I have the details on the setup posted to virtualbox's forums, here: https://forums.virtualbox.org/viewtopic.php?f=6&t=60975
Essentially, I'm running ZFS on FreeBSD10 in VBox running in Windows 7. Rather than the other way around. I think I mentioned that earlier I just created a short post about the NAT Network issue, here: https://forums.virtualbox.org/viewtopic.php?f=6&t=60992 On Tue, Apr 1, 2014 at 11:58 AM, Jason Belec <jasonbe...@belecmartin.com>wrote: > I run over 30 instances of Virtualbox with various OSs without issue all > running ontop of ZFS environments.
