The VM booted fine after /etc/fstab update!
I did another test, which was also successful.
Below follows the output from the process (after booting in troubleshooting mode using the CentOS 7 media disk):
1) Continue
2) Read-only mount
3) Skip to shell
4) Quit (Reboot)
Please make a selection from the above: 1 ======================================================= ======================================================= Rescue Mount
Your system has been mounted under /mmt/sysimage.
If you would like to make your system the root environment, run the command:
chroot /mnt/sysimage Please press <return> to get a shell. When finished, please exit from the shell and your system will reboot. sh-4.2# umount /dev/vda1 sh-4.2# xfs_admin -U restore /dev/vda1 Clearing log and setting UUID writing all SBs new UUID = b05227b2-7c86-4ccf-81ff-204a9a80f789 sh-4.2# mount /dev/vda1 /mmt/sysimage/boot sh-4.2# chroot /mnt/sysimage bash-4.2# grub2-install /dev/vda Installing for i386-pc platform. Installation finished. No error reported. bash-4.2# nano /etc/fstab bash-4.2# exit sh-4.2#
Note also that after logging into the (finally bootable) OS, we should follow the directions: "Resetting and Reinstalling GRUB 2".
