I have discovered a problem with the VirtualBox virtio-net network driver that leads to a lockup of the host machine's kernel and the need for a hard reset to make it working again. The bug had been reported to the VirtualBox bug tracker 8 days ago (https://www.virtualbox.org/ticket/11863), with the usual reaction from Oracle support (i.e. none).
FWIW: *not* confirmed for : 64-bit Linux host = Debian Squeeze 6.0.7 amd64 32-bit Linux guest = Debian Squeeze 6.0.7 i386 VirtualBox = 4.1.26 (guest network adapter set to virtio for the test) '$ tracepath 8.8.8.8' run in the guest works fine, and no unpleasant effects are noticed on either host or guest. I note that VirtualBox 4.1.26 (latest update to 4.1 series) was released on the same day as 4.2.14 (latest update to 4.2 series) - specifically 21st.June.2013 - which happens to be the same day you reported the problem here after getting apparently zero response from Oracle Support for 8 days. Maybe they just silently fixed the bug during those 8 days - in which case they should have had the manners to let you know.
