Release LoadGen Api, Appliance and MCP Server: 1.0.0.11966

LoadGen General

[#8948] Datasources on the Service Levels tab could become impossible to remove: deleting the active datasource was always refused with 409 Conflict ("Cannot delete the active datasource…"), and on a view with only a single datasource there was nothing to switch to first, so an unreachable entry that had been edited and re-activated was stuck for good. DELETE /config/datasources/{name} now succeeds for the active datasource as long as it is not backing a running test or monitoring execution; in that case the delete is still refused with a clearer message asking to stop the run or switch to another datasource first. After an active datasource is removed, LoadGen automatically re-resolves which datasource is active and rebuilds the data connection, so no manual switch is needed. Pairs with a LoadGen FrontEnd update that surfaces the per-row Delete button in the web interface.

Appliance could become unbootable after an update. On some appliances the next reboot after an update dropped to the BusyBox (initramfs) shell with "ALERT! /dev/mapper/ubuntu--vg-ubuntu--lv does not exist", because an update could rebuild the Linux boot image without its storage drivers. Boot images are now validated, regenerated and backed up automatically, so a bad build can never replace a working one. Existing appliances with an affected boot image are detected and repaired automatically on the next agent update, before any reboot is required.
