Hi Thomas. Good question--it is important not to submit bogus
fingerprints. But submitting targets running as a VMWare guest is
generally OK. Qemu is probably OK too. In both cases, please not the
situation in the comment box and be clear that the virtualized system
is the target. If the source machine (the OS you are running Nmap on)
is a VMware guest or similar, that is worth noting too.
Cheers,
