[SOLVED] Qemu on Slackware-current stays black

comfree · 09-27-2013, 09:03 AM

I recently ran into the problem that qemu on my slackware-current machine is not working properly.
When I try to start with:

Code:

qemu-kvm -cdrom opensuse.iso -m 4096 -smp 4

or with

Code:

qemu-system-x86_64 -cdrom opensuse.iso -enable-kvm -m 4096 -smp 4

Doesnt matter if I give it a less memory or less cpu power, its always the same.

The qemu window pops up but it stays black.
The intel-kvm and kvm modules are loaded.
This happens to me when using qemu:

1.2 from alienbobs repo
1.3 from slackys repo
1.4 from slackbuilds 14.0 repo
1.6 from slackbuilds current repo

With the versions 1.2, 1.3 and 1.4 I see the boot options from the iso, after selecting whatsoever it stays black.
My CPU is used a lot by qemu.

Does anybody know the problem here? I don't get it...
Even after building qemu without slackbuilds and my own options it won't work.
VirtualBox is working properly but I'd like to stay with qemu.

Thanks.

This is what I have been using for quite some time, still works for me:

Code:

export QEMU_AUDIO_DRV=sdl
export SDL_AUDIODRIVER=alsa
qemu-kvm --enable-kvm -localtime -m 2G -sdl -display sdl -vga vmware -usbdevice tablet -smp 2 -net nic,model=virtio -net user -drive file=VirtualDrives/slackware-14.0.img,cache=none,if=ide &

your cdrom looks right, maybe add the -display or --enable-kvm?

Your problem (or what I believe you describe as your problem) was previously discussed here:

Thanks a lot! I did not try the -sdl option. It's working now!

Solved.
