[ovirt-users] Re: Newer kernel for oVirt Node NG
Tried it again, it just breaks the boot.
After a lot of firefighting found that elrepo kernel-lt doesn't have `xfs`
in initramfs image and it fails mounting the lvm which uses xfs
# lsinitrd /boot/initramfs-4.18.0-240.1.1.el8_3.x86_64.img | grep xfs.ko
-rw-r--r-- 1 root root 442760 Aug 11 2020
usr/lib/modules/4.18.0-240.1.1.el8_3.x86_64/kernel/fs/xfs/xfs.ko.xz
Tested kernel-ml and it has the needed xfs module
After installing the new kernel, I needed to copy over the "options" line
from /boot/loader/entries/ovirt*.conf to the new one.
Hope this saves a lot of hair pulling for someone.

‘Node’ images are just minimal CentOS plus all the packages for this

system is still CentOS, and can be patched/modified, including installing
alternative kernels.
If it fails, boot back to the original kernel, and remove the package from
Elrepo, or at worse, re-install.

Thanks Matthew,
Are you sure about this?
I thought oVirt Node NG images are immutable

Hi oVirt Users,
I am trying to test some vfio related stuff on oVirt Node NG 4.4.4 based
host.
What would be the easiest way to have a 5.x kernel on this node?
I don't mind compiling if it needs to.
Cheers,
Shantur
