[Qemu-devel] Command line / invocation

[Sylvain Petreolle]

Hi all,

I noticed there is a problem in qemu invocation.

The help actually says we have to use "-boot [a|b|c|d]" to specify the disk to boot on.
This doesnt work, saying there is no such option.
Correct syntax seems to be "--boot", the same applies to --hda and --cdrom.

Do you want to change options to use a single hyphen or modify the help in the future ?

$ qemu -boot c -hda test
c: No such file or directory
C:\msys\1.0\home\syl\qemu_win32\qemu.exe: unknown option -- b
C:\msys\1.0\home\syl\qemu_win32\qemu.exe: unknown option -- o
C:\msys\1.0\home\syl\qemu_win32\qemu.exe: unknown option -- o
C:\msys\1.0\home\syl\qemu_win32\qemu.exe: unknown option -- t
qemu: could not open hard disk image 'c

Most programs tend to use a single hyphen for single letter switches, ie:

    cp -r foo bar

And double hyphens for full switches, ie:

    cp --recursive foo bar

And as in the case above, single letter switches are usually provided in
addition to full switches as shortcuts. Both are valid.

Maybe as QEMU gains more features, thought could be given to prioritise
which features actually warrant a single letter shortcut switch.

The boot option looks like an ideal candidate and it would be great if these
two lines worked identically:

    qemu -b c

    qemu --boot c

There isn't getopt_long_only function in MinGW library. So double hyphen
"--" is needed for long option which is more than two characters.

I have written mini how to on Windows. Please see my site.

I just updated the web site to include more information about the 
Windows port.

You can precise that you are talking about W$ version.

It is fixed in the CVS.

I will give it a try.
Thanks for your time and this beautiful piece of software.

[Qemu-devel] WinXP status

[Grzegorz Kulewski]

Hi,

I can install WinXP without any problems. It is normal WinXP without any 
service packs under academic licence. It automagically selected higher 
resolution without any external drivers (although it does not recognize 
the type of graphic card).

But I formated my partition (one drive, one partition about 2.5GB, dd 
image) to ntfs (quick format). So I cannot copy network and graphic 
drivers to it from linux. So I created second 50MB image, attached to hdb 
and formated under windows to fat. Then I mounted it under linux and 
copied three small files on it. I "booted" into WinXP back and the 
second drive was gone. I checked in device manager and there was some 
error that this device is already present in system. So I deleted it and 
rebooted. I made few more tests and the second image can be seen in My 
Computer only if it is attached to hdd. But even if it is, WinXP can 
detect that it is nearly free fat partition but can not see any files
or directories on it.

Did I do something wrong? Or is the qemu disk emulation broken? And what 
with qemu dma support for disks (disk seem to work in pio mode)?


Thanks in advance,

Grzegorz Kulewski
