[ovirt-users] hosted engine wrong bios

Hi, i run with ovirt node 4.4.2 in some old mistake. I changed cluster default to uefi weeks ago. now today node must be restarted, and now i cannot work. manager VM try to boot on uefi. and all other vm are down, because i cannot start anny with cli. how can i change (some config, file or something els) that setting in this vm to normal bios? Greetings Michael
