From: Dave Young on gitlab.com https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1171#note_615911272 Hi Kairui, it worth to say more about the reason of the update from 1G-4G to 0G-4G: * originally we have another RHEL only patch to round up the memblock collected system ram size by 128M because the memblock total size usually less than actual dimm size. Moving to 0-4G we can safely work without that patch. * the RHEL installtion minimum mem requirement is 1.5G for RHEL8, so we expect this will not have extra adding impact for small memory systems. But anyway if virt people can confirm about the minimum memory requirement is >=1G it would be great. _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
