I had to replace the DNS server in my network so I want to update the DNS address on each host so in oVirt web interface I go to Compute > Host > Hostname > Network Interfaces > Setup Host Networks Right there I click on the edit button of the vlan for networking, check out (host ip address is static), DNS configuration, check DNS configuration, Type DNS ip address and click ok to save change. I got message: Error while executing action HostSetupNetworks: Unexpected Exception. Into engile.log found message "Operation not permitted" related to this action despite that was executed with my user account (wint admin privileges) and same message was returned using admin@internal user. 2021-01-20 11:35:31,579-05 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] START, HostSetupNetworksVDSCommand(HostName = hyp10.eboss, HostSetupNetworksVdsCommandParameters:{hostId='39c05625-7b59-4a38-a5a9-5d556ae1fe18', vds='Host[hyp10.eboss,39c05625-7b59-4a38-a5a9-5d556ae1fe18]', rollbackOnFailure='true', commitOnSuccess='true', connectivityTimeout='120', networks='[HostNetwork:{defaultRoute='true', bonding='false', networkName='tgcs182vlan', vdsmName='tgcs182vlan', nicName='eno1', vlan='null', vmNetwork='true', stp='false', properties='[]', ipv4BootProtocol='STATIC_IP', ipv4Address='10.89.182.10', ipv4Netmask='255.255.255.0', ipv4Gateway='10.89.182.1', ipv6BootProtocol='AUTOCONF', ipv6Address='null', ipv6Prefix='null', ipv6Gateway='null', nameServers='[NameServer:{address='10.89.182.204'}, NameServer:{address='10.89.176.71'}]'}]', removedNetworks='[]', bonds='[]', removedBonds='[]', clusterSw itchType='OVS', managementNetworkChanged='false'}), log id: 23059843 2021-01-20 11:35:31,582-05 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] FINISH, HostSetupNetworksVDSCommand, return: , log id: 23059843 2021-01-20 11:35:35,665-05 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Unexpected return value: Status [code=-32603, message=Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}] 2021-01-20 11:35:35,665-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Failed in 'HostSetupNetworksVDS' method 2021-01-20 11:35:35,666-05 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Unexpected return value: Status [code=-32603, message=Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}] 2021-01-20 11:35:35,673-05 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM hyp10.eboss command HostSetupNetworksVDS failed: Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'} 2021-01-20 11:35:35,673-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Error: VDSGenericException: VDSErrorException: Failed to HostSetupNetworksVDS, error = Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}, code = -32603 2021-01-20 11:35:35,673-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Command 'HostSetupNetworksVDSCommand(HostName = hyp10.eboss, HostSetupNetworksVdsCommandParameters:{hostId='39c05625-7b59-4a38-a5a9-5d556ae1fe18', vds='Host[hyp10.eboss,39c05625-7b59-4a38-a5a9-5d556ae1fe18]', rollbackOnFailure='true', commitOnSuccess='true', connectivityTimeout='120', networks='[HostNetwork:{defaultRoute='true', bonding='false', networkName='tgcs182vlan', vdsmName='tgcs182vlan', nicName='eno1', vlan='null', vmNetwork='true', stp='false', properties='[]', ipv4BootProtocol='STATIC_IP', ipv4Address='10.89.182.10', ipv4Netmask='255.255.255.0', ipv4Gateway='10.89.182.1', ipv6BootProtocol='AUTOCONF', ipv6Address='null', ipv6Prefix='null', ipv6Gateway='null', nameServers='[NameServer:{address='10.89.182.204'}, NameServer:{address='10.89.176.71'}]'}]', removedNetworks='[]', bonds='[]', removedBonds='[]', cluster SwitchType='OVS', managementNetworkChanged='false'})' execution failed: VDSGenericException: VDSErrorException: Failed to HostSetupNetworksVDS, error = Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}, code = -32603 2021-01-20 11:35:35,673-05 INFO [org.ovirt.engine.core.bll.network.host.HostSetupNetworksCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Host setup networks finished.
