Description of problem: The OFV parser tries to read the VM ID attribute from the first <Section> tag in the file. If the VM is part of an affinity group, the <Section> containing affinity information is before the <Section> with VM ID. This causes the parsing to fail and the agent crashes. The error is: MainThread::ERROR::2018-02-14 11:23:05,214::hosted_engine::434::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(start_monitoring) Unhandled monitoring loop exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 431, in start_monitoring self._monitoring_loop() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 450, in _monitoring_loop for old_state, state, delay in self.fsm: File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/fsm/machine.py", line 127, in next new_data = self.refresh(self._state.data) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/state_machine.py", line 123, in refresh ] = self.hosted_engine.min_memory_threshold File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 184, in min_memory_threshold return int(self._config.get(config.VM, config.MEM_SIZE)) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/env/config.py", line 213, in get self._load_config_files(dict([(type, self._dynamic_files[type])])) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/env/config.py", line 201, in _load_config_files self.refresh_local_conf_file(config_type) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/env/config.py", line 385, in refresh_local_conf_file result = refresh_method() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/env/config.py", line 515, in refresh_vm_conf content_from_ovf = self._get_vm_conf_content_from_ovf_store() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/env/config.py", line 443, in _get_vm_conf_content_from_ovf_store conf = ovf2VmParams.confFromOvf(heovf) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/ovf/ovf2VmParams.py", line 298, in confFromOvf vmConf = toDict(ovf) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/ovf/ovf2VmParams.py", line 222, in toDict vmParams['vmId'] = tree.find('Content/Section').attrib[OVF_NS + 'id'] File "lxml.etree.pyx", line 2272, in lxml.etree._Attrib.__getitem__ (src/lxml/lxml.etree.c:55336) KeyError: '{http://schemas.dmtf.org/ovf/envelope/1}id' Version-Release number of selected component (if applicable): ovirt-hosted-engine-ha 2.2.2-1.el7.centos How reproducible: 100% Steps to Reproduce: 1. Create an affinity group containing the HE VM. 2. Edit the HE VM, so the new OVF is saved to the storage domain. (For example, change maximum memory) 3. Wait a while and look to the HA agent logs Actual results: The agent keeps crashing with the above error. Expected results: The agent starts normally.
