Sets the format for a given drive.
Usually this passed directly to qemu ‘if’ sub-option of ‘-drive’ command line option. But in some special cases, such as when drive_format is set to ‘ahci’ or ‘usb2’, some special magic happens (see client/virt/kvm_vm.py for more information).
Currently available options in qemu include: ide, scsi, sd, mtd, floppy, pflash, virtio.
Currently used options in Avocado-VT are: ide, scsi, virtio, ahci, usb2.
drive_format = ide
