Hi, While running a test case of adding hosts on ovirt system tests there was a failure while the following command was executed: vdsm-tool configure --force On libvirtd log I found this error: 2021-12-17 00:11:41.753+0000: 28031: error : virNetTLSContextNew:732 : Unable to generate diffie-hellman parameters: Error in public key generation. How would you suggest to debug this failure? attaching libvirtd & journalctl logs libvirt version: 7.10.0, package: 1.module_el8.6.0+1046+bd8eec5e Thanks, Dana The error from host deploy log: "2021-12-17 01":"11":"45 CET - fatal":[ ost-basic-suite-master-host-0 ]:"FAILED! =>"{ "changed":true, "cmd":[ "vdsm-tool", "configure", "--force" ], "delta":"0:00:06.908971", "end":"2021-12-17 01:11:42.815057", "msg":"non-zero return code", "rc":1, "start":"2021-12-17 01:11:35.906086", "stderr":"Error: ServiceOperationError: _systemctlStart failed\nb'Job for libvirtd.service failed because a fatal signal was delivered causing the control process to dump core.\\nSee \"systemctl status libvirtd.service\" and \"journalctl -xe\" for details.\\n' ", "stderr_lines":[ "Error: ServiceOperationError: _systemctlStart failed", "b'Job for libvirtd.service failed because a fatal signal was delivered causing the control process to dump core.\\nSee \"systemctl status libvirtd.service\" and \"journalctl -xe\" for details.\\n' " ], "stdout":"\nChecking configuration status...\n\nlvm is configured for vdsm\nCurrent revision of multipath.conf detected, preserving\nlibvirt is already configured for vdsm\nSUCCESS: ssl configured to true.
