How to use KQemu?

Gullible Jones · 2005-07-26 21:27:46

Uhh... What's all the stuff about disk images in the help file? Is it possible to just *use* this program like Dosemu or DOSbox, or do I have to do all sorts of bizarre stuff to do anything with it?

deficite · 2005-07-26 23:22:23

There's a page in the wiki for it. You need to make a disk image to use qemu, but I usually set up a loopback device and I can write and read to it just like it was a drive on my computer.

D'oh, forgot to look in the wiki. Thanks. :oops:

I have made the pacakge kqemu from AUR and when I:
[root@myhost qemu]# modprobe kqemu

I get

FATAL: Error inserting kqemu (/lib/modules/2.6.12-cko2-swsusp2/misc/kqemu.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Also the PKGBUILDS from Wiki do not makepkg. Why?

What could be the problem?

What is your output from the PKGBUILDs on the Wiki? I'm the last person to touch the PKGBUILD on there when I added the stuff for kqemu and it worked fine back then.

Judging from what happened to DTW's cedega-cvs PKGBUILD, the one in the wiki is probably messed up from the recent migration.

Check out here ... new version to follow

If I use the PKGBUILD and configure.patch from the WIKI it doesn't makepkg at all.
Here is what I get:

==> Starting build()...
/usr/bin/makepkg: line 560: build: command not found
==> ERROR: Build Failed. Aborting...

:?:

Okay, I can compile qemu just fine and I can load the kernel module from the kqemu package on the AUR just fine. What does your dmesg say when you try to insert the module?

I changed to wiki to point to the AUR. Two PKGBUILDs floating around for the exact same thing is not very good.

giorgosc61 · 2005-07-30 03:53:24

Here what I get from dmesg when I compile the modified PKGBUILD FROM aur:

kqemu: disagrees about version of symbol struct_module

Send it to the maintainer of the AUR package.

giorgosc61 · 2005-08-22 18:28:04

Hello.

If i compile qemu with setting in makepkg.conf
-athonxp -O3

will I get any speed increase?

Gullible Jones · 2005-08-23 07:56:57

1. Has to be -march=athlonxp, unless you want to use -mtune.

2. I used -O3 a couple times when on Gentoo... If there was a speed increase, it was imperceptible. On the other hand, compiling took much, much longer...

I've been trying to use serial port in qemu.
I want to redirect /dev/tts/USB0 so an applications using com1 in qemu can read it.
I tried qemu -serial stdio /dev/tts/USB0 with no luck.
The same with -serial tty and -serial vc.
How can I do that?
