Just for closing the discussion and updating anyone that could find
this thread while looking for infos about UEFI, oVirt-node and PXE:

I managed to complete a full pxe setup of several ovirt nodes with
release 4.1.6 without issues. Nodes wait some time in blank screen
with blinking, but then boot completes.

I confirm, if i boot via CD i see that value. So now i try to do the
same via PXE and run a setup using UEFI.

The only "issue" i've seen is that after bootloader menù, screen
remains on blinking cursor for several seconds. Seems it's on hang.
If you have enough patience to wait, boot continues.

I'll measure the timing and report, but is an issue that also other
people is experiencing?

Re: [ovirt-users] Failed to open grubx64.efi

[Yuval Turgeman]

Hi,

I checked a little more, anaconda uses blivet to detect if the machine is
EFI for its boot partition requirements, and blivet checks if
/sys/firmware/efi exists [1].
The kernel registers /sys/firmware/efi only if EFI_BOOT is enabled [2], and
this is set in on setup, when the kernel searches for an EFI loader
signature
in boot_params [3] (the signatures are defined as "EL32" and "EL64").

You can access boot_params under /sys/kernel/boot_params/data, so if you
want
to understand what's going on with your machine, you can try to use strings
to
see if it's enabled while running anaconda - on my test machine it looks
like this:


[anaconda root@localhost ~]# strings /sys/kernel/boot_params/data

EL64

fHdrS


Hope this helps :)
Yuval.

Re: [ovirt-users] Failed to open grubx64.efi

[Yuval Turgeman]

Boot partition reqs should be handled the same on both ovirt node and
centos (or rhel) and you having to add this manually on rhel can give us a
hint that this is a bug in anaconda (doesnt detect efi?).

In other words, if you need to add this to rhel you'd need to add it to
ovirt node and autopart shouldnt scare you off, just follow the
partitioning guidelines, add your changes and you are all set.  You can
grab some ks examples here:

git clone https://gerrit.ovirt.org/ovirt-node-ng

Hi,

on the same hardware i can install with success rhel 7.4 using UEFI.
This required to change my default partitioning to another one
containing
/boot/efi/ partition, adding this entry:

part /boot/efi --fstype=efi --size=200 --ondisk=sda

I suppose that autopart doesn't create this partition.

Hi,

I tried to recreate this without success, i'll try with different hw
tomorrow.
The thing is, autopart with thinp doesn't mean that everything is lvm-thin
- /boot should be a regular (primary) partition (for details you can check
anaconda's ovirt install class)
This could be a bug in anaconda or in the kickstart that deploys the node
(if not installing directly from the iso), can you install CentOS-7.4 with
UEFI enabled on this machine ?  If you have some installation logs, that
would help :)

Thanks,
Yuval.

Hi Luca.

But do you have installed Ovirt without UEFI in production environments?.

UEFI , is it necessary in production environments?.

Hi Luca and Magnus,

I downloaded and installed ovirt-node-ng-installer-ovirt-4.1-2017110820, in
blade HS 22, without set legacy mode and this installation was successed.

Thanks a lot for you help

Looking around i've seen that there is an Alt+B sequence for booting
in legacy mode. Maybe in the system setup there is an option to choose
this legacy mode by default.

I don't know how to do it on your hardware, sorry

Are you also booting in legacy mode?

I had the same problem with a newer Lenovo Blade (x240 M5, IIRC).
The problem is that ovirt-node-ng by default uses autopart with thin
provisioning and that partition scheme doesn't create /boot/efi drive.

Without that drive, grub-efi cannot be installed.

I switched my blades back to legacy only and everything worked as expected.

I'm planning to extend my tests with UEFI in future, but at the moment
i don't see the necessity switch from legacy mode.

Luca
