Aha!!

image, to get the grub set up, is to delete the kernel from the guest
domain and do a virt-install "upgrade" on top of it.

I did a virt-install that was really an upgrade, and paravirtualized
"mode" works now! Now I'll just try to coax the VM to run in fully
virtualized mode again - it didn't like my new kernel.. Thanks you very
much for your help!
