xCAT Genesis Base¶
Note: Please rebuild xCAT-genesis-base
with xCAT-genesis-builder
version equal and newer than 2.13.10 before updating xCAT 2.13.10 and higher.
xCAT ships a xCAT-genesis-base
package as part of xcat-deps. This is a light-weight diskless linux image based on Fedora (Fedora26, currently) that is used by xCAT to do hardware discovery.
To support the Power9 hardware, changes are made to the kernel in the Red Hat Enterprise distribution that are not yet available in the Fedora kernels. Without that support, running the scripts in xCAT discovery caused segmentation faults described in this issue: https://github.com/xcat2/xcat-core/issues/3870
Work-around¶
xCAT cannot ship a kernel based on RHEL distribution, so the customer needs to build a version of the xCAT-genesis-base
on-site using a server running Red Hat Enterprise Linux.
