based. More recent versions of QEMU can boot
Windows 7 properly, but when I tried to do a bisection I didn't find
an obvious candidate fix that could be backported, suggesting that the
problem is something like timing.

As a hardware-level emulator, no special driver is supposed to be
required for TEMU to boot an operating system (which is why the
problem described in the previous paragraph is unexpected and
considered a bug). So I presume that by a "driver" you referring to
the "guest driver" which TEMU uses to get high-level information like
the list of running processes out of the machine. The TEMU guest
driver originally written for Windows XP uses mostly documented
interfaces, so it should be portable to later Windows versions fairly
straightforwardly. If I remember correctly, Alex Bazhanyuk succeeded
in getting it to compile against the Windows 7 driver development kit,
but couldn't test it because of the problem mentioned in the previous
paragraph. So while it might be straightforward for you to either
reproduce his work or get a copy from him, I think that doing so would
be futile without a fix for the booting problem.

Hope this helps,
