Environment: dom0 is OpenSolaris 2009.06, with Open HA 2009.06 installed. Because of Open HA, physical network connectivity from the dom0 to the switches is via a pair of NICs, e1000g drivers. Multiple VLANs configured on the dom0, this domU should exist on only one of them.
Problem: HVM domU 64bit Debian 5.0.3 can see inbound traffic from the world but can't respond. Details: If I ping from the dom0 or any other machine on the same subnet, the ARP requests are making it to the domU (As shown by 'cat /proc/net/arp' getting populated with ARP entries that correspond correctly to the ping initiator's IP address and MAC address on the domU) In domU, 'ifconfig -a' shows the TX and RX packets increasing as expected. Unfortunately, since the domU can't get to the network, I can't get to the repositories to install tcpdump... >From the dom0, if I do 'snoop -d ' against the xvm vnic that Xen creates, I >see the broadcast packets for the ARP request, but no response. 'dmesg' on the domU shows the network device as a 'RTL-8193C+' during discovery.
