[ovirt-users] VM => "No bootable device" on Centos 7 VDSM, 6.5 boots perfectly

Hi guys, I have installed a new host with Centos 7 on a 3.4.1 engine. I have attached the right networks for the VM and strorage is attached an mounted well. When I start the VM, connecting to the graphical console takes very long and when I finally get it my PXEboot is done and wants to boo local but it doesn't see any disk it seems. When I boot the same machine on an existing 6.5 host it boots with away. Any idea here? Thanks! Matt
