Notes:

  • 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.

Restrictions and Known Issues

Issue #5121 rspconfig failed to set bmc ip etc in some specific condition

Issue #3513 For the latest xCAT-genesis-base, the mlx4_en driver 2.2-1 (Feb 2014) is included, it can not support Mellanox Ethernet NIC that need driver newer than 2.2-1, for more information, please reference build genesis locally with latest RH MN

Issue #5057 This issue cannot be reproduced, and the work around is : check the bmc state use rflash <node> -l, if the target firmware state is Active(+), execute rpower <node> boot to reboot the host and let new firmware take effect.

Issue #3284 While selinux on KVM host was reconfigured from enforcing to disabled, rpower failed to power previous created KVM guest on
