oops. yes. here's an example: /usr/local/bin/qemu-system-x86_64 -boot c -name "w7" -m 6G -smp 4 -M pc_q35 -cdrom /images/isos/en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso -hda /images/w7-q35.img -vnc :5 --enable-kvm -bios /root/seabios/seabios/out/bios.bin -acpitable file=/root/seabios/seabios/out/q35-acpi-dsdt.aml -monitor stdio > > > The error I run into is: > > > > "A required cd/dvd device driver is missing.
