non-redhat version of ovirt-host-deploy
by ivan.kabaivanov＠gmail.com 28 Feb '19

28 Feb '19

Hi, I'm trying to get ovirt working on Linux From Scratch. So far so good, I can build and install it, and engine-setup also works fine. Now, I'm at the last stage, configuring it. And this is where I hit serious trouble: ovirt-host-deploy requires dnf/yum/rpm. But since I'm not running a redhat-based distro, I have none of those. Short of reading the source code, what are the steps I need to manually perform to get a working host? Thanks, IvanK.

Host ends up non-operational after trying to add it to cluster
by Kristian Petersen 26 Feb '19

26 Feb '19

Hello all, I am building a small two-host oVirt cluster and am experiencing problems adding in the second host. The engine log shows a message saying it is marking the host as non-operational due to it not meeting minimum CPU requirements. However, both hosts are the using the same i7-4770 model CPUs. For some reason, oVirt detects them as the same model but the "CPU Type" from ost1 is listed as "Intel Haswell-noTSX IBRS SSBD Family" while host2's CPU Type is listed as "Intel Haswell-noTSX Family". The two computers are supposedly the exact same model from Dell with the same hardware in them. Anyone have any insight into this issue? -- Kristian Petersen System Administrator BYU Dept. of Chemistry and Biochemistry
