After weeks of operation, suddenly last night a couple of the VMs stopped functioning properly. When logging into the VMs using SSH and doing something that involved disk access (such as ls), all you get back in the console is ""Bus Error"". There are some ATA problems reported in the VBox.log, so I'm guessing it has something to do with the storage subsystem. I hope someone can make sense of the log." defect closed virtual disk VirtualBox 3.0.4 fixed Linux Linux
