The only info I have is d= oing "bhyvectl --vm=3D --get-exit-reason" and that's basic= ally it, which it isn't the most helpful. You can also do "--get-all" in th= e previous command to get all of the stats for that vm (even if it already = crashed, as long as it's still in /dev/vmm/". Someone did = mention before I could try and use dtrace and see what happens but yea. It = would be nice to have more documentation on how to debug bhyve for a variet= y of different cases. Jonathan
