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.

Ovirt 4.3 Alpha AMD 2970WX Windows VM creation and NUMA
by Darin Schmidt 13 Dec '18

13 Dec '18

Not sure if Users is the best place for this as Im using 4.3 to test support for my AMD 2970WX Threadripper but While trying to setup a Windows VM, it fails. I have a working CentOS 7 running. Heres what I get when I try to startup the VM. VM Windows-Darin is down with error. Exit message: internal error: process exited while connecting to monitor: WARNING: Image format was not specified for '/dev/sg0' and probing guessed raw. Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.

I also dont fully understand NUMA because it creates 4 NUMA sockets even though technically there should be 2 correct? I dont get how NUMA is setup, but either way it doesnt help resolve any issues.

removal of 3 vdsm hooks
by Dan Kenigsberg 13 Dec '18

13 Dec '18

I've identified 3 ancient vdsm-hooks that have been obsoleted by proper oVirt features. vdsm-hook-isolatedvlan: obsoleted in ovirt-4.2.6 by clean-traffic-gateway filter https://gerrit.ovirt.org/#/q/I396243e1943eca245ab4da64bb286da19f9b47ec vdsm-hook-qos: obsoleted in ovirt-3.3 by https://www.ovirt.org/documentation/sla/network-qos/ vdsm-hook-noipspoof: obsoleted in ovirt-4.0 by choosing the "clean-traffic" filter https://ovirt.org/feature/networkfilter I would like to remove this code from vdsm-4.30, destined for ovirt-4.3. Is there any objection for that? Is anybody still using them? Regards, Dan.

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.
