VirtualBox restoration from Appliance file (*.OVF) reboots on and on

Virtualbox reboots on and on and on. To solve, do following:
If you are seeing this problem repeatedly you can manually disable these drivers (with no negative side effect) by going to the following location in the registry:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSet?ServicesProcessor
Or
HKEY_LOCAL_MACHINESYSTEMCurrentControlSet?ServicesIntelppm

And changing the ‘Start’ value to ‘4’.

Next is to disable the network card and then choose it in NAT mode. After a restart, visit network connections and enable the card there. This should now solve the problem for good.
