I have an Ubuntu(10.04.3 64bit server) guest VM on an ubuntu(11.04 64bit desktop) host.
The guest VM defaulted to the first network adapter as NAT.
Now I want to enable bridged mode, but every other configuration besides NAT freezes the VM in startup.
Ive tried giving virtualbox SU-privileges but the problem persisted.
any tips or tricks?
Screenshot:
After a few minutes, the manager starts displaying the following:

From here on nothing happens, the VM itself is frozen and cannot be closed, the vm managed can be closed but 2 processes stay open which prevent it from being opened again, I assume the problem lies within these processes:
VBoxSVC & VBoxXPCOMIPCD
