It seems that over the last few months, SunOracle have finally fixed some of the most annoying bugs in VirtualBox:
- Stale DNS info: fixed in 3.2.2, which was released a few days ago.
- Keyboard: fixed, but I don’t know when. I just suddenly realized I hadn’t encountered that bug in a long time. Possibly related to this bug, which was fixed in 3.1.8.
- Clock: fixed; not sure when, but probably in 3.1.4. There is a changelog entry that sounds about right, but no ticket.
