I recently changed the kernel command line of one of my hosts using oVirt Manager (a custom kernel command line, not one obtained by choose a list of standard features). This did not work as expected. The kernel options I specify are added to the real kernel command line as an unique single-quoted string, therefore the kernel does not recognize them.
For example, this is the file /boot/loader/entries/ovirt-node-ng-4.5.3.2-0.20221028.0+1-4.18.0-408.el8.x86_64.conf which I get in one of my hosts:

You can see that the last part of the options is surrounded by quotes. I can later fix the problem by manually changing the files in /boot/loader/entries/, but this makes the GUI option useless.
