If so, may it be that this fix has not been rolled out to CentOS repos yet? What is your opinion and your advice/suggestion(s)? Thanks, Nick

I never used xfs for /boot. Also on CentOS 7 I tipically format it with ext4.

I had to unmount the boot partition (being in Troubleshooting mode), run the above command, which provided a new UUID and at last the partition was recognized as xfs. (I forgot to copy the output to paste here.) I then mounted the boot partition again, chrooted, grub2-install'ed successfully, exited and rebooted. The VM started booting, seemingly well, but after some time it took me to emergency mode. ("Give root password for maintenance or type Ctrl-D to continue.") I'll have to check that tomorrow... I need some sleep now (it's after midnight over here - in Athens, Greece). [Perhaps I should have manually edited /etc/fstab as well to enter the new UUID?] Anyway, that was a good progress! Thanks for your great cooperation. I'll keep you updated. Cheers, Nick
