Hi, i just want to add some additional info which I didn't saw mentioned anywhere. When you install from the ovirt.org repo you need some additional packages from EPEL. So, after installing EPEL, use this ovirt.org repo: yum install http://resources.ovirt.org/releases/3.3/rpm/EL/6/noarch/ovirt-release-el6-8-... (if you want 3.3) now, install the following EPEL packages: yum install novnc python-ply python-kitchen python-daemon now _deactivate_ epel! Why? Well EPEL holds also ovirt-packages, which have different versions then the ones provided via ovirt.org repo, you don't want to mix them: sed -i 's/enabled=1/enabled=0/' /etc/yum.repos.d/epel.repo now, install ovirt-engine: yum install ovirt-engine tested and works with CentOS 6.4 x64 and oVirt 3.3 HTH Sven PS: On a personal note: 3.2 is still more stable than 3.3, but ymmv for nodes I would stick with CentOS minimal + VDSM from ovirt.org repo
