Single-Host Hyperconverged set-up not showing gluster volumes
by Guillaume Pavese 05 Feb '20

05 Feb '20

Hi, I setup a new oVirt hosted engine instance on a mono-server DC/Cluster; I deployed gluster on the Hypervisor with cockpit and then the hosted engine with hosted-engine --deploy It seems to be working, but IO perfs are not good (10MB/s) on a 4x SAS disks raid5. So I wanted to check if the optimize for virt-store settings had been applied (I remember that there used to be a bug for at least most of 4.2.x) However, event if I see the data domains in "Storage >> Storage Domains" and in "Storage >> Data Centers", "Storage >> Volumes" is empty. Is that normal? Any idea if there is anything to do to see the gluster volumes there and manage theirs options?

Hi all, I noticed that dpdk is experimental support in ovirt 4.2, is it support officially in later version? And what's the shortage or insufficient of dpdk in ovirt 4.2? Thank you!

The vdsm logs are not the correct ones.

Hello, I am having this same issue and have inserted the three new lines into /lib/python2.7/site-packages/ansible/modules/cloud/ovirt/ovirt_network.py yet it still occurs. I have rebooted the oVirt Node host. Do I need to insert the fix elsewhere or take other action to properly apply this fix? Thank you very much, Diamond Tours, Inc.

oVirt API - New vm on specified storage
by Tommaso - Shellrent 04 Feb '20

04 Feb '20

Hi to all. we are tring to create a new VM via API, but we are unable to select the desidered storage where to deploy it. We make a call like this: CALL: POST /ovirt-engine/api/vms?clone=true Data: {"cpu":{"topology":{"sockets":1,"cores":4,"threads":1}},"memory":4294967296,"memory_policy":{"guaranteed":4294967296,"max":4294967296},"disk_attachments":[{"disk":{"id":"925c999e-536f-4905-bc54-5cf64477a3a7","format":"cow","storage_domains":[{"id":"a772c71a-bd7b-4898-9497-120dcd853d96"}]}}],"name":"apitest.domain.com","fqdn":"apitest.domain.com","cluster":{"id":"890681f6-e0fe-11e9-81b5-0200007c8e05"},"template":{"id":"45da14a2-7f6f-43d9-9481-19a2034700fe"}} But the reply is: Reply HTTP 400 { "detail" : "For correct usage, see: https://XXXXXXX/ovirt-engine/apidoc#services/vms/methods/add", "reason" : "Request syntactically incorrect." } Have someone some suggestion or good example??

memory overcommit in oVirt
by yam yam 04 Feb '20

04 Feb '20

Hello, I thought memory overcommit feature in oVirt utilizes host's overcommit features by manipulating kernel variables like vm.overcommit_ratio, vm_overcommit_memory. but, I've just confirmed that those variables didn't change at all. I wonder if oVirt's overcommit really has nothing to do with that of host and if so, how does oVirt manage memory overcommit.
