[Qemu-devel] RE: Qemu-devel Digest, Vol 25, Issue 38

[William barath]

I've tried recently to build both qvm86 and kqemu kernel modules with 
identical results...

Instead of building the module, it builds ALL other kernel modules.  Luckily 
this only takes a few minutes on the second and third attempt!

I'm using SuSE 9.1 FTP edition with the stock kernel "2.6.4-52-default", and 
today's CVS of both qemu and qvm86, as well as the kqemu plugin tarball from 
Fabrice's site.

I noticed someone else using an older 2.6 kernel saying they had 
difficulties building the module and someone else on the list braying back 
the instructions from the README file, "what's so difficult about..."  the 
difficulty seems to be that the P=`pwd` option seems to get ignored by the 
module build system.

I've tried moving the qvm86 module into the kernel sources and moving the 
makefile into the qvm86 directory anong with a few other tweaks and haven't 
been able to figure out exactly what I'm doing wrong to overcome the 
problem.  It would help if I knew what to do /right/ to build it manually.  
;-)

Do I have to install a new kernel to get around this?

Probably. 2.6.4 is fairly old. I'm not particularly interested in making qvm86 
support such old kernels.

don't know anything about the qvm86 module, but the kqemu
module is supposed to be dropped into the qemu source
directory as a subdirectory called kqemu.  You rerun
configure with the kqemu parameter and it should build.
the only thing you have to do with the install after it
is to do a modprobe kqemu. You an see if it worked if
there's something in /var/adm/messages about the kqemu
module being activated.

Sounds like you put the kqemu module in the wrong
directory.

I was using Sun's Java Desktop system, with a kernel
rev near what you have and it just worked (well, once
I modprobe'd the module)

I don't think you need to install a new kernel.  Just
put the kqemu module in your source directory for
qemu and reconfigure-make-install
