### 1.  PROBLEM: unable to clone the RHEL 9 VM or import VM from .ova file, with the new VM unable to boot
        SOLUTION: 2 parts to the solution, both to be done

               (1)  Make sure that in /etc/fstab, the /boot partition was not mounted using UUID,
        e.g. use partition for the device to mount to /boot

        BAD:
        UUID=d3f8b7ca-982e-401a-9d1f-f1185d2961bb /boot                   xfs     defaults        0 0

        GOOD:
        - find the partition for /boot

        [root@ansible9 etc]# lsblk
        NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
        sda             8:0    0  100G  0 disk
        ├─sda1          8:1    0    1G  0 part /boot
        └─sda2          8:2    0   99G  0 part
          ├─rhel-root 253:0    0 65.2G  0 lvm  /
          ├─rhel-swap 253:1    0    2G  0 lvm  [SWAP]
          └─rhel-home 253:2    0 31.8G  0 lvm  /home
        sr0            11:0    1   51M  0 rom  /run/media/abdulrahman/VBox_GAs_7.0.10

        - then use the following in /etc/fstab
        /dev/sda1               /boot                   xfs     defaults        0 0


       (2) Ensure LVM does not use devices file

       Edit /etc/lvm/lvm.conf and insert the following line

       use_devicesfile = 0

       Delete /etc/lvm/devices/system.devices
