1)清理ovirt相关服务(包括HA,engine):
停用并卸载ovirt,vdsm,libvirt相关的服务。
yum remove ovirt vdsm libvirt rhev glusterfs postgresql
rm -rf /etc/ovirt /etc/vdsm /etc/libvirt /etc/pki/vdsm /etc/pki/libvirt /etc/pki/CA/cacert.pem /var/run/vdsm /var/run/libvirt /var/lib/vdsm /var/lib/libvirt /var/lib/ovirt /var/lib/pgsql /var/log/ovirt /var/log/vdsm /var/log/libvirt

如果需要清理vdsm管理的multipath:
首先,查看列表:
multipath -l
清空:
multipath -F
移除包:
yum remove multipath
2)
安装:yum install ovirt-engine ovirt-engine-dwh
恢复数据库:engine-backup --mode=restore --log=restore1.log --file=备份数据路径 --provision-db --provision-dwh-db --no-restore-permissions
配置:engine-setup
