BridgedInterface needs trailing blank

[Phantom2398]

My network interface card is a "NVIDIA nForce 10/100/1000 Mbps Ethernet", host is Windows 10 20H2 build 19042.844. When selecting the NIC as bridged interface in the network settings, it is stored to the .vbox file as "NVIDIA nForce 10/100/1000 Mbps Ethernet", however when starting the related guest I get an error message that the virtual machine cannot be started as the network interface is not existing. I can resolve this by adding a trailing blank to the BridgedInterface in the .vbox file as: <BridgedInterface name="NVIDIA nForce 10/100/1000 Mbps Ethernet "/> before starting VirtualBox. But whenever I change some settings of the guest, the trailing blank is removed, so I must do this again and again.

Please, can you run VBoxBugReport with the name of the VM in question as the argument and provide the archive with the collected information that it creates.

It's strange that the trailing space you add manually is removed on unrelated changes, that shouldn't happen. Instead of adding the space directly to the vbox file you can try:

VBoxManage modifyvm "VM name" --nic1 bridged --bridgeadapter1 "interface name "

I have the same NIC as Phantom2398, host is Windows 7. If I start any VM (WinXP, Lubuntu), there is an error: "Could not start the machine WinXP because the following physical network interfaces were not found: NVIDIA nForce 10/100/1000 Mbps Ethernet (adapter 1)", even though it is selected in the VM network settings. 6.1.0 and later all have this issue (tested).
