Andrea,
Thanks for your answers. I already patched the kernel and kvm (including rombios). The host boots up and the memory mapping is as explained in the patch. Now I am trying to launch a vm using memory mapping but it hangs after opening the sdl windows and before showing the bios messages. I am running qemu command from a console in the host that is running X and the command line is the following:
Qemu-system-x86_64 -hda ./dm.img -cdrom /dev/sr0 -m 32 -reserved-ram -boot d
- Is this command line correct?
- Should I run the vm without having started the X in the host machine?
- What should I see after starting the vm? Should the vm take ownership of the video card?
Thanks,
Pablo
