Great work!
It would be nice if you had the time to update this guide to the new oVirt 4.2.1 version! There are some new things in the new versions installation I believe.

Hello.
I use two laptops to try out oVirt and both use WLAN as internet access. The isntallation of oVirt – Engine was successful and I wanted to add the second laptop as a host. On both I installed CentOS 7 which is valid for using oVirt. When I want to add the host in the webportal it fails with the message: failed to configure management network on the host ovirt.
What is the problem on the host? Is it a DNS problem? I really need help. Thanks

Hi,

Good Documentation. I have a Centos 7.4 installation with “Virtual host” option alone. Does that mean now i can consider this as a ovirt node and skip most of the installation steps under “Installation Steps of oVirt Node”.

In reply to Stefano Stagnaro.

You can specify an alternative FQDN simply by editing the SSO_ALTERNATE_ENGINE_FQDNS variable in /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf on the oVirt Engine.

ENGINE_SSO_CLIENT_ID=”ovirt-engine-core”
ENGINE_SSO_CLIENT_SECRET=”FWkrOehmAMofkF9ZPlnxUKl3Epr4BOJf”
ENGINE_SSO_AUTH_URL=”https://${ENGINE_FQDN}:443/ovirt-engine/sso”
ENGINE_SSO_SERVICE_URL=”https://localhost:443/ovirt-engine/sso”
ENGINE_SSO_SERVICE_SSL_VERIFY_HOST=false
ENGINE_SSO_SERVICE_SSL_VERIFY_CHAIN=true
SSO_ALTERNATE_ENGINE_FQDNS=” here need to specify FQDN”
SSO_ENGINE_URL=”https://${ENGINE_FQDN}:443/ovirt-engine/”

eescape :wq

then restat the engine-
## systemctl restart ovirt-engine.service

thank you.
I’ve search more about it, and also I found that once installed you can migrate the ovirt-engine into a new machine inside the hosts.

In reply to txsastre. Hi, oVirt engine can be installed in a CentOS 7 VM outside of oVirt Nodes, whereas oVirt Node will be installed on Physical machine or in Lab it can be installed on Virtual Machines.

hi ! thanks for the tutorial.

question: now I have 3 servers with xenserver, how could I do the same installation with oVirt ?
I assume that ovirtnode is for each hardware machine, but where do I have to install the ovirt engine ? Can it be hosted inside a host ? or do I have to need an extra machine to have ovirt engine

thanks !!

Also if you want the gpg key, I used `wget -O /etc/pki/rpm-gpg/RPM-GPG-ovirt-4.0 http://resources.ovirt.org/pub/keys/RPM-GPG-ovirt-v2`
