Hi, I launched a kvm guest from openstack, with only one NIC. (OpenStack Folsom on RHCE 6.3) The network setup is like this: virtual NIC -> vnet0 -> br100 -> eth0 -> physical network The vNIC has several IPs: 172.17.11.11/24 is the primary one, 172.17.11.65-66/24 are secondary ones. I expect that these IPs are visible to the host (and the LAN). But in the host, I can only ping the primary IP. Secondary IPs do not response. I then arping a secondary IP from the host (arping -I br100 172.17.11.65), and used tcpdump to monitor the packets in the guest. The guest clearly saw the arp request, and replied with the MAC of the vNIC (just like I arping the primary IP), but the host got no response. So is this not possible in kvm, or additional configuration is needed? Thank you!
