[ovirt-users] 'python-nftables' failed. There is a big problem with Firewalld and openvswitch on Centos 8.3

I have deployed a new cluster on versions: 3 Hosts: Centos 8.3 and last update Ovirt: 4.4.4.7-1.el8 Cluster properties: switch - OVS; Firewall - Firewalld During the initial deployment of the host in such a cluster, everything is successfully installed, all virtual networks and bridges are created, and the host is activated. But after that, Firewalld does not work correctly, for example, when executing the command firewall-cmd --reload Issued by: Error: COMMAND_FAILED: 'python-nftables' failed: JSON blob: {"nftables": [{"metainfo": {"json_schema_version": 1}}, {"add": {"table": {"family": "inet", "name": "firewalld_policy_drop"}}}, {"add": {"chain": {"family": "inet", "table": "firewalld_policy_drop", "name": "filter_input", "type": "filter", "hook": "input", "prio": 9, "policy": "drop"}}}, {"add": {"chain": {"family": "inet", "table": "firewalld_policy_drop", "name": "filter_forward", "type": "filter", "hook": "forward", "prio": 9, "policy": "drop"}}}, {"add": {"chain": {"family": "inet", "table": "firewalld_policy_drop", "name": "filter_output", "type": "filter", "hook": "output", "prio": 9, "policy": "drop"}}}, {"add": {"rule": {"family": "inet", "table": "firewalld_policy_drop", "chain": "filter_input", "expr": [{"match": {"left": {"ct": {"key": "state"}}, "op": "in", "right": {"set": ["established", "related"]}}}, {"accept": null}]}}}, {"add": {"rule": {"family": "inet", "table": "firewalld_policy_drop", "chain": "filter_forward", "expr": [{"match": {"left": {"ct": {"key": "state"}}, "op": "in", "right": {"set": ["established", "related"]}}}, {"accept": null}]}}}, {"add": {"rule": {"family": "inet", "table": "firewalld_policy_drop", "chain": "filter_output", "expr": [{"match": {"left": {"ct": {"key": "state"}}, "op": "in", "right": {"set": ["established", "related"]}}}, {"accept": null}]}}}]} Now all ansible-playbook ovirt starts to execute uncorrectly For example this error is thrown every time I try to reinstall the host: VDSM SMnode02 command CollectVdsNetworkDataAfterInstallationVDS failed: Internal JSON-RPC error: {'reason': ’management’} I understand that ovirt correctly executes scripts, and this problem is related to the applications Firewalld, openvswitch, NetworkManager. Is there some workaround so that at least ovirt can re-install hosts?
