  • For provisioning x86 nodes, pull request https://github.com/xcat2/xcat-core/pull/6772 added code to skip the elilo bootloader, if possible. If you experience problems provisioning x86 nodes without elilo, please open an issue. As a workaround, you can force the use of elilo by adding an explicit return 0 from /opt/xcat/lib/perl/xCAT_plugin/xnba.pm:has_efistub(). When using this workaround on an Ubuntu xCAT management server, an updated elilo-xcat package is also required. To install the updated package, download it with: wget https://xcat.org/files/xcat/repos/apt/devel/xcat-dep/pool/main/e/elilo-xcat/elilo-xcat_3.14-5_all.deb and then apt-get install ./elilo-xcat_3.14-5_all.deb prior to provisioning x86 compute nodes.
