Re: Help installing oVirt on single machine, without cockpit
I think this thread (even if the title is not so clear about the discussions born inside) could be a good read regarding single host
The reply button is making me write an email, so hopefully this reaches you all. limitations in terms of updating the environment, after the initial deployment Cool, thanks for the advice! Based on the link, it seems like the hosted engine can't update on a "single machine" install. But if you install the engine directly to the host, the VM doesn't need to be running, so it might be able to. Thankfully I wasn't too far down playing with the hosted engine, or container setup yet. So with installing an engine directly to the node, I got it to install ovirt-engine, by enabling the appstream, baseos, extras, and powertools repo. Then I commented out all "includepkgs = ..." in both `/etc/yum.repos.d/ovirt-*.repo` files. I can also get through all of the `engine-setup` questions, but then it fails with starting the `ovirt-imageio` service at the very end. The logs in `/var/log/ovirt-imageio/daemon.log`: ```txt File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/ssl.py", line 16, in server_context purpose=ssl.Purpose.CLIENT_AUTH, cafile=cafile) File "/usr/lib64/python3.6/ssl.py", line 468, in create_default_context context.load_verify_locations(cafile, capath, cadata) FileNotFoundError: [Errno 2] No such file or directory ``` Which is the same error as this forum here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/DNB73ZMUB5DIMV7... But all the info about solving it is " Found it; Default route was set to the NFS / SAN Network Gateway, not the Actual gateway.", and I'm not exactly sure what that means. I also tried the engine install/setup in a CentOS workstation VM, and it worked great, so I thought the node is missing a package? I installed `openssl-devel` without any luck. In both the VM and the node, I tried `route -n`, and both CentOS vm / node had similar/expected output. I tried to do as many default options as possible on both, so I'm surprised the gateway is different between them. Any idea how to get past this? I'm also open to switching to plain CentOS if that might be more stable, and installing to that. I just love how a lot of the node comes pre-packaged for you, and I'm not sure if you can install a "node hypervisor" straight to CentOS. That's also outside my comfort zone, so I'm open to advice either way. Thanks all for letting me get just this far!
Have you thought about deploying HostedEngine and when you need to update the engine -> put the host in maintenance -> backup & restore .This way you both test the backup and upgrade your versions.
