I spend some time on this test today and got it working. The bottom line
is, we add a static arp cache entry for:
(IP of vm + MAC of vm interface) + corresponding tap interface
^ Guest side info ^ Host side info
If you issue a ifconfig on host while tests are running, you'll see the
tap interface:
virtio_0_5900 Link encap:Ethernet HWaddr 8A:65:51:1F:6A:95
inet6 addr: fe80::8865:51ff:fe1f:6a95/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:65520 Metric:1
RX packets:560511 errors:0 dropped:0 overruns:0 frame:0
TX packets:565406 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:36697168035 (34.1 GiB) TX bytes:36697563087 (34.1 GiB)
Then, if you run:
arp -s 10.16.74.148 9a:0b:5d:7a:e6:eb -i virtio_0_5900
It will work. Of course, the actual values of the ip and MAC addresses
have to be checked on guest side.
I have rebased this test and re-sent. You might try it, but now I think
it's going to work for you, as it did for me.
Moving closer to the completion of this patchset,
Lucas
