Guest OS Version

I I think that event is not related to the GuestOS.

It seems to me that you are trying to bridge to a host NIC named "eth2", however that is the NIC device naming convention used on Linux hosts.

However, you have posted in "Windows Hosts", plus your command line clearly shows the command prompt of a Windows Host.

So we appear to have a contradiction here. If you stated the problem accurately then the error message seems correct to me.

Thank you for your reply.
It had given a false recognition.
eth2 it is decided, for example.
Work with other names are the same.
This problem has occurred in the Windows 7.

Dialog is displayed after you run this command.
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" startvm hostname
Will you not be able to perform the same operation on the command and click on the "Change Network Settings" button ?
