Hi, all -- I'm doing some work to get koan provisioning virtual machines in my environment at the moment, and am running into some trouble. Specifically, I can't figure out how to actually give the virtual machine an IP address.
I do not allow DHCP except to registered clients -- that is, the DHCP config has a 1:1 mapping of MAC addresses to IP addresses, and there are no "anonymous" addresses available. For machines provisioned with cobbler directly, this is no problem, since the dhcpd.conf file is regenerated (including these mappings) each time I sync. However, for virtual machines, the MAC address is not known until I run koan on the host system, and it appears that the MAC address is not updated in cobbler. As a result, the virtual machine boots but fails to get an IP address assigned to it, and thus cannot get its kickstart file or build. Is there a way to either: - Tell koan to "push" a static IP address config based on cobbler's metadata about the virtual machine; or - tell cobbler to take the MAC address that is assigned to the virtual machine and sync, in order to create a dhcpd.conf file with the correct mapping of MAC to IP address? I've googled around, and it appears that most people get around this by having an open DHCP range. Are there other approaches that people have taken to this that I'm just not seeing? Any thoughts/pointers are appreciated. - Ian
