VirtualBox cannot start on F17

[Paul Smith]

Dear All,

I have just installed F17 (clean installation), and when I start my
virtual machine through VirtualBox, I get the following error:

Failed to open a session for the virtual machine WindowsXP.
Failed to open/create the internal network
'HostInterfaceNetworking-eth0' (VERR_INTNET_FLT_IF_NOT_FOUND).

Additional information:

# rpm -q VirtualBox-4.1
VirtualBox-4.1-4.1.16_78094_fedora17-1.x86_64
#

Any ideas?

Thanks in advance,

Paul
