Huge increase of CPU load on hosted engine VM after upgrade to 4.3.8 and cluster compatibility version
by Florian Schmid 06 Feb '20

06 Feb '20

Hi, I have upgraded yesterday one of our ovirt environments from 4.2.8 to 4.3.8. We have a hosted engine, 25 hosts and about 150 VMs running there. After upgrading the cluster compatibility version from 4.2 to 4.3, I have seen a huge increase of CPU load on the engine VM. The engine had 4 cores (16GB mem) and never had load issues, but after the upgrade, the system has a load of 6 and more. I have increased the CPUs to 8, because working in the UI was impossible. I have noticed, that the load always increase, when I load the VM UI tab, where now all VMs have the orange triangle with pending changes: Custom compatibility version The problem I have, is, that I can't reboot now all VMs, maybe in the next 3 or 4 weeks. Working now with the UI is quite problematic, because of the slowness. The engine VM was already rebooted, but didn't solve the problem. What logs do you need and is there a workaround available? I have some more oVirt environments to upgrade, all with even more VMs. BR Florian

oVirt MAC Pool question
by Vrgotic, Marko 06 Feb '20

06 Feb '20

Dear oVirt, While investigating and DHCP & DDNS collision issues between two VM servers from different oVirt clusters, I noticed that oVirt assigns same default MAC range for each of it’s managed clusters. Question1: Does oVirt-Engine keep separate place in DB or … for MAC addresses assigned per cluster or it keeps them all in same place? Question2: Would there be an harming effect on existing VMs if the default mac pool would be changed? Additional info: Self Hosted ovirt-engine – 4.3.4 and 4.3.7 ----- kind regards/met vriendelijke groeten Marko Vrgotic ActiveVideo

Dear community, I am trying to achieve the following: - create a regular user in oVirt environment; [DONE] - grant full access to a particular VM; [DONE] - grant privileges to create new VMs; [NOT OK] What I observe currently: - user sees his VM on "VM Portal" page and can edit its settings, this is fine; - user can not suspend the VM with the following error in engine.log: 2020-02-04 13:48:25,473Z INFO [org.ovirt.engine.core.bll.HibernateVmCommand] (default task-95) [d43167ef-894f-4281-9100-578bac65a3bb] Running command: HibernateVmCommand internal: false.

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?
