Um - if you use bridged mode, your virtual interface can and should have
a different address than the host's interface. Certainly this has always
been the case with my VB guests. For example, if using DHCP, they get
their own IP address from the server. If using IPv6, they autoconfigure
their own link-local address and their own global unicast address.

Here is the ethernet interface on an XP virtual I just started (some
line wrap might happen, sorry):

Connection-specific DNS Suffix  . : biplane.com.au
IP Address. . . . . . . . . . . . : 192.168.1.202
Subnet Mask . . . . . . . . . . . : 255.255.255.0
IP Address. . . . . . . . . . . . : 2406:a000:0:100:2040:4677:2502:cc10
IP Address. . . . . . . . . . . . : 2406:a000:0:100:a00:27ff:fe43:6ddc
IP Address. . . . . . . . . . . . : fe80::a00:27ff:fe43:6ddc%6
Default Gateway . . . . . . . . . : 192.168.1.1
                                    fe80::209:6bff:fe30:3e92%6

And here is the network interface on the Ubuntu 9.04 host:

wlan0     Link encap:Ethernet  HWaddr 00:22:fb:54:9b:80
          inet addr:192.168.1.201  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: 2406:a000:0:100:222:fbff:fe54:9b80/64 Scope:Global
          inet6 addr: fe80::222:fbff:fe54:9b80/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:208552 errors:0 dropped:0 overruns:0 frame:0
          TX packets:181322 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:240351147 (240.3 MB)  TX bytes:82259449 (82.2 MB)

Note the different IPv4 and IPv6 addresses. The MAC addresses differ
too.
