The guest storage control is SATA AHCI with host I/O caching enabled. Host info: OS Type: Linux (2.6.18-194.el5) VirtualBox: 4.1.4 (74291) Processors: Intel(R) Xeon(R) CPU 3060 @ 2.40GHz (2) HWVirtEx, PAE, i/o error Long Mode (64-bit) It seems during times of high I/O, like backups and etc, the guest filesystem resets to read-only. We have this issue with both ext3 and ext4 filesystems. Switching to ext3 seemed to lessen the occurrences though. Here is a snip of syslog around the time of the corruption..
