Description

We recently updated the docs with the latest values. They are the results of several tests Martin Kolman ran to figure out the minimum RAM for RHEL 7.4. See BZ#1410948#22. Is it possible that your unattended install contains additional commands (%pre/%pre-inst/%post scripts)? They can cause that the installer requires more RAM. See the paragraph right after the table: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-installation-planning-disk-space-memory-x86.html > Installing Red Hat Enterprise Linux using a Kickstart file has the > same minimum RAM requirements as a manual installation. However, if > you use a Kickstart file that runs commands which require additional > memory or write data to the RAM disk, additional RAM might be necessary. If you don't use any scripts in your unattended install, can you please provide me more details or the Kickstart file? Then I will talk with the developers to figure out if there are more situations that require more RAM and which should be mentioned in the docs. Actually the ppc64 section is correct, and documents that at least 1.664 MiB are required: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-installation-planning-disk-space-memory-ppc.html While the x86_64 section documents 1 GiB: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-installation-planning-disk-space-memory-x86.html Our mistake was to read the x86_64 section and assume it was for Power. Although Yash brought to my attention that the values given here: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-installation-planning-disk-space-memory-ppc.html Are, strictly speaking, representing < 2 MiB. The issue is with the decimal separator, that should be "," instead of ".". kernel-4.13.6-200.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-74d659e9da kernel-4.13.6-100.fc25 has been submitted as an update to Fedora 25. https://bodhi.fedoraproject.org/updates/FEDORA-2017-521bb0d538 kernel-4.13.6-100.fc25 has been pushed to the Fedora 25 testing repository.
