Here are the technical (not in tremendous detail I admit) notes from bugzilla 506898: "When installing to a z/VM guest or LPAR that is configured with 1 CPU and/or less than 2 GB storage (memory), the installer will prompt for the network configuration, regardless of whether these parameters appear in the PARM or CONF files. This is due to an unexpected side effect of a kernel change in RHEL 5.4, and will be fixed in the RHEL 5.5 installer. There are multiple ways to workaround this issue: First, define at least 2 CPUs to the LPAR or z/VM guest. Note that if running under z/VM, defining an additional CPU does not require an additional physical IFL. If an additional CPU cannot be defined, the second workaround is to define at least 2 GB storage (memory) to this guest or LPAR. Note that under z/VM, this does not require additional physical storage. If neither of these workarounds are possible, please contact Red Hat support to obtain an intermediate kernel fix before RHEL 5.5 is released." Here is a little more technical detail: "The s390 parameter line has been marked as __initdata. During parameter parsing, pointers to parameters are stored in an environment/argument vector. Before the init process is started, all __init* memory locations are freed and, thus, the saved parameters are no longer available. Solution: Remove the __initdata annotation from the s390 kernel parameter line." Justin On 01/28/2010 10:39 AM, Scott Rohling wrote:
I don't have a RH login or anything, so can't view this... but very curious bug! I was really confused when Sterling suggested defining a 2nd CPU.
