Hi,
THIS IS NOT AN HTML OR IE PROBLEM! It's a bug in Qemus emulation.
Here is most likely the reason for some problems that newer Windows
versions (since IE 5.x) may have caused. It is not always obvious
that IE is the reason as it is often "hidden" inside other apps.
The bug does not appear in
Hi,
there is still a little problem with ne2000:
(1) when the vm is in stopped state packets are still received
(2) this can fill the receive buffer before savevm ...
(3) when restarting qemu with loadvm the buffer is still full
(4) the guest OS does not get an int, so it does not know that

Hi,
the following is stuff from qemu-xp and cannot directly be applied to the
qemu sources. Anyhow: you can see what I have done. As a result windows
displays the correct time. Also the poll() was a bit optimised. The timer
stuff was changed to get some cpu cycles back. On a system with low CPU

Hi,
my little qemu project (I name it qemu-xp and will report on it
later) has reached it's starting point. Unfortunately these
"preparations" are so interesting they might be helpfull for users.
Such an important but trivial thing is to make the clock in windows
go right (now also with speed-step
Please take the following as a compliment: After four weeks of
studying and refactoring the qemu code I found a second bug.
The 1st one was a missing ne2000 register, the second one lets
the rtc-clock loose ticks if the system is under load. Cool!
The author (Fabrice?) obviously did no want the ti

Please note: I will send the Async IO stuff later, see below.

Hi Andre
you suggested ...
While you are at it, have you considered using the LZO libraries
instead of zlib for compression/decompression speed? Sure, it won't
compress as much as zlib, but speed improvements should be noticeable.
... sorry. This is a misunderstanding.

THE FOLLOWING IS IMPORTANT (COMMENTS ARE WELCOME):
I will modifiy monitor.c to implement a "save" command. That command
will do:

The commands commit and savevm will be modified to give progress

Hi,
win2003 (and as you say win XP) does not detect the media change.
As a consequence the cached data gets not flushed (inside win).
The "change cd /dev/cdrom" sometimes caused a qemu crash for me.
So you probably found a bug. If nobody else solves the problem it
will stay on my list as a low pri

Hello,
although I will integrate this into my patchset this not a proposed patch

Hello dear readers,
as I found out qemu is quite stable and has acceptable performance. Using it you
could freeze legacy applications using a legacy OS like win 2003 or win XP. I am
talking of periods from 5 to 20 years! In a commercial environment it happens
frequently that you would like to acc

now my qemu evaluation is done, I had a deep look into the code and I can now
write my
documentation. What I wanted to find out was:
(1) Can qemu be used with the latest MS OS (e.g. Win2003) to run legacy
software under Linux?
Answer: yes it works fine and stable. Win2003 activat
