  • 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

Key Issues Resolved

Issue #4840 verify the kdump on pegas 1.x diskless

Issue #4820 error message improvement when adding users in hierarchical configuration

Issue #4811 not set domain in site table will cause dhcp service failed to start

Issue #4754 confignetwork -s prevents nodes to be deployed

Issue #4743 setroute doesn't work for DHCP interfaces

Issue #4735 enhance Installing a New Kernel in the Diskless Image doc

Issue #4652 bmcdiscover command will not able to find Boston node

Issue #4615 Enhance output of rflash -c for ipmi controlled machines

Issue #4582 Install loops forever, no easy way to trace install progress of diskful nodes

Issue #4629 For sites that would like to forward to their own DNS servers, the site table includes the 'forwarders' attribute to allow for this. If the site internal DNS resolves RFC1918 addresses, xCAT dns doesn't work.

Restrictions and Known Issues

Issue #4929 xcatd failed to start in rhels7.5-snap2 diskless service node due to writing rsyslog failed

Issue #4936 Python framework stops responding, commands reply empty response

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