Bingo!

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
