To clarify, the guest receives the NAT address of the VB Host as it's
DNS server.  It DOES NOT receive the Host's DNS server as it's own DNS
server.

That is, VB is _proxying_ the DNS requests, it is not simply giving the
guest it's own resolver.

No it does not.  As I said, VB _proxies_ (i.e. provides a DNS service to
the guest directly) the DNS request.

I will say it again.  No it does not.  Try it yourself.  Start a guest
in VB and look at what it receives in the DHCP reply.  It will have the
NAT IP address of VB as it's DNS server, not the address that the Host
is using for it's DNS server.  If your VB guest is Windows, do an
"ipconfig /all" and look at what the DNS server configuration says.

That is not an option.
