According to: https://bugzilla.redhat.com/show_bug.cgi?id=1029507 and https://rhn.redhat.com/errata/RHEA-2015-0213.html RHEV-M appliance should be available to customers for downloading. However, it is not. From this page: https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=24821 trying to click the link and it says - download not found: "Download object : /rhn/isos/rhevm-appliance-3.5/rhel-x86_64-server-6-rhevm-3.5/rhevm-appliance-20150129.0-1.x86_64.rhevm.ova"
I can verify that link "RHEV-M Appliance (for RHEV-M 3.5)" on site https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=24821 points to valid OVA file at /rhn/isos/rhevm-appliance-3.5/rhel-x86_64-server-6-rhevm-3.5/rhevm-appliance-20150129.0-1.x86_64.rhevm.ova Before moving to verified I am waiting for Fabian's needinfo to confirm what image formats we should provide.
I can confirm that the OVA is for download now on the page given in comment 6.
Verified, see comment 6 and comment 7.
