I’m running some test ovirt environment. I have 3 hosts in a cluster/datacenter, about 90 vms on them. For the means of testing I have been adding multiple VLAN’s to hosts (about 300 at this point). And I’m having trouble with firewalld – its stopped reacting to any firewall-cmd commands. While NFT is working, yet it takes about 2+ minutes to print all rules.

I have tried adding .conf file in dbus’s system.d folder (/etc/dbus-1/system.d), like on screenshot: enter image description here
But that produced no effect, timeout is still 25 seconds. I am reading dbus daemon manual, but I can’t understand how to make a correct change to a specific firewalld service. Any help will be greatly appreciated.
Question: is it possible to change default 25 second timeout for dbus? Specifically for firewalld, preferably.
