I use qcow2 because it's a bit more efficient, and a little faster. (Not that speed matters much here .. my 3-yr old desktop PC is still *way* more powerful than a 1990s '486 or Pentium PC.) I use guestfstools to "mount" the virtual disk from Linux. Works great. It's basically this: guestmount -a "$img" -m /dev/sda1 "$mnt" In other words: mkdir /tmp/freedos guestmount -a mystuff.qcow2 -m /dev/sda1 /tmp/freedos ..and that will "mount" the first (only) partition in my virtual disk, and make it accessible at /tmp/freedos. > Now, as I understand, the size of the file for qcow2, is way less than the > size specified... > because allocation is done only when needed... so I would suggest to oversize > the value... > maybe 3G? That's a lot. FreeDOS (like any DOS) is not big. What are you putting in that virtual disk? My "C:" virtual disk is 500MB, and that's much larger than I need to install OpenWatcom plus editors and tools. My "D:" virtual disk is like 200MB.
