I am in need of using the the same set of IP addresses to support a group of KVM guests running different Linux distros on the same machine: Scientific Linux 6.3, 64 bit. cobbler 2.2.3.
With cobbler, to enable such the support of duplicated IPs is simple: vi /etc/cobbler/settings and done. But to my disappointment, the $insert_cobbler_system_definitions in /etc/cobbler/dnsmasq.template writes out a line for each known Mac address. The result: upon a cobbler sync, dnsmasq issues the following and refuses to restart: dnsmasq: duplicate IP address 192.168.123.101 in dhcp-config directive. It's been known at least since 2009 that if one uses a syntax like the following: dhcp-host=<wlan MAC>,<lan MAC>,<IP address> then dnsmasq would handle the situation gracefully. How can I make cobbler to use such a syntax? Yes. I can use the same set of Mac addresses for these KVM guests and "get around" the issue for now. But we do have plan to migrate this single host KVM based POC setup to a set of physical test server for more capacity. So, using different Mac Addresses is just more realistic and forward looking.
