[Qemu-devel] Can't link kqemu kernel module on AMD64 system?

[Qemu-devel] Can't link kqemu kernel module on AMD64 system?

[Jeff Wiegley]

I have an AMD64 system with Debian pure64 distribution.
My kernel is 2.6.12-rc6 (I'm stuck with it due to a particular
patch fix)

Is it possible to get kqemu working on this system?

When I compile I get this:

make -C kqemu
make[1]: Entering directory `/home/jeffw/Downloads/qemu-0.7.0/kqemu'
make -C /lib/modules/2.6.12-rc6-jw9/build M=`pwd` modules
make[2]: Entering directory `/usr/src/linux-2.6.12-rc6'
   CC [M]  /home/jeffw/Downloads/qemu-0.7.0/kqemu/kmod.o

supported

make[1]: *** [kqemu.ko] Error 2
make[1]: Leaving directory `/home/jeffw/Downloads/qemu-0.7.0/kqemu'
make: *** [all] Error 2

I saw the posting about a x86-64 alpha version of kqemu coming out in
"the next few days" but that was a month ago. Did this happen? Or does
it just not work on AMD64 systems/kernels yet?

Thanks,

It didn't happen.

kqemu is still 32-bit only.

Short answer is no. The patch does not work for 64-bit kernel/system.
