Type of CPU for AMD EPYC
by Erick Perez 18 Dec '18

18 Dec '18

Hi, currently imsetting up two hosts for virt and one host for storage. All hosts have AMD EPYC 7281 16-Core Processor as the single socket CPU on it. What type of CPU should I tell ovirt that it has? Currently on latest ovirt engine, it only shows AMD Opteron G1,G2,G3,G4,G5 and no mention of EPYC. suggestions?

engine mails about FSM states
by fsoyer 17 Dec '18

17 Dec '18

Hi, I don't find revelant answer about this. Sorry il this was already asked. I receive randomly (one or two tims a week, differents hours) 3 mails with this subjects : first : ovirt-hosted-engine state transition StartState-ReinitializeFSM second : ovirt-hosted-engine state transition ReinitializeFSM-EngineStarting third : ovirt-hosted-engine state transition EngineStarting-EngineUp all at exactly the same time. The "events" in GUI doesn't indicate anything about this. No impact on engine or VMs. So I wonder what this messages means ? And, if case of just "info" messages, is there a way to disable them ? Thanks. -- Reagrds, Frank

Interface issue when using a macOS workstation
by Vineet Khandpur 15 Dec '18

15 Dec '18

Hello. Apologies if this has been asked before, but Google came up empty for me. Recently converted to a Macbook, I've noticed an issue with the oVirt interface. When in the Compute > Virtual Machines screen, when I'm trying to select multiple VMs, CMD+click doesn't work. I cannot select multiple machines at the same time. CNTL+click in macOS sends a right click to the interface, and no combination of OPTION/CONTROL/CMD works. Tried on Chrome, Firefox and Safari. SHIFT+click works on selecting multiple hosts when they are all in a row, but random select via CMD+click doesn't. A nudge in the right direction would be greatly appreciated. Thanks. vk -------------------------------- Vineet Khandpur UNIX System Administrator Information Technology Services University of Alberta Libraries +1-780-492-4718

Ovirt-host 4.3 working on Fedora 28 / RHEL 8!
by John Boero 14 Dec '18

14 Dec '18

Hi just a heads up because I like to live dangerously. Particularly with RHEL 8 being based on Fedora 28 it's nice to see a published repo for 4.3 on F28 again. I've been playing with it a bit and have gotten a F28 host successfully working on 4.3. There are some caveats. I've also tried running the engine on F28 but there seems to be something lacking in ovirt-host-deploy as engine 4.3 is never able to create the tarball for me. BUT I managed to get it working smoothly on a EL7 engine 4.2 deploying host 4.3. As there's still an unhealthy mix of NetworkManager.service and network.service, I had to make sure my main/management connection is the only one managed by NetworkManager. Having interfaces managed by both is always a fail (for obvious reasons). Also python3-firewall has deprecated python-firewall (python2) so I had to manually install those packages. Still RPM hates to have them both installed and updates continuously remove the deprecated python-firewall, so disable firewall config during host deploy and configure it manually. Magic! Very nice work, dev team. Looking forward to a fully smooth automated migration and support for python3-firewall and deprecated packages.

Memory usage inclines
by Tony Brian Albers 14 Dec '18

14 Dec '18

Hi guys, We have a small test installation here running around 30 vms on 2 hosts. oVirt 4.2.5.3 The hosts each have 512 GB memory, and the vms are sized with 4-8 GB each. I have noticed that over the last months, the memory usage in the dashboard has been increasing and is now showing 946.8 GB used of 1007.2 GB. What can be causing this? TIA, -- -- Tony Albers Systems Architect Systems Director, National Cultural Heritage Cluster Royal Danish Library, Victor Albecks Vej 1, 8000 Aarhus C, Denmark. Tel: +45 2566 2383 / +45 8946 2316

Ovirt Authentication extensions

13 Dec '18

I've seen the articles about hooking ovirt to AD and keycloak, but is there a way to hook it to something like ADFS? I'd like to have it require an MFA login and I know I can do it with ADFS.

Network Setup after ovirt node Install and before add node to cluster
by Stefan Wolf 12 Dec '18

12 Dec '18

Hello, I ve downloaded an installed OVIRT NODE 4.2.7.1. During the installation I ‘ve setup a static ip (I ‘ve also tried dhcp, both work) The installation passes and after the reboot ovirt node starts without any problems. BUT the network is not configured. I know https://www.ovirt.org/documentation/install-guide/chap-oVirt_Nodes/ and I know https://www.ovirt.org/documentation/admin-guide/chap-Hosts/ and now I am between these two documents oVirt is installed but network is not configured to add it to datacenter of course I know the scripts under /etc/sysconfig/network-scripts do I really have do edit it manuel? if I change ip in command line ip a add … dev.. and ip route add … it fails to add node to datacenter - with one of the last version I ‘ve added the IP address in bash - added the host to datacenter, - after reboot readd the ip address in bash after reboot - an then I could change network settings in oVirt Manger What is best practices for adding a node to datacenter when the ip address is not assigned after installation Thx shb

Ovirt Maximums
by Brian Wilson 12 Dec '18

12 Dec '18

Is there a resource available that would describe the configurable maximums for the Ovirt Engine and Ovirt Nodes. Things like: How many Logical Networks per host? If one does not exist does anyone have any experiences with reaching limits that caused issues specifically with regards to the number of networks on hosts.

Configuring Gluster Hyperconverged on Cloud
by pawan.ratwani＠tcs.com 11 Dec '18

11 Dec '18

Hi, I would like to do hands-on on Gluster Hyperconverged environment, and as per my understanding compute and storage has to be on the same hosts. Since I don't have physical infra to support such configuration, I would like to setup 3-node cluster on Cloud e.g. AWS, or Azure. I would like to know if I create an EC2 instance on AWS (or on Azure) with the desired Compute, Storage and Network capacity, is Gluster-hyperconverged cluster setup supported for such deployment ? I am referring https://www.ovirt.org/documentation/gluster-hyperconverged/ for this. Thanks.
