changed hosted-engine hostname but websocket proxy has old hostname
by Douglas Duckworth 15 Dec '18

15 Dec '18

Hi I change the hostname of my hosted engine using script below: https://www.ovirt.org/documentation/how-to/networking/changing-engine-hostn… However, as shown attached, the old hostname of "ovirt-engine.pbtech" seems to still be expected for some reason. As a result I cannot connect to VMs via console. Any idea on how to make WSS to use the proper hostname? In file "https://www.ovirt.org/documentation/how-to/networking/changing-engine-hostn…" I defined "PROXY_HOST=FQDN" then restarted ovirt-websocket-proxy.service but no change. Thanks very much!

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.

Correct email for this would be users(a)ovirt.org (added) I also suggest that you attach the logs from the engine and the host machines On Thu, Dec 13, 2018 at 9:30 PM Shoeb Chowdhury <shoeb.ch(a)gmail.com> wrote: > I've installed oVirt Node 4.2.0 in one physical server and oVirt Engine > 4.2.7.5-1.el7 in another physical server.

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?

Ovirt Authentication extensions
by darkytoo＠gmail.com 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.
