A virtual always gets its network traffic from the host's network stack. If your firewall is a virtual, the firewall's physical host is not behind it.

Another crack on vms: recently I saw a discussion claiming that virtualbox and some (non-enterprise?) versions of vmware don't pay real attention to fsync. I didn't fully understand the discussion but it sounded as if any OS on top of either effectively had file systems that were option async whatever their real mount options were. I don't have much use for virtual machines normally, but reading this made me all the more skeptical.
