I’ve been trying Virtual Box (currently 4.0.6) out for the past few weeks on Windows 7 x64. I’ve got to say it’s scary to use. Especially after I got some emails from the daily/weekly anacron runs last night which simply state “Segmentation fault” from a test VM that I setup and left running. Ouch! I’ve also observed other random virtual disk corruption…
The only problem here is that the killer feature that no one else “supports” is the raw disk access. I want to use this for my primary file server. Can I trust Virtual Box? Maybe… the file server is running Nexenta with ZFS over two 1TB disks in a Raid 1 configuration… or I could leave it on real hardware where it has a real chance of working without any problems
