When i press start the ""bios"" screen from the vm comes up and then the host pc completely freezes. Even my mouse doens`t respond. Only a full reset of the host pc i can get the computer to turn normal again. 2.1.2 and 2.1.4 are having the same problem. Virtualbox 2.0.6 is working for me (so i downgrade every time) and is the only version which is stable for me. '''No vbox log is created and also no windows logs can be found.''' The freeze occur if i am using the host network interface but also on NAT and all the other network options. My host even freeze if i do the following: 2.0.6 on host. > Win xp guest > i install virtualbox 2.1.4 in guest > launch a newly created vm in the guest (so no os installed yet) > host pc freezes.
