The launch command was: /qemu-system-x86_64 -enable-kvm -vga cirrus -cpu host -smp 4,cores=4,threads=1 -m 4096 \ -netdev user,id=user.0 -device e1000,netdev=user.0 \ -usb -usbdevice tablet \ -drive if=pflash,format=raw,readonly,file=/usr/share/edk2.git/ovmf- x64/OVMF_CODE-with-csm.fd \ -drive if=pflash,format=raw,file=/usr/share/edk2.git/ovmf- x64/Windows_ovmf_vars_x64.fd \ -drive file=/dev/koalita/koalitavm,format=raw,cache=none,aio=native,if=virtio I tried to launch it using the virtio disk, the ide disk, and empty disk with the windows 7 installer, and even without disk to see if the cdrom launchs ok.
