When running 64-bit guests in 32-bit Ubuntu 12.04, the host with high probably goes into abrupt reboot sooner or later. There's upstream bug for this:

https://www.virtualbox.org/ticket/10528

It reports that the issue was fixed in Virtualbox 4.1.18 . Please consider upgrade for the package in 12.04. Please also consider this as high priority, because abrupt reboots diminishes user experience largely. Thanks.
