that's with akaros port-fowarding host port 23 (which you don't see in
my .ssh/config) to the guest port 22. the guest got its IP, route, and
DNS server from DHCP (synthetic, inside the VMM). the DNS is actually
the host's DNS server.

ARP is also done synthetically. the VMM just responds to all ARP
requests with the host's fake ethernet address.
with a flip of a bool, i can give the guest the host's IP address too.
it all gets translated, so it doesn't matter what addresses i give it.
in that case, the host can just use static configs or still use DHCP.
ex:
tc@box:~$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 1C:B7:2C:EE:52:69
inet addr:10.107.10.100 Bcast:10.107.10.127 Mask:255.255.255.192
inet6 addr: fe80::1eb7:2cff:feee:5269/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:171 errors:0 dropped:0 overruns:0 frame:0
TX packets:115 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:18546 (18.1 KiB) TX bytes:14775 (14.4 KiB)
and reaching hosts that appear to be in the broadcast domain works fine:
tc@box:~$ nc 10.107.10.69 8080
hello from tc
hi from other box
i've got a bunch of other issues to sort out (including a race that may
have a lengthy solution and guest-to-host communiciation), but the
basics seem to work so far. oh, and there's a nasty bug with VMCS unload
that i kick every so often. good times! (as always)
if you're curious, check out my net branch. and let me know if you
happen to have any questions about protocol xsums. =P
