Public bug reported:
When a CC is configured in SYSTEM mode, VMs are attached to a ethernet
bridge and depend on an external DHCP server (not controlled by
eucalyptus) to get an IP address. On a switched network, the NC and CC
cannot automatically discover the IP of a VM unless the VM uses the
network and the NC/CC arp tables are populated (allowing the NC or CC to
resolve the known MAC address with the allocated IP).
Possible solution - add an iptable rule to the NC that logs DHCP traffic
to syslog, periodically inspect syslog to discover IP addresses, send
single ICMP packet to discovered IPs to populate NC arp table, parse arp
table to discover MAC/IP mapping for VMs
