Hi List...

I’m a developer/CRM consultor from Colombia (South
America), and I’m quite interested in QEMU project due
to my job requirements.

 

I always have to switch among a lot of environments on
costumers consultancy, several running Windows 2000
environments and AS400, but most of all W2k, none of
all under W9x….

 

My company provided me with a DELL Latitude Laptop
(512M RAM, PIII 850 Mhz, running Win XP SP2)

 

I found QEMU project fits perfectly in my needs, and
I’ve spent like a week trying to install w2k onto QEMU
win32 porting but, it always starts the process,
format the hda hard disk, copy the files, restart and
tries to finish the installation process, but it hangs
up when the progress bar is 100%, even yesterday I
though that was a time thing, and I decided spent all
the night (around 10 hours!) in the installation
process; all the night QEMU was hung up!!!

 

I probed with the following versions of QEMU Win 32….

 

QemuInstall-0.6.1-fix.exe (Nov 15)
 
QemuInstall-20041202-vnc.exe (Dec 2)
 
QemuInstall-20041213.exe (Dec 13)

I have researched on internet and I found that there
are some problems with that kind of install, however,
no one mentioned my problem, but I’ve made the changes
they suggest and I get the same…...  
 
Even more, I’ve tried BOCHS project, but using it I
can’t reach the installation phase I’ve commented
here.  
 
So that, I’ve got some questions for you...
 
1.    Do you have any suggestions in order to get W2K
installed and working correctly onto QEMU?
2.    Can you refer me SUCESSFULLY and step-by-step
installations of Win2k under QEMU for windows in Win
XP (or likely)?
3.    Is there a way to emulate an AS 400 System using
QEMU or other software?
4.    Do I need to do some tricks to bypass that w2k
install phase?
 
Please help me or refer me someone that can help me as
faster as you can…
 
Thanks in advance. Regards from Colombia.

Is this the diskfull thing, or could it be linked to?
There is a patch that need testing for the diskfull issue, maybe you can
try.

IOW, you try a w2k guest on top of a wxp host?

It depends on what version you use. Win2k with service pack 1 seems to work fine
here. But Win2k sp3 is pretty hard to install.

I use a Linux host tho. 2.4 kernel.

what is AS 400?

Did you close qemu at that point and then restart it (with the same options) ?
Can't guarrentee it will work, but sometimes it seems to help.

For the paranoid, you can use savevm in the qemu monitor before you close it,
and restart it with the -snapshot option. If, say, installation decides to restart
from the very beginning, you can just quit qemu again (snapshot will prevent
disk from being changed) and then you can use -loadvm option to load the
saved vm state, which will put you back to where you left off.

AS/400 is an IBM operating system for mid-range servers that runs on
POWER chips.  As I remember, all processes run in a single address
space to eliminate TLB flushes in context switches, but page
permissions get changed by the kernel when switching between
processes.  I believe I was reading about the history of POWER/PPC and
learned that the POWER/PPC family encompases 3 overlapping instriction
sets, one of which is required for AS/400.

I believe the 604e and similar chips do not implement some of the
functions required for AS/400.  I'm not sure about G3s, but I doubt
it.  I believe QEMU emulates something G3-ish, so I don't think AS/400
will run on the QEMU-emulated PPC CPU.  However, I could very well be
wrong.

I just did a quick search, and didn't find anything useful about
AS/400.  IBM has something called OS/400 (now called i5/OS), but that
looks like something in the OS/370, OS/390 family.  I don't think
AS/400 is in the OS/370 family, but I could be wrong.  AS/400 may have
been phased out.

It would be really cool if eventually QEMU could emulate IBM POWER
based servers well enough to run IBM's hypervisor.  The hypervisor
virtualizes the hardware for the operating system(s) proper and
provides resource partitioning.  Imagine VMware slimmed down and
ported to run on the bare hardware so it doesn't need a host operating
system and you've got a hypervisor.  Generally, the hypervisor
logically partitions resources and runs a seperate operating system
inside each partition.  The Xen project is developing a hypervisor for
x86 hardware, but it requires minor patching of the guest kernels to
avoid certain instructions.  (VMware works very similarly to Xen, but
VMware scans and dynamically patches code at runtime.)  Anyway, being
able to play around with (emulated) high-end hardware that was
designed for hypervisors would be cool.

AS/400 run on regular RS64. I don't know much about RS64 but it seems to
be a regular 64 bits PPC with multithread feature (ie like
hyperthreading) and hypervisor capabilities.

One thing is POWER/RS64 are 64 bits CPU while Qemu-PPC emulates only 32
bits CPU for now.

AS400 is not in the mainframe (ie OS/370 & 390) family and the CPU and
design are very different.
One problem is to get detailed informations about the hardware in order
to emulate it.
In a other hand, the virtual devices seem not to be so complicated.

I don't think the hypervisor feature is really hard to emulate. It's a
kind of very simple MMU feature with OS partitions defined by their
physical memory address base and size. But you'll need a lot of memory
to be able to launch many OSes.
A first point would be to launch one OS using OF, RTAS and hypervisor
virtual devices but with only one LPAR.

IMHO, the main problem is then to emulate 64 bits PPC/Power and make
qemu safe and running well on 64 bits host then (maybe) emulate 64 bits
targets on 32 bits host, but this will be very slow if it ever work...
