[Qemu-devel] Usermode networking for win32

[Qemu-devel] Usermode networking for win32

[Elefterios Stamatogiannakis]

  I've been playing with the idea of compiling (via mingw, sdl) user 
mode networking (slirp) under windows.

  Right now it compiles but when i try to run it, nothing happens.

  For anyone interested:

  http://www.dblab.ece.ntua.gr/~estama/qemu-slirp-win32.zip

  is my working source.

  The only changes are in the qemu/slirp directory and the
  qemu/i386-softmmu/config.mak

  the source is from todays cvs

  any suggestions appreciated because i'm mighty stuck.

  teris.

ps what i'm trying to do is to have a way to "autorun" live linux 
distributions under windows with networking enabled.
ps2 many many thanks to Fabrice and the rest of the guys.

In fact, if you look back through the archives, what you are trying to
do with autorunning live linux distros was my original reason for
suggesting addition of proxy networking to QEMU.

I'm glad someone finally has time to make it work (unlike me).

It needs to change vl.c to call select.

  Kazu i see... thanks.

  I just saw in a previous mail of yours that you are working on win32 
networking too.

  Are we duplicating effort?

  Maybe we should work together?

  thanks again.

Re: [Qemu-devel] Usermode networking for win32

[Stamatogiannakis Elefterios]

  I've managed to run qemu with slirp enabled on win32.

  It needed some more changes in slirp.c, vl.c (thanks kazu) in order to 
run, as well a "resolv.conf" file in the same directory as the 
executable (qemu.exe), that has the usual unix format.

  The problem right now is that the slax live cd which i'm testing it 
with, doesn't see at all the network card (ne2000). (there is no ne2000 
in dmesg, ifconfig shows only the loopback adapter).

  Any ideas why there is no network card? (with -user-net as an options 
of course)

  Kazu do you know if the entire poll section is needed in order to run 
slirp in vl.c? (i'm referring to /* poll any events */).

  thanks.

  teris.

ps The new source is at:
http://www.dblab.ece.ntua.gr/~estama/qemu-slirp-win32.zip
ps2 Sorry for the state of my changes (lots and lots of hardcoded 
changes). When (if) this works i'll polish it up and send it as a diff.

Yes, it needs.

It seems that my patch works. Here is my patch.

http://www.h7.dion.ne.jp/~qemu-win/download/qemu-0.5.5-slirp.patch.gz

It needs to refine it but I tested telnet, ftp, lynx in RedHat 7.2 on
Windows2000.

To make the program, apply this patch and ./configure --enable-slirp.

Then on GestOS,
modprobe ne irq=9 io=0x300
dhcpcd eth0              or                dhclient eth0

It takes time to get IP address from DHCP server. Then I can use those
programs.
I think it is the same for Morphix.

It needs to disable NTLM authentication on Windows2000 to telnet.

kazu

  Thanks Kazu. I'll take a look at your patch.

  I'll certainly learn from it.

  Kazu your patch does not seem to use closesocket at all when closing 
sockets.

  Qemu win32 networking works but creates sockets without closing them.

  It needs also to change the configure file because by default $mingw32 
disables slirp.

  teris.

ps Great work..

[Qemu-devel] SIGSEGV with WinXP PRO PL instalation (CVS)

[Grzegorz Kulewski]

Hi,

Using today (morning) CVS I tried to intall WinXP PRO PL. I was using this 
command line:

qemu -hda winxppropl.img -cdrom Pl_WinXP_Pro_ISO.iso -pci -cirrusvga -m 256


Installer finished first part of instalation and "reboted" "machine". It 
continued, asked me about key, ..., network setup and then was still doing 
something, but I do not know what because I was eating lunch. :-)

When I returned QEMU was not there and only 

QEMU 0.5.5 monitor - type 'help' for more information
(qemu) Naruszenie ochrony pamieci

appeared on the terminal. (This is Polish translation for SIGSEGV.)


Has anyone saw such problem?

Are the -pci and -cirrusvga options supposed to work with XP currently?

How can I debug it further? (What should I do with gdb because I do not 
know this debuger?)

Do I need anything to do after intalling QEMU in order to use -cirrusvga?

Why is message:

warning: could not open /dev/net/tun: no virtual network emulation
Could not configure '/dev/rtc' to have a 1024 Hz timer. This is not a 
fatal
error, but for better emulation accuracy either use a 2.6 host Linux 
kernel or
type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.

appearing on the screen althought I added this line to startup scripts 
years ago for mplayer. Strace shows that device is opened properly but 
ioctl fails (not supported). I am using 2.6.6-mm4 currently. The same 
problem is recently with mplayer, so I think that kernel people changed 
something...


Thanks in advance,

Grzegorz Kulewski

Thank you. I will look for where I can close socket.
