To use RHEL 8 with xCAT, RHEL 8.0.0 RC 2 is supported ONLY.
If deploy RHEL 8 compute nodes is intended after migrate from a previous xCAT installation, manually run
chdef -t site xcatsslversion=after xCAT migration. Otherwise, problems will be hit when deploy RHEL 8 compute node. #5794 #5798 #6061 #6090 And this kind of migration is supported on RHEL 7 ONLY. #577
There is no plan to support xCAT Software Kits function on RHEL 8.
- To use xcat-openbmc-py3 on RH8, please reference the steps deploy xcat-openbmc-py3 on RH8 for more information.
