Hi all, We are using oBirt since 4.2. Config is 1Gb or 10G for VM ext network and 40Gb IB for Starage and VM Migration. We are testing 4.4 and 4.4.0 at the moment. 2 problems - Major problem is that i can't assign IB netwrok to IB bond i got - "Error while executing action HostSetupNetworks: Unexpected exception" VDSM.log 2020-07-11 15:33:39,147+0300 INFO (jsonrpc/1) [api.network] START setupNetworks(networks={'IB': {'netmask': '255.255.255.0', 'bonding': 'bond1', 'ipv6autoconf': False, 'bridged': 'false', 'ipaddr': '172.17.21.101', 'dhcpv6': False, 'mtu': 65520, 'switch': 'legacy'}}, bondings={}, options={'connectivityTimeout': 120, 'commitOnSuccess': True, 'connectivityCheck': 'true'}) from=::ffff:172.16.21.201,33614, flow_id=fe589281-3171-41b4-b7aa-e28a4bbebe55 (api:48) 2020-07-11 15:33:40,088+0300 INFO (jsonrpc/1) [api.network] FINISH setupNetworks error=MAC address cannot be specified in bond interface along with specified bond options from=::ffff:172.16.21.201,33614, flow_id=fe589281-3171-41b4-b7aa-e28a4bbebe55 (api:52) 2020-07-11 15:33:40,088+0300 ERROR (jsonrpc/1) [jsonrpc.JsonRpcServer] Internal server error (__init__:350) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/yajsonrpc/__init__.py", line 345, in _handle_request res = method(**params) File "/usr/lib/python3.6/site-packages/vdsm/rpc/Bridge.py", line 198, in _dynamicMethod result = fn(*methodArgs) File "<decorator-gen-480>", line 2, in setupNetworks File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 1548, in setupNetworks supervdsm.getProxy().setupNetworks(networks, bondings, options) File "/usr/lib/python3.6/site-packages/vdsm/common/supervdsm.py", line 56, in __call__ return callMethod() File "/usr/lib/python3.6/site-packages/vdsm/common/supervdsm.py", line 54, in <lambda> **kwargs) File "<string>", line 2, in setupNetworks File "/usr/lib64/python3.6/multiprocessing/managers.py", line 772, in _callmethod raise convert_to_error(kind, result) libnmstate.error.NmstateValueError: MAC address cannot be specified in bond interface along with specified bond options 2nd problem - IB bond not working after reboot - theres is no bond1 insterface at all (my solution is to restart network) This is not very important as VDSM will change config after Adding bond to oVirt. P.S. I Got 100% same config with same cards and samу bond config on 4.3 - everething is wotking fine.
