qemu can't find x86 definitions

roelof · Guru Joined: 05 Feb 2009 Posts: 488

Hello,

In my make.conf I put this :

QEMU_SOFTMMU_TARGETS="i386 x86_64"
QEMU_USER_TARGETS="i386 x86_64"

Then I compiled qemu without problems.
But when I want to start qemu with qemu -cpu x86_64 -boot d -m 256 gentoo.img
I get this message :

Unable to find x86 CPU definition

What went wrong here ?

Try `qemu-x86_64` rather than just `qemu`.

Is this on a 32- or 64-bit host?

What do `equery f qemu | grep ^/usr/bin/` and `qemu -cpu ?` return?

Hello

Equery not found.

qemu: option '-cpu' requires an argument

It's on a 64 bit host.

You'll need to emerge gentoolkit for equery, alternatively ` grep /usr/bin/ /var/db/pkg/app-emulation/qemu-*/CONTENTS | cut -d ' ' -f 2` will give the same list.

Did you include the question mark (?) in the `qemu -cpu ?` command?

And what version of qemu is this?
In fact, could you post the `emerge -pv qemu` output?

Hello,

The equery gives no output.

qemu -cpu ? gives this :

Ah, I have 0.11 installed, may explain why I have differnt options.

See if `qemu-system-x86_64 -cpu ?` lists any 64-bit capable options, and try those if it does.

If not, you may want to upgrade to 0.11.

Also, 64-bit guest support seems to be somewhat experimental, at least with kqemu.

Oke,

I installed version 0.11.
When I do : qemu-system-x86_64 -boot d -m 256 gentoo.img

I get this message :
[code]
Booting from cdrom
Cdrom boot failure code : 003
Boot failed : could not read the boot disk.
[code]

Im sure the dvd is bootable because I have installed Gentoo with it.

How to solve this ?

Ah, tengo 0.11 instalado, puede explicar por qué he opciones differnt.
A ver si `qemu-system-x86_64-CPU?` Listas de 64-bit de opciones capaces, y juzgar a los si lo hace.
Si no, puede que desee actualizar a 0.11.
Además, soporte de 64-bit de resultados parece ser un tanto experimental, por lo menos con kqemu.
