This is a comparison of the various emulators that you can use to test your operating system without having to reboot your computer or risk your hardware.

Overall, VirtualBox offers the richest set of features, along with very fast performance. Bochs is by far the slowest, but that is because of its full emulation, which gives it the highest accuracy. None of them are necessarily 'better' than the others. This comparison is just to point out their differences.

None of them are necessarily 'better' than the others. This comparison is just to point out their differences. It can't hurt to use more than one emulator (or several), in order to test your OS on a variety of platforms without using real hardware.

Supported Disk Image Formats

This chart shows the file formats for an emulated hard disk. The emulators usually support only a flat image for a floppy and an ISO image file for CD-ROMs.

Flat Concatenated Sparse/Stackable Journaling Growing VMWare format
Bochs Yes Yes Yes Yes Yes Yes
QEMU Yes No Yes No No Yes
VirtualBox Yes No No No Yes Yes
Microsoft Virtual PC Yes No Yes No Yes No
  • A flat image offers no special features and takes up the full amount of disk space that it emulates.
  • The concatenated format allows several separate files to emulate one combined hard disk; useful for partitions.
  • A sparse image does not store blank space, so you could emulate a 1 GB hard disk, but it would only take up 200 MB of space if it had 800 MB free space.
  • Stackable images allow a 'base' read-only image. Any changes are stored in a new image that is layered on top. Useful if you want to remove any changes to a 'good' disk.
  • Journaling images keep track of changes made by each session, and they can be undone/redone in order.
  • Growing images are similar to sparse images. They start small when the emulated disk is empty and expand as more data is written.
  • Apparently, the VMWare format for disks is popular because several emulators support it.
