note

...

  • If Out Of Memory (OOM) killer is used, it is strongly recommended to set the "OOM global status" and "Charon VM process killing prevention" to enabled from the "Preferences" option rather than disabling OOM at global level as this option does not work in 100% of the cases. The preferences option will be updated on next release to only prevent OOM from killing Charon at process level.

September, 17th 2018 - kit version 1.49

...

  • Support of Charon-AXP and Charon-VAX V4.9 build 194-02 and above
  • Removed support for Charon-AXP V4.5
  • Log monitoring updated for Charon-AXP and Charon-VAX V4.9 syntax change.
  • When using the "vmlist" command, if a daemon related to the license driver is missing, an alert is displayed.
  • Alerts management
    • It is now possible to disable the alerts sent if the hardware specifications of the Linux server are below the recommended ones from the "Alerts management" menu option. Messages will still be present in the log file but the alert will not be sent.
    • It is possible to disable/enable(default) the immediate alerts sent on USB dongle disconnection/connection
    • If the installed version is V4.9 or above, an option is added to reduce the number of warning messages sent on license dongle removal.
  • When using command lines like vmstart, vmstop, vmcfg and vmconsole, the latest virtual machine name used is stored so that next commands do not need the configuration file name as a parameter. This is useful when there's more than one virtual machine on the server. If there's only one, no need to specify the configuration file name
    Previously:
    # vmstart pluto
    # vmconsole pluto
    Now:
    # vmstart pluto
    # vmconsole
  • Display change in the list of virtual machines:
    • Layout reviewed for ease of reading
    • A warning is displayed if the root password has expired. On Red Hat Enterprise Linux 6.x this can prevent the virtual machine from starting.
    • Emulator and configuration file are now separated for better readability
    • The virtual machine selected from command lines mentioned above is identified with a star in the virtual machines list instead of a dash
    • If a pre-start script is defined, the first 3 lines executed before the virtual machine starts are displayed
    • If the log full path is not specified for a virtual machine an alert is displayed (full path is mandatory for log monitoring)
    • If the virtual machine is active and its log is monitored and the operating system uses 'systemd' (RHEL 7.x and CentOS 7.x) and the installed Charon version is V4.9 and above, the license status is displayed (license found, communication lost/restored, connection lost/application will stop, license expiration information)
  • Option added to restart all log monitoring services from the "Manage monitored guests logs" menu option, useful in case of kit upgrade.
  • Syntax highlighting updated for 'vim' and 'gvim' to highlight the configuration file displayed in the log
  • Show Host Information:
    • Option updated to display the content of the prestart script if defined
    • Highlight updated for the configuration file displayed in the log file for Charon-AXP and Charon-VAX V4.9
    • Added "lscsi -g" output in the Storage part
  • The "Request for new license or license update (send C2V file)" option has been updated for the new features provided with recent kits: if the c2v file can be generated for different keyids, one c2v file will be generated per keyid instead of one c2v file for the 1st license found. The zip file sent via email will contain all the c2v files generated.
  • How-to setup an ssh trust between Linux and Tru64 readme file has been updated in the "Create/Edit guest stop script" menu option and now explains what has to be done if a "no matching cipher found" message is displayed when executing an ssh command from the Linux server to the Tru64 one.
  • Preferences: added an option to add a separator when displaying defined virtual machines (default is none).
  • When starting a virtual machine, if a network interface defined in the configuration file has an IP address, it is automatically disconnected using the "nmcli dev disconnect (iface) <nic>" interface command and a warning alert is sent.
  • Option added in the menu to open the Sentinel Admin Control Center.

Important notes

  • If you're upgrading the toolkit, all the services monitoring the virtual machines logs have to be restarted from the "Manage monitored guests logs" menu option. The aksusbd log monitoring has to be restarted too. This does not affect running virtual machines.
  • The Charon-AXP/VAX version 4.9 provides a new syntax for OPA0 settings. Please note due to the detached process mechanism, no one terminal application can be started automatically thus the 'application' parameter must not be used.
  • The license monitoring within Charon-AXP and Charon-VAX V4.9 versions will provide much more information in the log than in previous versions. More alerts will then be sent in case of license switch (main/backup) or removal.

October, 23th 2017 - kit version 1.47

Important notes

  • In case of kit upgrade, the log monitoring service will have to be restarted for all virtual machines on the server (this does not affect running virtual machines)
  • Due to a bug in our Wiki and its PDF exporter some links inside the PDF document are pointing to the online version of the document instead of the document itself
