We currently have the min ram set at 512 MB: <resources arch="all"> <minimum> <n-cpus>1</n-cpus> <ram>536870912</ram> </minimum> <recommended> <cpu>400000000</cpu> <ram>1073741824</ram> <storage>9663676416</storage> </recommended> </resources> Based on this: https://access.redhat.com/articles/rhel-limits 512 MB is only acceptable for i386, x86_64 requires 1 GB min and PPC wants 2 GB. So we clearly need to update the RHEL6 limits both minimum and recommended. Could you submit a patch for the various RHEL XML files to update these limits.
