Now that I am busy setting up UDA 2.0 (beta14) for a customer to be able to reinstall their 50+ VMware servers, I stumbled upon this message. The install would hang briefly, then proceed to a “press any key to reboot” prompt. Not too promising…

After searching the internet I found a lot of blog entries on exactly this error. I could not find any useful hints or tips that would solve my problem; I have been checking the disk layout over and over again, to make sure no mistakes were made there. I was starting to pull my hair out, because it did work previously.

Then I started thinking; the customer in question has multiple PxE servers in the same network, and special DHCP entries were created for all vmnic0 MAC addresses, so that option 66 and 67 could be set to point to the UDA appliance. I think their DHCP server denies DHCP to any MAC address unknown to it, because right before the “press any key to reboot” I saw something passing in the line of “unable to obtain a dynamic address”. I figured in the initial setup, the kickstart part tries to get a DHCP address using the Service Console virtual NIC (with a different MAC address each time you reinstall). So I tried to alter the “Kernel option command-line” from this:

ks=http://[UDA_IPADDR]/kickstart/[TEMPLATE]/[SUBTEMPLATE].cfg initrd=initrd.[OS].[FLAVOR] mem=512M
