follow the following instructions on each node of the Ovirt Engine Cluster servers:
Install CentOS 7.2
The disk named virt is going to host the VM image of the VM that contains the OVirt Engine. This device is passed directly to the ovirt-engine KVM.
The sync disk is used for different configuration files that are shared between the cluster nodes. Examples are the configuration of the openVPN cluster resource.
Download and execute script that installs required packages
wget -O - https://github.com/linuskohl/DHVLab/raw/master/scripts/ovirt-engine-cluster/install_packages.sh | bash
Create the following setup using the network configuration files.
#disable the NetworkManager and switch to manual configuration systemctl stop Networkmanager systemctl disable NetworkManager systemctl mask NetworkManager chkconfig network on #disable firewalld for switching to iptables systemctl stop firewalld systemctl disable firewalld systemctl mask firewalld #disable SELinux nano -w /etc/selinux/config #change line SELINUX=enabled to disabled #write with ctrl+o and ctrl+x #configure NTP client cat << EOT >> /etc/ntp.conf server your.ntp.server1 server your.ntp.server2 interface ignore wildcard interface listen 127.0.0.1 interface listen ::1 EOT #add cron job echo "30 * * * * root /usr/sbin/ntpd -q -u ntp:ntp" >> /etc/cron.d/ntpd systemctl start ntpd systemctl enable ntpd #setup resolve.conf cat << EOT > /etc/resolv.conf search YOUR_DOMAIN nameserver YOUR_PRIMARY_NS nameserver YOUR_SECONDARY_NS nameserver 18.104.22.168 EOT #setup hosts configuration file wget -O ./hosts_file https://raw.githubusercontent.com/linuskohl/DHVLab/master/configfiles/ovirt-engine-cluster/etc/hosts #adapt using nano nano -w ./hosts_file #overwrite hosts file sudo mv ./hosts_file /etc/hosts
