When I turn on a virtual host with 2GB ram Ubuntu 12.10 64 bit, I found that it will affect the host system.
The response of pressing keyboard is slower. Sometimes it will cause repeating keypress even i just press the keyboard once.
The effect is just like: teeeeeeeeeeeeest
When I close the VirtualBox, the problem goes away.
Host: Windows 7 64 bit, Virtualbox 4.2.6
Any clues? Thanks!
