When oVirt was deployed in our environment by previous engineers, the DWH was installed as Basic. I would like to change this to Full, to get the daily stats, as this is now empty due to the scale. If it's completely empty, perhaps there is some other problem, not the scale. To further debug this, check that both the engine and dwh access the same database (this should be ok by default, but perhaps you used non-defaults) by checking the credentials they use in their conf files: grep DWH_DB /etc/ovirt-engine/engine.conf.d/*conf grep DWH_DB /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/*conf You might also check /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log .

Changing the Data Warehouse Sampling Scale
by anton.louw＠voxtelecom.co.za 04 Mar '20

04 Mar '20

Hi Everybody, I have a question. When oVirt was deployed in our environment by previous engineers, the DWH was installed as Basic. I would like to change this to Full, to get the daily stats, as this is now empty due to the scale. Is this just as simple as described in the following article: https://www.ovirt.org/documentation/data-warehouse/Changing_the_Data_Wareho… Are there any precautions I should take, and has anybody else ever done this before? Thanks a lot

Error when exporting virtual machine

Different cpu flags preventing live migration
by Gianluca Cecchi 02 Mar '20

02 Mar '20

Hello, I would like to share some problems that I'm finding on an environment based on RHV, but could impact also oVirt based environments. For my problems I'm working on an opened case to understand root cause. I have Dell R730 hypervisors (with Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz cpu) and some VMs configured for "customized" high performance. In the sense that I configure VM as high performance type and then: - I enable the graphical console (I remove the flag of headless Mode" in Console section); - In Host section I set for "Start Running On" Any Host in Cluster and allow manual and automating migration; - I also set HA in high availability section, accepting default values for leasing, resume behaviour, ecc.. These settings however have the effect to leave enable the flag related to "Pass-Through Host CPU" in Host section. I noticed that with same Bios, ecc with kernel in 4.3.8 (that seems equal between oVirt and RHV): [g.cecchi@ov200 ~]$ uname -r 3.10.0-1062.12.1.el7.x86_64 [g.cecchi@ov200 ~]$ I have this cpu flag set: invpcid_single Instead on the same host in 4.3.5 (eg kernel 3.10.0-1062.el7.x86_64) the flag is not set. This creates problem during upgrade from 4.3.5 to 4.3.8 because initially I empty one host and update it, but then I cannot live migrate back the VMs to update the other one, due to the pass-through flag set, that requires exact set of flags. So crosscheck on a test environment in case you have the "Pass-Through Host CPU" set in Host section for any critical VM you cannot shutdown. BTW: the flag is somehow tricky to remove if you set the VM as High Performance type; you have to: edit VM --> Host Start Running On --> change to select a specific host among the available ones Now you can remove the "Pass-Through Host CPU" flag --> remove it Start Running On --> change again to "Any Host in Cluster" Save Now you can live migrate this "customized" High Performance VM But the problem is that if the VM is running, you have to shutdown it to get the change in effect.

Hi Marko, I guess you can use distributed-replicated volumes and oVirt cluster with host triplets.

1-Host home setup question
by Christian Reiss 28 Feb '20

28 Feb '20

Hey folks, for a home-vm setup (1 host): If I setup the Hardware with CentOS7, configure Gluster et all by hand and get things up and running this way: Would it be a viable option to install the ovirt engine directly on the host as well? This would save some overhead. Or is running ovirt engine directly inside an ovirt host, even using CentOS (not the node) not recommended and will break things? -- with kind regards, mit freundlichen Gruessen, Christian Reiss
