Solved FreeBSD 10 i386 data corruption problems in virtual machines (WAS: Do not use soft update ...)

Edited the title and marked this as solved since a solution is known and seems to work.

Corruption with disk I/O with unmapped I/O on i386/Virtualbox and potentially other virtualization systems has been a known issue. Remember release notes and errata are usually your friend when it comes to big issues like this.

Thanks for editing the title! It makes a world of difference.

I think the title should be changed yet again to include AMD64 as well as numerous posters, including myself, have experienced this problem on real hardware running AMD64. If I lose power and have to go into single-user mode and run fsck -y all of my small partitions:

/      10 go

There is/was a specific bug with i386 VMs. Soft updates is a separate issue.
