For the Install section of the docs, we specify: "The Red Hat Enterprise Virtualization Manager must be installed on a base installation of Red Hat Enterprise Linux 6.6 or 6.7" This may have been the release version at the time, but I'm not aware that this is an actual restriction. One of the installation steps is to run 'yum -y update' anyway, which takes RHEL up to the later version. Less confusing wording might be something like. "The Red Hat Enterprise Virtualization Manager must be installed on a base installation of Red Hat Enterprise Linux 6.6 or later." FYI, the wording in the RHEV 4.0 Beta docs: "The Red Hat Virtualization Manager must be installed on a base installation of Red Hat Enterprise Linux 7" [1] https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Installation_Guide/chap-System_Requirements.html [2] https://access.redhat.com/documentation/en/red-hat-virtualization/4.0-beta/installation-guide/#chap-System_Requirements
