Hi, I have been seeing random failures of tests in different projects caused by vdsm monitoring.
I need someone from vdsm to please help debug this issue. >From what I can see, the test suspend/resume vm failed because we could not query the status of the vm on the host. you can see full log from failed tests here: https://jenkins.ovirt.org/job/ovirt-master_change-queue-tester/10208/artifact/basic-suite.el7.x86_64/test_logs/basic-suite-master/post-004_basic_sanity.py/ Here are the errors that I can see in the vdsm which seem to suggest that there is an issue getting stats on the vm which was suspended and caused the failure of the test: 2018-09-11 00:40:05,896-0400 INFO (monitor/c1fe6e6)
