Hello:
Recently I downloaded the ovirt stable node image. According to
releases notes since 2.2.2 UEFI installation bug has been fixed,
but I still can't boot from my server with UEFI. Ovirt installs
without problem, but when the system reboots nothing happens,
the system don't boot. Then I try to boot with super grub disk 2
live cd, it detects ovirt installation and boots the system.
I think that still there is a problem with UEFI in certain hardware:
Mi system is a IBM blade center HS22 7870
Can anyone confirm problems with UEFI in 2.2.2 version?
Thanks
Federico

Can you boot the image like you did with the grub livecd and run
efibootmgr -v also mount /dev/disk/by-label/EFI and run find on
where you mounted it.
Ok,
efibootmgr -v
Fatal: Couldn't open either sysfs or procfs directories for
accessing EFI variables.
Try 'modprobe efivars' as root
I can't mount /dev/disk/by-label/EFI, when I create a directory and
try to mount the partition, mount says:
mount: /dev/sda1 already mounted or disco busy
however, mount output don't show that /dev/sda1 is mounted
Some directories are in read only mode and I could not create a
directory to mount the partition, I tried into /config and /live.
/dev/disk/by-label/EFI points to /dev/sda1 and "disco" is the
directory mount point.
Also, /proc/efi/vars/ and /sys/firmware/efi/vars/ are not present
Thanks

Ah.. was assuming the grub disc you booted from was EFI enabled. Try
booting the node iso in EFI mode and run through those steps again.
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
EFI boot process is done before the grub config comes into play, and
the grub config has a few extra lines in it. The machine I'm testing
on when you goto the boot menu will show UEFI: $CD_DEVICE_NAME or for
boot entries for ovirt it would show: oVirt Node Hypervisor If your
grub cd supports efi booting it will be noticeable in the boot menu.
In order to do an efi installation it has to be booted in efi mode for
it to properly setup the boot entries.
Before the Ovirt entry on Grub menu, Grub2 displays the config detected:
setparams '(hd0,gpt3)/grub2/grub.cfg' 'hd0,gpt3'
'(hd0,gpt3)/grub2/grub.cfg'
cfg_device="$2"
cfg="$3"
root="$cfg_device"
configfile "$cfg"
Is there where "UEFI:" parameter must be present?
Sorry, I am a newbie to UEFI and Grub2, meanwhile I am reading all I can
about Grub2 and UEFI
Thanks
Thanks
