Sorry Jiri, I don't have a self hosted engine add present so can't check which keys you can change but it says you can also append a configuration or answer file. I think any changes should persist over updates, the local changes have to be applied to each node whereas the shared configuration is applied when a new host is deployed.

Hello Paul, thanks for reply and for pointing me to RHV documentation. Shame on me, I forogot it exists and is well maintained and super relevant for oVirt. But in this case I am a bit lost. I can't find something relevant to my effort to modify HE vm's config to add the second NIC to it. Or do you mean I should change the location of vm.conf from /var/run location to something persistent and then modify this vm.conf as mentioned in that old post? For example, now I got this output for conf key [root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_shared conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_shared [root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_local conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_local Is it valid to change it to (for example) /etc/ovirt-hosted-engine/vm.conf and modify that file there? Is it safe for further updates, maintenance, etc.? Maybe the second question - which process creates vm.conf in /var/run path?
