My host is - ubuntu 12.10 x64 Desktop with latest virtualbox installed. Guest OS is Ubuntu 12.10 x64 server edition.
I execute this virtual machine as root user on Ubuntu host machine to connect ports like 80 and 22 from host machine to guest.
The problem is, host hardware hard resets (reboots) while I work with guest OS on virtualbox.
