9163	VirtualBox 4.0.10 doesn't detect my network card anymore	mediaf		"Since I upgraded to the last Vbox release, I can't start any guest ( I have a debian 5.08 and a Windows Seven )
I get an error message : Failed to open a session for the virtual machine
Nonexistent host networking interface
Unknown error creating VM

I have VBox Installed on a notebook with Windows XP Sp3.
I have an ethernet card ( Intel(R) 82577LC Gigabit Network Connection ) a wireless card (Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC ) and the virtual VirtualBox Host-Only Ethernet Adapter.
When using the host Windows XP, I don't have any problem with the two network cards, but Vbox seems to not detect my ethernet card : in the dropdown menu used to choose the network card when configuring a guest, only my wireless card appears, so if the Wifi isn't activated the guests with bridged mode network refuse to start throwing ""Nonexistent host networking interface"" "	defect	closed	network	VirtualBox 4.0.10	duplicate			Linux	Windows
