That's weird. Can you check in yum.log (or yum history) if you ever had it, and when/why it was removed?

[root@ov200 ~]#

yum search ovirt-host:

===================================== N/S matched: ovirt-host ====================================== ovirt-host-deploy-common.noarch : Commong files for ovirt-host-deploy ovirt-host-deploy-java.noarch : ovirt-host-deploy java support ovirt-host-deploy-javadoc.noarch : Javadocs for ovirt-host-deploy ovirt-host.x86_64 : Track required packages for oVirt hosts ovirt-host-dependencies.x86_64 : This meta package pulls in all the dependencies needed for minimal : oVirt hosts. ovirt-hosted-engine-ha.noarch : oVirt Hosted Engine High Availability Manager ovirt-hosted-engine-setup.noarch : oVirt Hosted Engine setup tool python2-ovirt-host-deploy.noarch : oVirt host deploy tool

This is not an oVirt-NG host, but plain CentOS....

What to do? Do I have to install the ovirt-host package anyway?

If you try to, does it bring with it any dependencies? Generally speaking: ovirt-host is a meta-package, not providing any content by itself, that depends on all the packages that we need on oVirt hosts. It's installed by default in node (it's actually the main means used to decide what to put there, other than base OS), installed/updated by ovirt-host-deploy, etc. So, yes, you should install it. If, when you try to install it, it does not add any dependencies with it, then strictly speaking, you do not have to, because it will do nothing (other than get rid of the icon in the ui).

yes, 148 dependent packages.... See full output here, I didn't apply at the moment https://drive.google.com/file/d/1hpkREaUFTVYTagLLIvCIF0xDR4zRVC96/view?usp=s...

Please note that this environment, external engine and CentOS hosts, was initially installed in 4.0.6 at beginning of 2017. Donna if this can be of impact.

ovirt-host was introduced in 4.2 [1] and back-ported to 4.1 at 4.1.7 [2], to allow adding 4.1 hosts to 4.2 engines [3]. In principle, it might have been possible to do something like: 1. Install 4.0 host and add it to 4.0 engine 2. Update to 4.1 using 'yum update' 3. Same, to 4.2 4. Same, to 4.3 Then, you'll get correct vdsm, which should be enough for the engine to be able to talk to it and behave as if all is ok.

Up to 4.3.2 and initial 4.3.3 the hosts didn't get this kind of requirement. It was a bug before or perhaps a problem introduced by the 4.3.3 async updates

Weird. How do you update your hosts? Only via 'yum update'? The engine admin ui? Something else? And you never saw "updates available" icon in the ui? Adding Martin. Best regards, -- Didi
