This happened with FreeBSD guest with UFS (journaled soft-updates) and
FreeBSD host.
What is out of normal, it rolled back for many hours (~20).
I hit this unexpected problem: my host had an ungraceful shutdown while
FreeBSD 9.1 STABLE was running in the VirtualBox VM. After reboot of the host
and VM, local ufs file system was missing all recent updates for at least 20
hours (!!!)
My question is, how is this possible? Is this related to
Virtualbox is very aggressive about caching writes. This is how it
achieves its perceived speed. I wouldn't expect to see this happen on
real hardware. I might have to try this out though and see if I can
reproduce it reliably.
