Oracle VirtualBox Tips

• Add more physical memory

• Install Guest Additions

• Enable memory overcommitment (Page Fusion & Memory Ballooning)*

• Disable Host I/O cache

• Use dynamic disks to save on space

• Use snapshots

Snapshots

• Take a point in time snap of your VM

• Convenient method of testing changes

• Roll back and forward using snapshots

• Use sparingly (2-3) at the most

• Read-only. New data written to snapshot deltas

• Can require a lot of space
