[Qemu-devel] Project: qemu OS zoo

[Stefano Marinelli]

Hello everybody. For a project (and, above all, for personal interest)
I'll be installing all the existing Operating System into Virtual
Machines. The target is to provide hd images ready-to-boot and to
customize (using the COW) to students and researchers. The project will
involve all the free systems (Linux, *BSD, Reactos, etc) as well as
the non-free ones (dos, windows (in several versions), etc.). So I'm
going to write reports of my results.
Most of the installations will be done on my iBook G4 (with Gentoo
Linux) and an x86 (faster with qemu). I'll also provide screenshots,
that could be useful to show the power of qemu to the world.
Hope to get good results with a lot of oses (and some gdb dumps for the
non-working ones).

How do you want to distribute these images?  (Hint:  See recent discussion
about a DOS floppy image with non-free software preinstalled and especially
Jean-Michel's comments.)

Thanks for the hint, I'll have a look. Anyway we can install (by
license, I'm talking about Microsoft OSes ) on any machine we want 
(inside the department). Of course I won't be able to distribute freely 
those images, but I'll have a look at the discussion.

Of course, I will distribute freely all the other installations.

Hi,

You might be careful, although win2k and winXP can be installed, there seems 
to be some bugs which prevents few programs running inside the emulation (2 
examples: try the Wordpad in WinXP and try Partition Magic - both fail 
immediately).

Also the network part got quite few problems by itself (by default WinXP 
doesn't detect the card and it seems it doesn't have the ne2k driver or 
something - thats without Renzo's patch)..

Good Luck,
Hetz

Do you have these problems with the latest release ? Now that these OSes 
can be launched I hope it will be easier to debug.

There are still problems in win95/win98 for the hardware probe, although 
with my latest patches for self modifying code it works better. The 
hardware probe problem should explain the impression of slowness in 
win95/win98: the timers run about 10 times slower, so all the graphical 
animations are slowed down by this factor - hopefully QEMU itself is not 
so slow !

[Qemu-devel] QEMU and win98se

[Grzegorz Kulewski]

Hi,

I had two problems with "current" cvs in recent week:

1. Win98se install caused qemu to crash because of sigsegv near the 
beginning of graphic part. (How can I debug that? Should I apply any 
special patches to qemu for win98 to work? Should I disable something in 
qemu's configure?)

2. After switching between qemu window and xterm to type something into 
the command line (or what is its name?) and then switching back i got "-" 
signs for enter and nothing for other keys in qemu (running win98se dos). 
Only closing qemu helped. Why is that? (I just wanted to change cdrom to 
win98se instalation cd.)


Thanks in advance,

Grzegorz Kulewski

With the CVS version running (with the sb16 disabled patch only) I don't see 
network card at all (it skips it when installing)

I don't think it's slow, but it seems that the graphics themselves are slow. 
Is the SDL using all X acceleration? (the XMAME guys for example are using 
the Xv extention to have hardware accelerated graphics when running MAME 
roms)...

Thanks,
Hetz

Xv is only useful if you want the graphic card to do scaling for you.
Moreover, for QEMU, it's only interesting if the card exports a RGB visual
for you (which is the case of the NVIDIA drivers but not, last time I
checked, on some ATI drivers in XFree).

If you display the graphic 'as is', I do not see why Xv should be faster
than plain XShm.

Renzo made a patch for it, maybe it was applied.
Can anyone confirm?

Best regards,

qemu IS fast, even on PowerPC. I have several x86 and PPC machines, and
I must admit that on x86 it goes REALLY faster than on PPC. Anyway the
graphical problem slows really much. For example, the installation of
Reactos is fast, but when you open the "Start" menu, it "grows" slowly.
Reactos on Bochs (using MacOS) took about 20 minutes to install...never
reached a boot due to the slowness.

[Qemu-devel] Win2K runs perfectly

[Matthew Mastracci]

Using only the patch I posted earlier, Windows 2000 is running perfectly
using the latest source release.  I accidentally left it running all day
with the 3D maze screensaver going, but it managed to survive.  :)

You can see my full-color screenshots here:

And there is another nice (practical) aspect of it as well. It can be
used to compile binaries for other platforms by using the virtual
machines as virtual compile farm (most of the times the speed isn't the
problem, but more the number of platforms, when using a compilefarm).

Sure. Another example: an Operating System course at university. It's
easier to teach about the different oses having the possibility to show
students how they work. Moreover, if you have enough resources, you can
turn them into "root"!
