Hi to all, 

 thanks for the suggestion to make use of the -cpu nehalem switch.

I try to use the option you suggest but I receive this error: 

Unable to find x86 CPU definition
[marcian@metal x86_64-softmmu]$ ./qemu-system-x86_64 -cpu ?

x86           [n270]

x86          [kvm32]

x86         [qemu32]

x86       [core2duo]

x86         [phenom]

x86         [qemu64]


Unfortunately, after reading the docs, I still don't know how to enable nehalem.


Could anyone give me some hints on this issue?



thanks in advance

Marco

It should be -cpu Nehalem.

What version of qemu are you using? Have you ran "make install"?

We neither have "nehalem" nor "Nehalem" as CPU definition in qemu or
qemu-kvm.

In fact, I stumbled over this problem a while back as well [1]. I tried
all obvious CPU types in the hope Windows is only unhappy about some CPU
features, but found no working combination as well.

We do in both. Look at sysconfigs/target/target-x86_64.conf. But for
qemu to find this file it needs to be installed.

I have another problem: Windows 7 x86 setup hangs when "Setup Is
Starting Windows". Any suggestions?

Same. Try -cpu Nehalem. I am not sure this alone will help, but worth
trying.

[TeLeMan]

I tried. This issue should be associated with some IO device or bus.

Hmm, I see. Looks like an issue of its own. We read datadir files from
the build directory, but not those conf files.
