i know, i know, i shouldnt spam this list ;) but after some tests i have tried to change the nova-conf (/etc/nova/nova.conf) and edit some values: [default] libvirt_cpu_mode = "custom" // none -> costom libvirt_cpu_model = "EPYC-IBRS" // insert this line [libvirt] cpu_mode = "custom" // none -> custom cpu_model = "EPYC-IBRS" // insert this line but after reboot my compute-node, some auto-config logic is reconfigure this config-file and "[libvirt]" part the option "cpu_mode" is back to "none" and "cpu_model" is deleted completly :( is there any way to prevent or configure this auto-config? volker... ________________________________________ Von: von Hoesslin, Volker [Volker.Hoesslin@swsn.de] Gesendet: Freitag, 18.
