Hi,

i have some trouble with qemu-system-x86_64. Neither SuSE92-64 nor Ubuntu 
5.10-64 will install.

Here my env:
Host OS: SuSE10 (i586)
Kernel: 2.6.13-15.8-smp
qemu: snapshot20060315 (without kqemu )

./configure --prefix=/usr --cc=/opt/gcc33/bin/gcc-3.3 
--interp-prefix=/usr/share/qemu/qemu-%M --target-list="i386-softmmu 
x86_64-softmmu"
make CC="/opt/gcc33/bin/gcc-3.3" CFLAGS="-Wall -O2 -g -ggdb -g3 -ggdb3 
-fno-strict-aliasing -fomit-frame-pointer"


qemu-img create /localhome/qemu/86_64-test.img 4G

Thanks for any help.

[Qemu-devel] X86_64 problem

[Dave Dixon]

Greetings,

I'm building an initrd for netbooting headless/diskless cluster members. The
target platform is 64-bit ubuntu, and the development platform is 64-bit
ubuntu (albeit a very different computer physically). When I try qemu with
-kernel and -initrd, it says "This kernel requires an x86-64 CPU, but only
detected an i686 CPU." But it's definitely a 64-bit cpu - running a 64-bit OS.
If I show qeme -cpu ?, I get a list of only 32-bit cpus. What am I doing wrong?

Thanks,

-dave

QEMU is probably compiled for i386, not x86_64.

You need to run qemu-system-x86_64 to emulate an x86-64 CPU system.  
This has nothing to do with your host system.
