Sorry, I sent to the private. I resend to the list:

Super grub disk detects the grub.cfg from ovirt's installation and loads 
the system from this configuration. Therefore I assume that the kernel 
parameters from grub config loads the system with EFI enabled.

The grub config from grub's console is:

setparams 'oVirt Node Hypervisor 2.2.2-2.2.fc16'

set root=(hd0,3)
linux /vmlinuz0 root=live:LABEL=Root ro rootfstype=auto rootflags=ro 
crashkernel=512M-2G:64M,2G-:128M elevator=deadline quiet rd_NO_LVM rhgb 
rd.luks=0 rd.md=0 rd.dm=0
initrd /initrd0.img
