  • goconserver - A new console service to replace conserver

    With this release, goconserver is packaged in xcat-dep and is installed as part. of xCAT install/update. The following table shows the corresponding commands between the two services:

    purpose goconserver conserver
    start/stop service service goconserver start/stop service conserver start/stop
    create console files makegocons makeconservercf
    clean up invalid consoles makegocons -C makeconservercf -C
    list console connection status makegocons -q

    goconserver also allows for the ability to write console logs to TCP/UDP ports, configure this in /etc/goconserver/server.conf.

  • OpenBMC Python Framework (Beta) - Feedback is appreciated

    Please treat this as Beta as we are still working out some of the framework issues

    An new Python-based framework is introduced with this release of xCAT which improves the response time significantly for xCAT commands issued against OpenBMC REST API. This framework has dependencies on Python libraries that may not be available from the OS distribution.

    See this reference documentation for supported more information.

  • New project: xcat2/xcat-inventory(Alpha) - An inventory tool to manipulate xCAT configuration data

    This tool enables cluster administrators to:

    • manage xCAT cluster configuration under source control
    • define and create an xCAT cluster more easily
