Last I checked running with softdeps in virtualized env, I got some panices. It was few years (2 max) ago, but IIRC softdeps are not that heavily developed in time like other parts of the kernel. From what I remember from the analysis back than, slower the drive is, higher chance you get panic. So I would definitely be careful in using softdeps in exactly this situation where you do have high-latency drive beneath the softdep mounted drive image. I had exactly the same high-latency, VBox drive on fragmented ZFS on Solaris 11. Killer option for softdeps. So try, but keep praying if you do that in production...
