It's easy, just read qemu-doc.html.

But if you need just quick answer:

qemu-system-i386 -cdrom /path/to/iso -hda /path/to/file.img -net user -daemonize

More advanced example (which I always use):

kvm -name vm -nodefaults -monitor vc -cpu host,-svm -m 1024 -drive file=file.img,media=disk,cache=unsafe -drive file=/path/to/iso,media=cdrom,readonly -net nic,model=rtl8139,macaddr=02:04:06:88:fa:bc -net vde,sock=/tmp/kvmnet.vde -vga vmware -daemonize

instructs KVM to provide host CPU definition into VM, add 1G memory, put a disk first then cdrom second, add RTL8139 NIC with specified mac address and attach it to VDE switch, then add vmware virtual GPU to have more video modes available and daemonize it.

  • I glad I helped you! Do you want to run amd64 ISO or do you concern future issues when running qemu on amd64?

  • Then you need your host to be also amd64, or kvm acceleration (if you use any) will not work. However qemu-system-x86_64 must be always available and run amd64 ISO perfectly, so try it out first.
