I have a laptop running 8.2-prerelease GENERIC.  I have virtualbox ose
3.2.12 from ports (and kmod as well).

I've only installed windows guests in vbox.  I've installed windows 2008
server 64, windows vista 64bit, and windows 7 32bit.  I have the vbox
hdd images on an NTFS filesystem mounted using fuse.

My box is a dual boot machine between FreeBSD and Windows.  My desire is
to be able to utilize the same virtual machine in vbox on both my
Windows and FreeBSD installations.

I can successfully utilize the virtuals in vbox (same version) in
Windows.  However when I utilize any of the virtual machines in FreeBSD,
they run for several minutes and eventually "freeze".  Freeze may not
necessarily be the correct term.  All windows processes on the virtual
machine begin to die.  First one process, then another, then all.  Hard
to explain, which may not help my cause here.  But, most important
fact... in Windows they work fine... under FreeBSD they run for a while
and then cease to run.  When the VM is good and dead, it is always dead
with the little vbox virtual hard disk LED lit up (no idea if that is

Previously, they would run for a *very* short time.  seconds? minutes?
and then die (sometimes I couldn't login).  I disabled sound support and
now they run for 10-15 minutes.  Had one run for an hour or two the
other day, but can't reproduce that.  Usually 10-15 minutes max.

Network works fine inside the virtual.

I'm new to VirtualBox on FreeBSD.  I've used it a bit on Windows with
good results.

I did try a windows guest on a non fuse filesystem just to rule that
out, but had same issue.

What else could I provide that might allow someone to point me in the
right direction here?
