How to locate VirtualBox host?

[BorisUK]

I have a Windows 7 VirtualBox VM running somewhere on our network, but I do not know where

I can access the VM over the network and logon to it as admin.

Is it possible to establish which computer is hosting this VM? For example by looking at something in device manager or running a piece of software within the guest that would tell me the name of the host.

Thanks

Not with any network protocol provided by VirtualBox. The VM and the host are separate PCs, presumably both on the network.
