Description of problem: I'm getting the warning: "Available swap memory of host lago-basic-suite-master-host0 [615 MB] is under defined threshold [1024 MB]." every 30 minutes. There's no point in that, and with more hypervisors I would have received a lot more. Once a day should suffice. Version-Release number of selected component (if applicable): Master How reproducible: Always. Steps to Reproduce: 1. Run ovirt-system-tests, which currently does not set enough swap for its VMs. 2. See that every 30 minutes you'll get such a warning.
I tend to agree. The question is whether this should also apply to other values such as: VDS_HIGH_NETWORK_USE VDS_HIGH_CPU_USE VDS_HIGH_SWAP_USE VDS_LOW_SWAP I guess maybe only the last two should change.

I don't think so - they are dynamic in nature - depending on the memory pressure, they'll come and go.
Verify with: 4.1.1.7-0.1.el7 set swap to 1 GB and load host memory, check the log for 2 hours. message appear only one time.
