subnets
by eevans＠digitaldatatechs.com 05 Mar '20

05 Mar '20

I have a network in place with several subnets, one for iscsi and one for virtual pbx and VoIP phones. I use the iscsi in Ovirt, but I cannot get Ovirt to recognize and use the physical vlan 3 network for phones. If I add it and the subnet, Ovirt will make give it an IP, but it's an isolated network with no connectivity to the other vm's or the Internet. I have read several topics on this but I can't get it to work properly. Any help would be appreciated. Thanks.

Debian 10 template - cloud init not working
by Sakari Poussa 05 Mar '20

05 Mar '20

Hi, I have tried centos7 & 8, debian 9 and ubuntu 18.04 template based VMs with cloud init (Initial run/use cloud init) and they all work as expected. However, the debian 10 template based VM seems *not* to execute the cloud init at all. It boots but hostname is not set and users / password are not set. You can't log in since there is no users and passwords/keys. Is this a known issue? Or am I missing something? The templates are from ovirt-image-repository storage domain. I have also created newer debian 10.3.0 template via ovirt.image-template ansible role. Results are the same. I am running ovirt 4.4-pre. Thanks, Sakari

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

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. HH, Gianluca
