As I managed to get it working, will give a piece of advice, just save your current configuration by going to Diagnostics>Restore/Backup and get an iso from the latest release and re-install it, it takes 5 minutes max, and you can after just restore your backup to have everything in place. Just pay attention to create the VM with two cpus, legacy network adapters, enough memory (1gb), is better than try to adjust your current install. Oh, don;t forget that on Hyper-V and on 2.0, every time you boot the machine (after updates), or manually, you have to restart the interfaces, by going on the Hyper-V manager, opening the VM and selecting the Shell and then enter this:
ifconfig <name of your interface0> down
ifconfig <name of your interface0> up
ifconfig <name of your interface1> down
ifconfig <name of your interface1> up
in my case interfaces are de0, de1.
