Hi Benny, thanks for the response! I tried what you suggested, but the moment I draged ovirtmgmt to eth0 and click OK that I lose connectivity to the engine, both ports 8443 and 22. After reboot it was still not there. I rolled back the snapshots, did re-setup of network interfaces on both machines (nmcli connection mod) and executed host setup again and this time it worked :) Mysteries :) Thank you for your help, Fedor ----- Original Message ----- From: "Benny Zlotnik" <bzlotnik(a)redhat.com&gt; To: "Fedor Gavrilov" <fgavrilo(a)redhat.com&gt; Cc: "devel" <devel(a)ovirt.org&gt; Sent: Monday, August 12, 2019 6:32:16 PM Subject: Re: [ovirt-devel] Failed to add CentOS 7 host try going to the network interfaces tab of your host, then click "setup host networks" and make sure ovirtmgmt is connected to an interface, usually you can just drag it if it isn't connected On Mon, Aug 12, 2019 at 6:50 PM Fedor Gavrilov <fgavrilo(a)redhat.com&gt; wrote: > Hi, > > Couple of days ago I had to refresh my dev environment to validate the > issue and since support for Fedora 28 is no longer there I used CentOS 7 > for both engine and host. > Vdsm and cockpit socket on host is from the package, engine is compiled > from git master.
