Hi,all
        I want to install redhat5.8 in graphical mode. I can install it in ovirt3.5(picture1), but I cann't install it in ovirt4.0(picture2). I cann't see the three selections in ovirt4.0. I use rhel-server-5.8-x86_64-dvd.iso.



I don't have at hand a rhel 5.8 iso but I reproduced the same problem with rhel 5.11 iso too (and oVirt 4.0.5 with CentOS 7.2 at hypervisor side)
I verified that in edit VM, console, the only "Video Type" option that works is "Cirrus", while with QXL and VGA I get the same problem described by you.
I think you can install in graphic mode with Cirrus video type and then setup the operating system for QXL in a second time, also taking in account what detailed in this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=890230
(or keep Cirrus+VNC graphical access also after install)

HIH,
