Yeah sure:

VBoxManage createvm --name Stage11 --ostype Ubuntu_64 --register
VBoxManage modifyvm Stage11 --memory 1024 --boot1 dvd --nic1 bridged
--bridgeadapter1 em0
VBoxManage storagectl Stage11 --name "SATA Controller" --add sata
--controller IntelAHCI --hostiocache on
VBoxManage storageattach Stage11 --storagectl "SATA Controller" --port
0 --device 0 --type hdd --medium "st11.vdi"
VBoxManage storagectl Stage11 --name "IDE Controller" --add ide
--controller PIIX4
VBoxManage storageattach Stage11 --storagectl "IDE Controller" --port
0 --device 0 --type dvddrive --medium ~/ubuntu-12.10-server-amd64.iso
