we recently added a bunch of firewalls around vlans where our VMs live and it may be causing a lot of confusion to ovirt management node? Though I don't know why firewall would cause intermittent problems.
We see a lot of errors like: (in engine.log) 2022-07-28 19:39:47,923-07 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (ForkJoinPool-1-worker-1) [] VM '6e177451-d43f-4e 91-85ad-6b8f3bcfc4ad'(epayfraud2.j2noc.com) moved from 'NotResponding' --> 'Up' ... 2022-07-28 19:39:53,676-07 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineSch eduled-Thread-58) [] EVENT_ID: VM_NOT_RESPONDING(126), VM epayfraud 2.j2noc.com is not responding. ... 2022-07-28 19:40:36,189-07 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (ForkJoinPool-1-worker-10) [] VM '6e177451-d43f-4e91-85ad-6b8f3bcfc4ad'( epayfraud2.j2noc.com) moved from 'NotResponding' --> 'Up' I guess my first question is how does ovirt determine if VM is up or not, is it the management node or the host VM is running on and what ports does it use to determine health?
