[Qemu-devel] no virtual network emulation

[Savio Ramos]

Qemu 0.5.2-4 don't run. I did:

# apt-get install qemu

$ cd /home/savio

$ dd if=/dev/zero of=emu.img bs=1024 count=614400

$ qemu -boot a -hda /home/savio/emu.img

warning: could not open /dev/net/tun: no virtual network emulation
BIOS panic at rombios.c, line 1558


Any help?

It seems like you have to be root.

That's a warning.  It's harmless.  If you want virtual network, please go
ahead and set up tun support, then the warning will disappear.

No boot sector.  Did you expect a plain image to magically contain an OS?

your disk image if empty. So it's not bootable, and the BIOS can't find
a valid bootsector. So it stops...

I want to install win98 in emu.img. So, the image on hard disk is empty and I used the parameter "-boot a".

I did any mistake?

Could it not be turned into a more friendly error message like:

BIOS: Bootsector could not be found.

Or something similar?

Then you have to supply "-fda /dev/fd0" to qemu if you want to boot from
floppy (as you told qemu with "-boot a"), but since I don't think
Windows 98 comes on floppys (correct me if I'm wrong) you'll have to supply
"-boot d -cdrom /dev/cdrom" to qemu in order to boot from cdrom.

But don't forget to insert the floppys/cdrom.

you did not specify what "a" is supposed to be. you probably meant
$ qemu -boot a -hda emu.img -fda /dev/fd0
or
$ qemu -boot a -hda emu.img -fda floppy.img

you will also need "-cdrom cd.img" or "-cdrom /dev/hdc", since win98 just 
doesn't fit on a floppy.

hope this helps.

I don't know if it necessary or not virtual network to install win98 on Linux. Is it?

I want to install win98 on Linux. So, the emu.img don't contain an OS yet.

Any help?

Now I tried this:

# qemu -boot a -fda /dev/fd0 /home/savio/emu.img

The error message is below:

warning: could not open /dev/net/tun: no virtual network emulation
sb16: 0x3f is unknownAbortado

P.S. "Abortado" means "aborted" 

Any help?

Now I tried:

qemu -boot a -fda /dev/fd0 /home/savio/emu.img

When boot options appears it is possible to choose three options:
1. boot without cdrom support
2. boot with cdrom support
3. help

The options 2 and 3 works fine but the first crashes. The error messages is below. (note that this message appear in qemu window not in x-terminal of linux).

no drivers found, abort instalation
ERROR PCI READ CONFIGURATION FAILURE

My win98 cdrom can't boot. It's necessary boot with floppy, choose "boot with cdrom support", put cdrom in the device, change to "drive e:" and install windows of cdrom.

I inserted.

Any other idea?
