well, unless the entire network is without dhcp and get 169.254 addresses? livnat - thoughts? Do not forget this: guestIPs = 169.254.107.112 10.34.61.243 Both were reported! I think the GA should be loyal to what is configured on the guest, not reporting the Link-Local address potentially hides a problem instead of exposing it to the admin. > Do not forget this: > guestIPs = 169.254.107.112 10.34.61.243 > Both were reported! According to RFC 3927 [1], that defines the auto-allocation mechanism it is not recommended that IPv4 Link-Local addresses and routable addresses be configured simultaneously on the same interface. In this case the GA is reflecting the (bad) existing state. My take on this is that unlike the loop back IP address the Link-Local address is meaningful thus it should be reported by the guest agent.

Description of problem: Windows guest agent from 3.3.6 reported temporarily for a Windows 8 32bit guest following IPs: guestIPs = 169.254.107.112 10.34.61.243 169.254/16 should never be reported. it's dedicated when there's an issue with dhcp. -%- Thread-35892::DEBUG::2013-10-08 07:39:21,280::BindingXMLRPC::981::vds::(wrapper) return vmGetStats with {'status': {'message': 'Done', 'code': 0}, 'statsList': [{'username': '', 'memUsage': '33', 'acpiEnable': 'true', 'guestFQDN': u'jb-w8-x86.rhev.lab.eng.brq.redhat.com', 'pid': '2165', 'session': 'Unknown', 'displaySecurePort': u'5901', 'timeOffset': '3600', 'balloonInfo': {'balloon_max': '1048576', 'balloon_target': '1048576', 'balloon_cur': '1048576', 'balloon_min': '1048576'}, 'pauseCode': 'NOERR', 'disksUsage': [{u'path': u'c:\\', u'total': '21105733632', u'used': '7691403264', u'fs': u'NTFS'}], 'network': {u'vnet0': {'macAddr': '00:1a:4a:ca:60:9d', 'rxDropped': '0', 'rxErrors': '0', 'txDropped': '0', 'txRate': '0.0', 'rxRate': '0.0', 'txErrors': '0', 'state': 'unknown', 'speed': '1000', 'name': u'vnet0'}}, 'vmType': 'kvm', 'guestName': u'JB-W8-X86', 'elapsedTime': '93', 'memoryStats': {u'swap_out': '0', u'majflt': '0', u'mem_free': '696472', u'swap_in': '0', u'pageflt': '0', u'mem_total': '1048152', u'mem_unused': '696472'}, 'cpuSys': '1.93', 'appsList': [u'RHEV-Tools 3.3.6', u'RHEV-Serial 3.3.2', u'RHEV-SCSI 3.3.2', u'RHEV-Agent 3.3.4', u'RHEV-Block 3.3.1', u'RHEV-Balloon 3.3.2', u'RHEV-Spice-Agent 3.3.2', u'RHEV-QGA 3.3.2', u'RHEV-SSO 3.3.1', u'RHEV-Network 3.3.1'], 'guestOs': u'Win 8', 'displayType': 'qxl', 'status': 'Running', 'hash': '4908678487199624478', 'vmId': '4b8b55a8-1152-40a1-ba4c-346dac1ff2e8', 'displayIp': '0', 'displayPort': u'5900', 'clientIp': '', 'kvmEnable': 'true', 'disks': {u'vda': {'readLatency': '2993981', 'apparentsize': '3348824064', 'writeLatency': '6045740', 'imageID': '704ac65c-b82c-4c89-a1d1-8c68c8245761', 'flushLatency': '455129', 'readRate': '9160917.29', 'truesize': '3350413312', 'writeRate': '497775.94'}, u'hdc': {'readLatency': '0', 'apparentsize': '0', 'writeLatency': '0', 'flushLatency': '0', 'readRate': '0.00', 'truesize': '0', 'writeRate': '0.00'}}, 'monitorResponse': '0', 'statsAge': '0.36', 'cpuUser': '9.71', 'lastLogin': 1381217886.887325, 'guestIPs': u'169.254.107.112 10.34.61.243', 'netIfaces': [{u'hw': u'00:1a:4a:ca:60:9d', u'name': u'Red Hat VirtIO Ethernet Adapter', u'inet': [u'169.254.107.112', u'10.34.61.243'], u'inet6': [u'fe80::d43a:fd55:d36c:6b70', u'2620:52:0:223c:a178:7551:cceb:2ecc', u'2620:52:0:223c:d43a:fd55:d36c:6b70']}]}]} -%- Version-Release number of selected component (if applicable): 3.3.6 How reproducible: temporarily when VM starts but not always :) Steps to Reproduce: 1.??? 2. 3. Actual results: GA report both real IP and private ip dedicated to dhcp issue Expected results: either report only real IP or nothing Additional info: after next cycle 169.254/16 IP disappear!
