Running self-hosted ovirt-node 4.2 Does anyone know what could be the issue for this behavior ? Thank you ! -- Best regards, Leo David

Question re: MaxFreeMemoryforOverUtlized and MinFreeMemoryforUnderUtilized
by Alastair Neil 14 Jun '18

14 Jun '18

Can someone clarify these setting for me, I am having difficulty parsing what exactly they mean. They seem to me to be backwards. If I wish to set a threshold at which I want my host to be consider over utilized, not schedule any new VMs, and migrate VMs away, then surely I should specify a minimum threshold of free memory. I.E. if free memory drops below my threshold (OR memory use exceed a maximum threshold) migrate VM's off of this system. Conversely if a system is underutilized I should set a maximum threshold of free memory (Or minimum used memory). Thanks, --Alastair

Centos7.5 or Ovirt node for new hci build?
by Jayme 13 Jun '18

I'm about to build a 3 host Ovirt hyperconverged cluster and was wondering if it's recommended to use straight up Centos or would Ovirt node be a better choice? Thanks

Useless disk statistics API
by Hari Prasanth Loganathan 13 Jun '18

13 Jun '18

Hi Team, I use the following API to get the disk statistics as per the oVirt rest API documentation. http://ovirt.github.io/ovirt-engine-api-model/4.2/#types/disk/links/statist… https://172.30.X.X/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d8446… { "statistic": [ { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e", "id": "f78c8adf-23f9-4f52-a29b-0de3d844652e" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e/statistics/33b9212b-f9cb-3fd0-b364-248fb61e1272", "id": "33b9212b-f9cb-3fd0-b364-248fb61e1272" }, { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e", "id": "f78c8adf-23f9-4f52-a29b-0de3d844652e" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" } ] } Unfortunately, the values are always coming as '0'. *Steps to reproduce :* 1) I logged into the VM console and run the following command to copy the file and I see the write rate is 300mb/sec dd if=/dev/zero of=/dev/null 2) During this time, I am trying to execute this API and receiving as 0 always. Is this API useless? Thanks, Hari
