I don't know anything about the vtnet driver for virtual hosts,
nor whether or not what you're running should automatically assign
the vtnet0 device an IP address.

Is there a dhcpd (dhcp server) running on the host system?  That's
where the client will get its IP address from.  See man 8 dhcpd
and man 5 dhcpd.conf

There's no route (and ping doesn't work) because there is no address
assigned to the vtnet0 interface on the guest system.

netstat -rn
should show your existing routes
